需求：开发个LEDC的驱动，netlink方式传输数据，控制至少80个灯，要能过72小时压力测试

可以用全志的ledc驱动重新开发

或者是把我写好的拿去DEBUG

出现的问题就是ledc驱动会崩溃，超过6小时DMA也奔溃了
有兴趣的大佬联系我呀 flyingbearno1

make -j
以后
pack指令这个之前如何把自己的应用app编译好的可执行文件塞到img的镜像里面去啊
我之前尝试过往下面这个文件夹里面塞，但是直接在编译的时候就报错啦

/home/tina_whycanpii/tina_d1_open_v2_for_whycanpi/target/allwinner/t113-whycanpii/busybox-init-base-files/etc/init.d

那么各位大佬如何把自己的app塞到镜像里面去呢？

反正前6个小时能稳定运行，但是6小时以后就不行了

那个驱动程序我改了个数据传输的部分，用了netlink
之前也有个bug能带崩溃整个系统，但是我后来修复了那个问题
现在这个报错会是什么问题呢，看起来像是DMA挂了

这个只有长时间运行才发生
那么有木有办法给这个DMA重置一下啊，就像内存整理那样，我每6小时给它整理一下应该也能用

这个错误一旦发生了，这个ledc驱动基本上就彻底罢工了，停止程序重新发包也木有用，只能重启系统

我那个程序操作ledc 驱动会一直不停发数据，一直用，就是RGB背光那种幻彩运动的效果

@leomini5 这个我自己解决了……不是驱动的锅

@leomini5 这个问题我解决了，不是驱动的锅，是内核其他驱动的锅

运行3小时，网卡就蹦了
还带着系统一起蹦了，这怎么玩啊

哈哈哈，我自己搞定了，嘿嘿嘿

我按照usb开发手册倒腾了一圈，那个ttyGS0 也出了，但是连上pc，没有任何反应
确认线是好的，setusbconfig adb，adb有效
修改成 rndis，win10系统无法使用，驱动都是感叹号，貌似是win10就不爱支持这个，要么就是驱动太老啦？反正死活没法联通
现在寄希望于acm cdc ，但是貌似也没用。。。

而且我发现这东西编译进内核以后连那个 soc/usb0
去找usb的role都没有显示的。。。

下面这个是完整的log，我是在系统加载好以后去用那个acm.sh加载usb0 的 acm cdc，但是不成功

哪位大佬能够提供一份完整的usb acm cdc，这个功能的教程啊，谢谢啦

我之前玩那个ledc驱动器嘛，tina系统里面的那个其实不太好用，每次要echo 数据去那个device是不行的，一个指令只能设置一个灯的1/3，那么100fps 设置80个灯就要炸啦，系统直接宕机

后来我找啦个办法直接往内核发数据，爽歪歪啦

操作那个灯的方法现在变成了

1 准备好80个灯的数据
2 发送给内核驱动
3 驱动读取数据 交给DMA 一次写80个灯的数据

那么800k的 ws2812的数据波，算下来80个灯一次传送数据大概在 2ms，抛开数据准备的时间也就3ms 80个灯的数据，加个sleep，一帧10ms都是绰绰有余的，那么100fps，完全没问题，使用方法也很简单，啥额外的驱动读取都不需要，直接往内核发数据包，内核驱动接就好啦

亲测效果很好

【RGB只要开始玩就停不下来，这个全志的ledc用起来终于顺心了，DMA传输数据，反正跑个100fps没有一点压力哪位大佬有玩过lua代码在线编译执行的呀我…】 https://www.bilibili.com/video/BV1TJ4m1h7Gk/?share_source=copy_web

我是直接通过netlink去实现往内核驱动写数据的

所以得先打开 tina linux里面 lib中相关的库

make menuconfig

Libraries 里面涉及到netlink的库给它打开以后就可以用啦

上面那个相当于内核里面的服务端，功能也很简单，就是接收数据，收到后直接丢给dma，发送出去

下面这个是客户端，也就是你的app
大概写个发送数据的代码就行啦，超级简单，哈哈哈

大概的代码如下
大家可以参考下

#include <string.h>
#include <sys/socket.h>
#include <linux/netlink.h>


// net 方式往内核发送信息

    int sock_fd, len;
    struct sockaddr_nl src_addr, dst_addr;
    struct nlmsghdr * nlh;
    char msg[MSG_SIZE] = {0};

    sock_fd = socket(AF_NETLINK, SOCK_RAW, NETLINK_TEST);
    if(sock_fd < 0) {
        perror("socket");
        exit(EXIT_FAILURE);
    }
    /**/
    memset(&src_addr, 0, sizeof(struct sockaddr_nl));
    src_addr.nl_family = AF_NETLINK;
    src_addr.nl_pid    = getpid();

    bind(sock_fd, (struct sockaddr *)&src_addr, sizeof(struct sockaddr_nl));

    memset(&dst_addr, 0, sizeof(struct sockaddr_nl));
    dst_addr.nl_family = AF_NETLINK;
    dst_addr.nl_pid    = 0; // send to kernel
    dst_addr.nl_groups = 0; // unicast

    nlh = (struct nlmsghdr *)malloc(NLMSG_SPACE(MSG_SIZE));
    memset(nlh, 0, NLMSG_SPACE(MSG_SIZE));
    nlh->nlmsg_len   = NLMSG_SPACE(MSG_SIZE);
    nlh->nlmsg_pid   = getpid();
    nlh->nlmsg_flags = 0;

    char buf[MAX_PAYLOAD] = {0};
    // sprintf(cmd, "echo 10 > /sys/class/leds/sunxi_led79r/brightness");

    struct color_hsv color_hsv_test;
    u_int16_t test_h = 0;
    color_hsv_test   = color_hsv(100, 250, 0);

    int len = sizeof(led_data);

    int    bright2=0;
    u_int16_t t_flag=   0;
    printf("start check led!\n");
    while(!is_stop){

        if(t_flag == 0) {
            bright2 = bright2 + 4;
        } else {
            bright2 = bright2 - 4;

            is_stop=1;//放完停掉
            //usleep(50000);
            printf("stop led\n");
        }
        color_hsv_test.v    =   bright2;
        for(int i = 0; i < 80; i++) {

            led_data[i] = trans_hsv_u32(color_hsv_test);
        }


        memcpy(NLMSG_DATA(nlh), (const uint8_t *)led_data, len);
        if(sendto(sock_fd, nlh, nlh->nlmsg_len, 0, (struct sockaddr *)&dst_addr, sizeof(struct sockaddr_nl)) < 0) {
            perror("sendto");
            exit(EXIT_FAILURE);
        } else {

            break;
            return;
        }
    }

}

这里面有用的就是个 sendto函数

其他都是用来准备好数据包的，我这直接把数据整个发过去了
其实这么整效率不够高，最好是就发个数据包的地址过去
然后接收的位置，直接读那个地址里面的数据就行了

反正即便是这么写，跑起来也很快，基本不耗什么cpu

主要是简单啊，不用去理解linux底层驱动了，反正我也没搞明白怎么驱动的
反正就是用了netlink直接往内核驱动发包，内核驱动收到包以后直接执行。。。
直接执行，达到结果也是一样快。

@damiaa dts里面设置一下打开相应的uart，没有就加上就行啦，那个pin不能被其他的占用了，编译好后启动tina

系统里面就会有/dev/ttyS4 /dev/ttyS5
如果没有就dmesg看看启动的时候pin有没有报错

@awwwwa. 这个又随机出现了一次，这次好了，刚启动就卡了

@awwwwa log 被我关掉啦，啥也没
我那个报错是出现错误了以后通过dmesg看到的
这个故障等我回去有机会再长时间测试的时候接上个串口debug弄出来再看吧

暂时只有那一段出错的输出

之前也停过
但是那会能确定是ssh的锅
这个程序如果是后台运行的就没问题
然后这个之前开了输出的情况下，ssh时间久了以后也会爆掉，然后网络服务就全部都停掉了
只要是后台运行，或者是换到开机自动运行就没啥问题，干个几个小时也没事

@awwwwa 这个中断的优先级可以调高嘛？调高了以后会有影响吗？如何查看系统中的中断情况啊，也就是看看这个中断被谁给抢了

@leomini5 而且再补充一点是，我在这个驱动器上挂了80个灯
然后一直不停的往里面写数据，大概60fps的速度往里面写数据控制灯的颜色才出现上面这个错误的

而且我把驱动里面那个fifo深度改成0了，也就是默认DMA方式发送数据，一次发送80个

数据的来源是直接往led->data 里面写了80个灯的数据

而且这个情况很诡异，超时以后只能重启才能正常

所以想请教下各位大佬那个ledc的驱动为啥会超时呢？
写那段超时处理的代码的意义是什么啊？

那个ledc驱动在长时间跑大量数据之后出错啦

报错是这个超时的故障

sunxi_ledc_irq_handler()1313 - wait time is more than 600000 ns,going to reset ledc and drop this operation!

为啥会超时呢，一开始运行的都好好的
但是时间一长比如说，让这个ledc驱动器工作个1-2小时以后
这玩意就概率性的挂掉
报错看上去是超时
现象是有一半左右的灯组就不亮了，而且重启程序那部分不亮的灯也再也不会亮了

会不会是芯片过热或者被其他什么东西干扰了，我开机几个小时后那个芯片还是有点点热的

而且这个出错是概率性的，关机一段时间再启动又不会出错啦

下面是那个驱动报错那部分的代码

static irqreturn_t sunxi_ledc_irq_handler(int irq, void *dev_id)
{
	unsigned long flags;
	long delta_time_ns;
	u32 irq_status, max_ns;
	struct sunxi_led *led = sunxi_led_global;
	struct timespec64 current_time;

	spin_lock_irqsave(&led->lock, flags);

	irq_status = sunxi_get_reg(LEDC_INT_STS_REG_OFFSET);

	sunxi_ledc_clear_all_irq();

	if (irq_status & LEDC_TRANS_FINISH_INT) {
		sunxi_ledc_reset(led);
		led->length = 0;
		led->result = RESULT_COMPLETE;
		wake_up(&led->wait);
		goto out;
	}

	if (irq_status & LEDC_WAITDATA_TIMEOUT_INT) {
		ktime_get_coarse_real_ts64(&current_time);
		delta_time_ns = current_time.tv_sec - led->start_time.tv_sec;
		delta_time_ns *= 1000 * 1000 * 1000;
		delta_time_ns += current_time.tv_nsec - led->start_time.tv_nsec;

		max_ns = led->wait_data_time_ns;

		if (delta_time_ns <= max_ns) {
			spin_unlock_irqrestore(&led->lock, flags);
			return IRQ_HANDLED;
		}

		sunxi_ledc_reset(led);

		if (delta_time_ns <= max_ns * 2) {
			sunxi_ledc_dma_terminate(led);
			sunxi_ledc_trans_data(led);
		} else {
			LED_ERR("wait time is more than %d ns,"
				"going to reset ledc and drop this operation!\n",
				max_ns);
			led->result = RESULT_ERR;
			wake_up(&led->wait);
			led->length = 0;
		}

		goto out;
	}

	if (irq_status & LEDC_FIFO_OVERFLOW_INT) {
		LED_ERR("there exists fifo overflow issue, irq_status=0x%x!\n",
				irq_status);
		sunxi_ledc_reset(led);
		led->result = RESULT_ERR;
		wake_up(&led->wait);
		led->length = 0;
		goto out;
	}

out:
	spin_unlock_irqrestore(&led->lock, flags);
	return IRQ_HANDLED;
}

这个驱动里面带了个貌似用来测试led灯的代码

这个怎么在tina里面调用呀

static ssize_t led_show(struct class *class,
			struct class_attribute *attr,
			char *buf)
{
	struct sunxi_led *led = sunxi_led_global;

	sunxi_led_set_all(led, 0, 0);
	sunxi_led_set_all(led, 1, 0);
	sunxi_led_set_all(led, 2, 0);

	sunxi_led_set_all(led, 0, 20);
	msleep(500);
	sunxi_led_set_all(led, 1, 20);
	msleep(500);
	sunxi_led_set_all(led, 2, 20);
	msleep(500);

	sunxi_led_set_all(led, 0, 0);
	sunxi_led_set_all(led, 1, 0);
	sunxi_led_set_all(led, 2, 0);

	return 0;
}

static struct class_attribute led_class_attrs[] = {
	__ATTR(light, 0644, led_show, NULL),
	//__ATTR_NULL,
};

我在改那个tina的ledc驱动的时候想换中方式去发送数据

现在这个系统里面的ledc是一个个单独的brightness设置
就是用那个echo 去写单独的一个灯的 r g b ,这么搞一个灯就要写3次，每次写完以后都要单独发送，那么一个灯要发三次，80个灯要发240次，这么玩肯定不行

所以我是想改成先把数据准备好，然后再发送，那么80个灯只需要发送一次就行了

我测试了往最后那个灯发送数据去激活发送所有的灯，fps跑个100贞都是没什么问题的，那么现在就一个问题，如何把全部数据一次性高效的传输给驱动程序呢？

我想用那个linux的内存共享，用户端很简单啊，直接写内存里面
驱动去读也很快

但是这个tina里面的驱动程序貌似不能直接用

ftok（）
shmget（）

包括那个头文件也不太对

#include <linux/mman.h>
#include <linux/ipc.h>
#include <linux/shm.h>

这些文件都有，但是吧看起来内容不太对

drivers/leds/leds-sunxi.c: In function 'sunxi_set_led_brightness':

反正一编译就出错啦

各位大佬还，这tina的驱动程序里面怎么去使用共享内存呀

如果没法用的话，有木有其他什么高效简单的方式，让用户app给驱动倒腾数据呀，谢谢啦

@fanhuacloud 这么复杂啊。。。

@lyg116 全志自己的Xr829很快就能加载好，没啥问题

@awwwwa 终于破案了，那个dts里面ledc的配置有个数据被我改过 wait_data_time_ns 这玩意被我改得很小，我那会测试melis的时候32个灯数据，需要刷很快，所以这个数值就不能大，一旦了，数据就错，灯乱闪，我本以为这个数值不影响DMA，但是有影响

我改回到原来那个600000 就一切正常了，DMA能用了，如果这个数值设置太小就完蛋了，只要开启了DMA，系统就直接卡死！那个ledc的手册里面肯定没写全功能！

手册里面写了这么句
wait_data_time_ns：通过该节点可设置和读取 LEDC 内部 FIFO 等待数据的时间容忍度，
范围为 80ns-655us。

我改坏掉的

&ledc {
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&ledc_pins_a>;
	pinctrl-1 = <&ledc_pins_b>;
	led_count = <58>;
	output_mode = "GRB";
	//trans_mode  = "DMA";

	dmas = <&dma 42>, <&dma 42>;
	dma-names = "tx", "rx";
	
	reset_ns = <84>;
	t1h_ns = <800>;

	wait_time0_ns = <84>;
	wait_time1_ns = <84>;
	wait_data_time_ns = <3000>;
	status	= "okay";
};

就是那个 wait_data_time_ns 这个数值在我测试melis的时候被我改过，我以为仅仅是fifo会影响到，但是DMA模式下应该这个参数也有影响

改回来

&ledc {
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&ledc_pins_a>;
	pinctrl-1 = <&ledc_pins_b>;
	led_count = <58>;
	output_mode = "GRB";
	//trans_mode  = "DMA";

	dmas = <&dma 42>, <&dma 42>;
	dma-names = "tx", "rx";
	
	reset_ns = <84>;
	t1h_ns = <800>;
	t1l_ns = <320>;
	t0h_ns = <300>;
	t0l_ns = <800>;
	
	wait_time0_ns = <84>;
	wait_time1_ns = <84>;
	wait_data_time_ns = <600000>;
	status	= "okay";
};

大佬还有个问题想请教下
就是在tina里面能不能一口气把所有的灯的数据都设置好
然后再发送啊？
如果是
echo 1 > /sys/class/leds/sunxi_led0b/brightness

这样每改一次就要发送一次，效率太低

要同时驱动很多灯的时候 FPS就上不去啦

这要怎么处理呀

@fanhuacloud 我这里rtl8821cs也是这样
那个wl_reg_on 强制给他上个高电平貌似会快一些，我这加载模块要10s，连网要20s。。。
问了别人也是这个样子，全志的d1s，t113加载rtl的模块都很慢

@awwwwa

弄不好真是RV的bug我这是D1s上出现这种情况，我翻了一圈论坛里面貌似都是d1s 会出现这种情况，超过32个灯就出错了，那么这会是芯片的问题，还是代码的问题呢，如果是代码的问题还能搞搞好，如果是芯片的问题我就直接贴一片t113起来得了……

@awwwwa

大佬我这三份文件都和你发的是一样的

我测试了半天那个echo只要改变超过32个灯就直接挂掉了

如果把判断条件直接改成DMA模式，一个灯都亮不了呀

之前在melis里面测试的时候DMA模式就一直没能成功运行
现在换tina了问题依旧
只有cpu模式下能跑不超过32个灯

在leds-sunxi.c里面这块是选择发射方式的
如果小于32个灯那么就用fifo
超过32个的就用DMA
但是我在控制超过58个灯的过程中发现，这个驱动超过32个，系统就死机了
我一开始认为是我代码的问题
后来我改了这个驱动的条件直接全部用DMA模式发送
发现直接就死机了
如果修改了那个条件，把SUNXI_LEDC_FIFO_DEPTH加大到64也是不行的

if (led->length <= SUNXI_LEDC_FIFO_DEPTH) {

在超过32个灯的时候会报错
sunxi_ledc_irq_handler()1279 - there exists fifo overflow issue, irq_status=0x818010!

现在看来问题应该还是出在了这段DMA模式下控制ledc驱动器发送数据的代码上了，为啥会死机呢？

if (0) {

		dprintk(DEBUG_INFO, "cpu xfer\n");
		ktime_get_coarse_real_ts64(&(led->start_time));

		sunxi_ledc_enable(led);

		for (i = 0; i < led->length; i++)
			sunxi_set_reg(LEDC_DATA_REG_OFFSET, led->data[i]);

	} else {

	}

哈咯各位大佬
那个ledc的驱动我换了之前论坛里面提供的更新了，刷上去了以后那个调试节点 没有trans_mode 选项

root@TinaLinux:/sys/kernel/debug# cd sunxi_leds/
root@TinaLinux:/sys/kernel/debug/sunxi_leds# ls
data               output_mode        t0h_ns             t1h_ns             wait_data_time_ns  wait_time1_ns
hwversion          reset_ns           t0l_ns             t1l_ns             wait_time0_ns
root@TinaLinux:/sys/kernel/debug/sunxi_leds# cat wait_time
wait_time0_ns  wait_time1_ns
root@TinaLinux:/sys/kernel/debug/sunxi_leds# cat wait_time0_ns 
84

然后嘛我一共58个灯，这段程序只能点亮32个灯

void ledc_test(int brt)
{
	char cmd[64] = {0};
    int brit = 1;
	brit	=	brt;
    for(int i = 0; i < 58; i++) {
        ledcolor_r[i] = brit;
        ledcolor_g[i] = brit;
        ledcolor_b[i] = brit;
    }
	for(int led_i = 0; led_i < 58; led_i++) {

        sprintf(cmd, "echo %d > /sys/class/leds/sunxi_led%dr/brightness", ledcolor_r[led_i], led_i);
        system(cmd);
   
        usleep(100); 
    }
}

然后程序和系统就一起死掉了，只能用reset按钮重启
看上去和论坛里面大伙提到的超过32个灯会出问题一样

那么

现在两个问题
1 是在tina里面怎么同时驱动超过32个灯
2 是那个echo是改变了单个灯的数据，那么能不能一口气把58个数据都准备好，然后给DMA下指令发送呢，因为如果不这么做，效率低到可怕呀

@awwwwa 大佬VE是啥啊，能再具体一点不，谢啦

开屏以后就放个图片有点low啊
能放个GIF之类的动画不，这样加载的时候也不寂寞
各位大佬，有啥解决方案不
最好能像苹果那样放个进度条，那样比较高级

@lansecd 谢啦，我搞定了，那个文件名字不能乱填，但是吧这个全志搞的这个-和_填错了就完蛋，不能乱改

我原先的那个项目编译好了不想去破坏它了，新项目换了个Wi-Fi模块，如何新建个项目啊编译个新的
有木有相关的教程啊
就是在source build/even.sh
然后lunch的时候搞个新板子出来，然后编译个新的工程出来，谢啦

哈咯各位大佬新年好呀

我想问一下谁有移植过LVGL9 的tina里面的那个display的驱动啊

那个lvgl9的FB驱动启动以后640X480的分辨率 D1S居然平均只有15贞，这咋用呢？

同样melis的lvgl9平均能跑45贞以上，tina不至于这么点性能吧
我猜是那个FB驱动的问题，应该没能发挥出d1s的性能，于是就想去官方的lvgl里面去移植个试试，但是官方那个是lvgl8的，我弄进去看试了下，应该还是有些地方要改，不然没法用

哪位大佬有移植过这个display的驱动呀，给lvgl9用的，谢啦

@awwwwa 感谢，哈哈哈，搞定了颜色正常了

@awwwwa 我试试，我只是把整组调换了下，如果能改那么颜色就正常了，melis 里面也一样吗？

原本为了布线方便把R0-R5和B0-B5位置交换了一下
原本以为在软件里面重新映射下位置就能搞定了

没想到软件根本没法改这些线的位置

无论是meils还是tina都没法交换这两组线的定义 config.dex
和uboot 那个dts我全改了一遍，只能关闭某个线的输出，并不能改变那个输出pin的定义，比如Red 0和Blue 0 交换一下，甚至改clk和hs交换一下那个屏幕也能输出，其实就是没改变

哈哈哈哈
这个D1S的pin，居然是没法修改输出定义的，哈哈哈哈

@awwwwa 你这个也是错的，这么写会把所有通道都关掉，而不是指定的那个……

我在tina的网卡驱动中看到了rtl8822cs这个芯片的驱动
这玩意性能足够好了，支持2.4G 5.8G的Wi-Fi

但是melis里面没有这个驱动

那么可以手动把tina里面那个8822的驱动移植过去吗？

看起来和xr829差不太多，都是SDIO接口的

tina能用的话melis应该也可以用吧？

@yuzukitsuru 哪里有最新的版本啊，这个版本太多BUG了，干不过它

@awwwwa 你这个版本是正确的

我这个是Melis4呀

github上面，还有gitee上面都有

具体位置在这

https://github.com/Tina-Linux/d1s-melis/blob/master/ekernel/drivers/hal/source/pwm/hal_pwm.c

这个是官方的吗？

有没有Melis3的官方稳定测试过的版本呀，在哪里可以下？
我要遇到同样BuG了好去找个对比的……

还有这个PWM的测试代码并不全，甚至驱动也是不全的，那个功能就写了一个生成PWM波的，没有中断的，也没有PWM对的，也没有PWM捕获，开发文档也没写清楚这些PWM输出引脚也是受限的，容易被其他功能干扰导致不输出

直接看用户手册直接操作寄存器，比较靠谱……

还有我顺带测试了一下那个Ledc驱动的输出，这玩意基本也是个废柴，输出不稳定，800K的周期，部分是800，部分是833，850，如果只驱动一两个应该没事，驱动数量上去了，就会有各种问题……什么头尾绿，颜色不对……那个参数不能乱改，应该调好的，调别的乱跳的时候就不能保证1和0的周期正确了

这段代码是PWM驱动里面的，这个disable没有用处，也就是PWM并不会停止
所以，这代码我猜应该是没测试过的

感觉这个Meils 4 开发的太快了都来不及测试就上线了

void hal_pwm_enable_controller(uint32_t channel_in)
{
    unsigned long reg_addr = PWM_BASE + PWM_PER;
    uint32_t reg_val;

    reg_val = readl(reg_addr);
    reg_val |= 1 << channel_in;

    writel(reg_val, reg_addr);
}

/************   disable  **************/
void hal_pwm_disable_controller(uint32_t channel_in)
{
    unsigned long reg_val;
    unsigned long reg_addr = PWM_BASE + PWM_PER;

    reg_val = readl(reg_addr);
    reg_val |= 1 << channel_in;

    //reg_val = Ox00;

    writel(reg_val, reg_addr);
}

PER那个使能寄存器是这么描述的

Offset:0x0080 Register Name: PER
Bit Read/Write Default/Hex Description
31:8 / / /
7 R/W 0x0
PWM7_EN
When PWM is enabled, the 16-bit up-counter starts working and 
PWM channel7 is permitted to output PWM waveform.
0: PWM disable
1: PWM enable

看了一下文档，这个里面的这些功能，那个Test并没有全部展示

我想问一下这个里面的第6个功能
支持 PWM 输出和捕捉输入产生中断
这个PWM输出，怎么顺便产生中断呀？

2）支持脉冲（脉冲个数可配）、周期和互补对输出；
（
3）支持捕捉输入；
（
4）带可编程死区发生器，死区时间可控；
（
5）0-24M/100M 输出频率范围、0%-100% 占空比可调、最小分辨率 1/65536；
（
6）支持 PWM 输出和捕捉输入产生中断；
（
7）支持 PWM 组模式，分为 4 组，同组内各个通道起始相位可配置。

各位全志的大佬

就像那个stm的hal定时器一样
在PWM波的上升沿，或者下降沿触发

melis里面定时器我就找到个按时间触发的
那么怎么搞个定时器能按PWM的信号触发呀

我最近想要给D1s扩展出多条WS2812的总线，想用PWM
的方式去输出数据，ledc 貌似只有一条总线，那么是不够用的呀

我想用PWM+DMA去控制ws2812的灯

先讲为什么，这个芯片貌似只有一个LEDC的输出总线，也就是只有一条ws2812的灯串，但是我需要3条，那么PWM输出脚就很多，所以想拿来用一下顺便学一下那个DMA怎么用

感觉加个定时器应该不难

PWM控制用的是下面这个库
hal_pwm.c
我看了一圈有个hal_pwm_control
这个是可以去控制PWM的，也测试成功了
但是想要控制WS2812，这种灯需要直接把PWM的占空比当作01010101这种数据去输出

我的想法是弄个定时器，周期就是800K的时钟周期（按ws2812需要的设置），每一个callback去设置一次占空比，直接用DMA从内存往占空比的那个寄存器写数据，这么搞应该可以吧

无奈这个库里面貌似没有直接改占空比的操作的函数，然后我就想从那个hal_pwm_control，里面扒出来，无奈的是没怎么看明白是怎么操作那个PWM寄存器的
所以想请教一下各位大佬怎么直接改寄存器，配置PWM占空比啊？

我用的是Meils，谢谢啦

}

上次那个Wi-Fi其实也没调完整，在每次启动的时候都会加载个config文件，如果没有就创建一个，但是我看了一下，每一次都没能创建成功
然后我自己写了一段写文件的代码也一样不成功
fopen 返回值是-1
然后也是一样没法写入，用df查看磁盘空间显示0

那么这个
这个UDISK不是用户自定义分区嘛，怎么让他变得可读写啊
还是文件系统的格式不太对，得改这个分区的格式啊？

[partition]
    name         = UDISK
    ;size = flash size - (boot0 + mbr) size - env - env-redund - ROOTFS
    ;8(or 16) * 1024 * 2 - 64 * 2 - 5632 - 8 - 8 - 10240
    size         = 10032
    ;downloadfile = "data_udisk.fex"
    user_type    = 0x8000

系统的这三个选项具体都有啥区别啊
Rootfs Filesystem Type (Allwinner Minfs Filesystem) --->

ARM Littlefs Filesystem
Allwinner Minfs Filesystem
Fat Filesystem

我选中间那个Minfs Filesystem pack才能打包成功，但是系统没法写入了nor Flash还有很大空间，但是df出来，磁盘空间是0，这怎么往nor flash里面读写文件啊

选上面那个ARM的，直接打包不了，提示太大了，16M的打包不了

选FAT那个也是，打包不了报错。。。

如果想要使用nor flash 做可读写磁盘的话怎么配置啊？

[mbr] size = 16 [partition_start] [partition] name = bootA size = 4096 downloadfile = "melis_pkg_nor.fex" user_type = 0x8000 [partition] name = ROOTFS size = 12032 downloadfile = "data_udisk.fex" user_type = 0x8000 [partition] name = UDISK size = 10032 user_type = 0x8000

@nideyida 主要是用的人太少了，现在虽然价格便宜性能好，但是要想全用起来要掉层皮的……好难啊，这芯片有ledc控制器，但是没有一个好用的上层驱动库，不像esp32 的Arduino框架下那个fastled那么好用，要是能移植一个进来就好了

@iincity 我直接把那个大包的判断大小的函数给改了，8M也当16M大包，这就是开源的好处，哈哈哈哈

如题
D1S上面有3个LEDC控制器的输出针 PE5 PF2 PG13
但是我看了一圈ledc那个hal库hal_ledc.c
看起来只能输出一条LED灯的控制总线

这个是那个配置文件里面的内容

LEDC_PIN 就是输出脚
LEDC_PINMUXSEL 就是功能选择
然后这个 LEDC_BASE 只有一个
是不是只能就输出一条WS2812总线的灯啊？

#ifndef __LEDC_SUN8IW20_H__
#define __LEDC_SUN8IW20_H__

#define LEDC_BASE 0x02008000

#define SUNXI_GIC_START 16
#define SUNXI_IRQ_LEDC (52 - SUNXI_GIC_START)

//#define LEDC_PIN	GPIOG(16)

#define LEDC_PIN	GPIOF(2)

//#define LEDC_PINMUXSEL	7
#define LEDC_PINMUXSEL	5

#endif /*__LEDC_SUN8IW20_H__  */

那么如果想要控制多条LED灯总线，应该怎么办呀？
有木有大佬有PWM的输出实例呀，我看了一下PWM的出口很多啊，如果用PWM+定时器+DMA输出的话，就可以做到更多条的LED灯总线了，但是这里面有个关键函数，不知道该怎么写呀

这个里面的 HAL_TIM_PWM_Start_DMA
这个怎么在Melis系统里面实现啊 谢啦各位大佬

我在PACK的时候发现那个img默认是8M的nor，但是吧我板子上面是16M的

因为之前搞wifi要直接塞点文件进去，大包的时候就出错了，说是超过img的大小
然后我才发现一直是8M的，那么怎么修改配置文件，让这个8M变成16M呀

@spr2023 那个melis4 里面有很多个SDIO，SD卡默认是0号，然后wifi是1号，所以不冲突都可以用，只不过想要用这玩意的难度和重新移植一遍没有区别。。。。

@leomini5

我搞定了，过程一言难尽

我发现在那个sys_nor_config.fex 文件里面的Wi-Fi就没配置SDIO，但是也没看到xr829的配置参数，那么这要怎么配置呀大佬，求助呀

@awwwwa 我回去试了，这个ledc还是有问题，fifo模式下就两个灯亮，问题出在那个写入了，数据写的不对，然后DMA模式下还是不亮，我先凑合用吧，现在问题最大的是那个Wi-Fi Xr829 在Melis上没法正常工作……

在melis里面用那个wifi -s扫描网络，报了一堆错误，最后所有程序都结束。。。。

这个Wi-Fi为啥会用到SD卡的东西啊
xradio_load_mac_addr
这个需要往SD卡里面写配置信息？能不能直接往 norflash里面写啊，我准备不用SD卡

求助求助，谢谢啦

我一直想找个2.4G 5G双频的Wi-Fi 模块
这个859A刚好满足要求而且还是支持Wi-Fi 6的
太强大了，那么问题来了，这玩意看起来和xr829差不多，D1s应该也能用这个模块吧，问题是驱动能移植到Melis上或者tina上面嘛

@awwwwa 感谢大佬的关注，我自己解决了

Melis4 Wi-Fi
位置和技术文档里面那个不一样，只能自己想办法

make menuconfig
首先下面这个地方得编译那个Wi-Fi网络的协议栈，没这个没法用的
→ Kernel Setup → Components Support → Thirdparty Components Support → Enable Network Support → Network → Network protocol
-*- lwip
然后嘛就是那个驱动层
按照板子上面的Wi-Fi芯片选，还有那个晶振什么的别选错了，不然也没法用
位置在这里
Kernel Setup → Drivers Setup → net drivers → xradio driver ──

• Enable xradio ctrl
  Xradio chip (Enable xr829 driver) --->
• Use Firmware 40M for XR829
  这两也是必须要的
  一个是Wi-Fi控制器还有一个是驱动
  然后这个里面直接编译会报错，缺了个库里面的东西，说白了就是有个地方东西没编译，导致这个ctrl这里编译不过去，坑啊
  下面这个就是解决的办法
  → Kernel Setup → Drivers Test Sample → Net Work ──────
  wifi loop test
  • wifi tcpip test
    wifi socket test
    这个选项会编译
    ekernel/drivers/test/network/tcpip/tcpip_adapter.h
    ekernel/drivers/test/network/tcpip/tcpip_adapter.c
    哎。这玩意放test里面，我一顿好找。。。。。。。。。。。。。。。。。。
    中间那个必须选上，不然上面那个ctrl编译不过去
    然后嘛，我这就编译成功了
    text data bss dec hex filename
    3629384 93624 4039056 7762064 767090 ekernel/melis30.elf
    pack melis

make completed successfully (37 seconds)

但是，我还没有烧到板子上测试那个Wi-Fi到底行不行，所以嘛。。。。。我也不知道到底行不行，反正那个ctrl里面有连Wi-Fi用的东西，但愿能用吧

@awwwwa 谢啦谢啦

@xiaowenge 太需要工程师训场啦，这个D1s不像esp32那么简单了，要是能像它那么简单就好啦，其实我也不想去调那些硬件，有个稳定的平台，开发上层应用才好玩啊，底层硬件还有Linux平台，基本上就劝退了一大半人了

哈咯各位大佬
我用的是哪吒那个D1s的开发版，用的Xr829
谁知道这里面那个Wi-Fi 具体怎么用的呀？

Tina里面的Wi-Fi 测试我试过了，没问题

现在是在melis 系统里面，那个Wi-Fi 我编译了那个第三方的库，里面有ping之类的测试应用，那些应用看起来都编译成功了，除了部分有问题的

然后去处理驱动部分的时候遇到个大问题

--- xradio driver │ │

│ │ Xradio chip (Enable xr829 driver) ---> │ │
│ │ [*] Use Firmware 40M for XR829 │ │

这个里面第一个选项是xradio 里面用于控制Wi-Fi 设备的功能，但是吧不能Enable ，不然编译不过去，报的错，没法看懂，那个Wi-Fi manager 也在这个ctrl 里面，如果不编译这个，感觉Wi-Fi 没法启动了

第二个选项就是那个xr829的驱动

能编译成功，但是这个库里面，没看到源码，也没看到测试代码在哪里。

所以问题来了，这个40M库的Wi-Fi 如何初始化，如何启动呢……

谢谢啦

@whycanservice 那melis4 怎么办呀，大佬

@awwwwa 大佬这个驱动文件是tina里面用的还是Meils啊

我这边用的是meils4里面的
hal_ledc
那个驱动

./ekernel/drivers/hal/source/ledc/hal_ledc.c

测试的是这段代码被我改了强行用cpu模式或者是DMA模式测试
CPU部分没问题可以驱动

但是DMA部分不行

具体是哪里的BUG呀大佬，可以指点一下不,谢啦谢啦

各位大佬有谁用过D1S的Ledc驱动器啊，我用的是Meils4
，在测试Ledc驱动器的时候，这个ledc有两种模式，一个是CPU，一个是DMA

灯用的是ws2812
CPU驱动模式一下，Led可以亮但是，那个刷新LED数据比较快的情况下LED头尾的灯颜色就不正常了，最短间隔150ms，这个速度想要做点多灯的驱动肯定不行
于是修改了led的配置参数，我把那个wait data那个时间修改后，就可以刷更快了，但是具体那个时许参数是什么作用呢？

然后还有个问题那个Ledc换了DMA模式以后就直接全黑了，没输出了，这又是为啥啊，没有DMA，全靠cpu的话没法用啊……

哈咯各位大佬，那个Melis4里面的subsys 在哪里呀，没有协议栈可以用wifi 嘛？
还有那些测试应用也没有，怎么办
我用的是哪吒的板子，D1S 上面有个xr829的wifi 芯片，用tina测试连接成功没有问题
但是Melis 4的Wi-Fi 怎么用呀？
