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

Tina 的镜像打包如何把自己的app塞进去啊？发布在 MR Series
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？

tina 的Ledc驱动长时间运行问题发布在 MR Series
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

T113 wpa 自动联网后，再次联网，带蹦了驱动和系统发布在 MR Series
wifi模组是 rtl8821cs
wpa自动联网没问题，但是用tina的api重新联网后系统崩溃，驱动也挂了这会是什么原因呢？
用那个api联网的话需要先disconnect之前的网络吗？

T113 usb0 acm cdc 无法使用 ttyGS0 直接卡主啦发布在 MR Series
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

给大家介绍种控制ledc驱动器的方法 轻松100fps发布在 MR Series
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
B站演示视频【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

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"); // system(cmd); // usleep(100000); // net 方式往内核发送信息 // 测试颜色 struct color_rgb led_color_test; // led_color_test.r= 1; // led_color_test.g= 1; // led_color_test.b= 1; struct color_hsv color_hsv_test; u_int16_t test_h = 0; color_hsv_test = color_hsv(100, 250, 0); //启动全led检查 check_all_led(sock_fd,nlh,dst_addr); //按键全功能检查 void check_all_led(int sock_fd,struct nlmsghdr * nlh,struct sockaddr_nl dst_addr){ struct color_hsv color_hsv_test; u_int16_t test_h = 0; color_hsv_test = color_hsv(33, 235, 0); //用于提示灯颜色 color_hsv(33, 235, 200); int is_stop=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; test_h++; } if(bright2 > 225) { bright2 = 220; t_flag = 1; usleep(40000); } if(bright2 < 0) { bright2 = 0; //t_flag = 0; 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 { //printf("send ok\n"); } usleep(12000); if(is_stop==1){ 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 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

回复: T113 ledc 驱动bug 长时间运行以后出错发布在 MR Series
@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？ -

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(¤t_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; } -
tina ledc驱动里面的这个 led show怎么用呀发布在 MR Series
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

tina中系统内核的驱动程序中如何使用 共享内存？发布在 MR Series
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': drivers/leds/leds-sunxi.c:1513:8: error: implicit declaration of function 'ftok' [-Werror=implicit-function-declaration] key = ftok("/dev/shm/ledc_shm", 0); ^~~~ drivers/leds/leds-sunxi.c:1514:14: error: implicit declaration of function 'shmget' [-Werror=implicit-function-declaration] shm_id = shmget(key, sizeof(share_data), IPC_CREAT | 0666); ^~~~~~ drivers/leds/leds-sunxi.c:1515:37: error: implicit declaration of function 'shmat' [-Werror=implicit-function-declaration] share_data *shm = (share_data *)shmat(shm_id, NULL, 0); ^~~~~ drivers/leds/leds-sunxi.c:1515:5: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement] share_data *shm = (share_data *)shmat(shm_id, NULL, 0); ^~~~~~~~~~ drivers/leds/leds-sunxi.c:1442:19: warning: unused variable 'SIZE' [-Wunused-variable]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

回复: D1s ledc驱动代码bug，DMA模式无法使用发布在 MR Series
@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>; t1l_ns = <320>; t0h_ns = <300>; t0l_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

回复: D1s ledc驱动代码bug，DMA模式无法使用发布在 MR Series
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……

D1s ledc驱动代码bug，DMA模式无法使用发布在 MR Series
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？

Tina Ledc 无法驱动超过32个灯发布在 MR Series
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 -

回复: Meils的PWM BUG发布在 MR Series
@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

D1s如何实现PWM定时器啊发布在 MR Series
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 -
大佬们，谁知道这个PWM的控制器怎么直接改变占空比啊？发布在 MR Series
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

Melis系统如何让板载的NOR flash 可以被写入？发布在 MR Series
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？

@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

D1S的LEDC控制器可以走多少条LED灯总线？发布在 MR Series
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 -
全志的大佬们求助一个Meils4的简单问题发布在 MR Series
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。。。。

Aw859A这个模块D1s能用不？发布在 MR Series
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 -
回复: D1s 在melis系统里面的Wi-Fi 怎么用呀？发布在 MR Series
@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
- wifi tcpip test
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

D1s 在melis系统里面的Wi-Fi 怎么用呀？发布在 MR Series
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 │ │
Enable xradio ctrl │ │
│ │ Xradio chip (Enable xr829 driver) ---> │ │
│ │ [*] Use Firmware 40M for XR829 │ │
Enable XRADIO ETF Mode │ │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

D1s DMA驱动Ledc 问题发布在 MR Series
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……
