填坑之简单粗暴构建lvgl编译环境
以跑了一个lvgl 时钟demo为例,源程序来自韦东山大佬~~~
附件是代码,直接解压替换lv_examples 目录。mno lv_examples即可
这里也给一个简单粗暴写点lvgl建议:
直接在 platform/thirdparty/gui/lvgl-8/lv_examples/src/目录添加自己代码,然后修改main.c, 编译目录在out/v853/vision/openwrt/build_dir/target/lv_examples/src/目录。
具体可以diff一下新旧目录。
lv_examples.tgz
最后是效果~~撒花完结~

持续填坑中:
如果需要自己编译驱动,或是应用,可以参考这个命令:
make -j4 ARCH=riscv CROSS_COMPILE=/home/soso/D1/out/d1-mangopi_mq_rgb800x480_gt9xx/staging_dir/toolchain/bin/riscv64-unknown-linux-gnu- KSRC=/home/soso/D1/out/d1-mangopi_mq_rgb800x480_gt9xx/compile_dir/target/linux-d1-mangopi_mq_rgb800x480_gt9xx/linux-5.4.61/以上命令是d1s,编译wifi驱动。可以看到tina的交叉编译器,内核目录存放规律~~

目前调整了时序,能正常显示,但是有明显的波纹。屏厂家建议是修改clk极性。但是在dts里面还没找到配置。非sync_polarity以及clk_phase.这clk极性是指哪个配置?

回复: 【V853开发板试用】V853开发板填坑记发布在 V Series
二、填坑之spi
1.背景
受限于开发板引出io不是很理想,暂时先用麻雀d1s试了一把spi,并能正常显示图片。目前使用spi1进行驱动。如果是spi0,直接按照帖子中的参考帖子配置即可。具体调试过程:https://bbs.aw-ol.com/topic/1657/麻雀-d1s-spi-tft-开坑/24?_=16571542363882.解决方法:
a.dts spi1_pins_a: spi1@0 { pins = "PD11", "PD12"; /* clk, mosi */ function = "spi1"; drive-strength = <10>; }; spi1_pins_b: spi1@1 { pins = "PD10" ; function = "spi1"; drive-strength = <10>; bias-pull-up; /* cs */ }; &spi1 { clock-frequency = <100000000>; pinctrl-0 = <&spi1_pins_a &spi1_pins_b>; pinctrl-names = "default";/*原贴少了这个配置*/ status = "okay"; st7789v@0 { status = "okay"; compatible = "sitronix,st7789v"; reg = <0>; spi-max-frequency = <32000000>; rotate = <90>; rgb; fps = <30>; buswidth = <8>; reset = <&pio PD 13 GPIO_ACTIVE_LOW>; dc = <&pio PD 14 GPIO_ACTIVE_LOW>; led = <&pio PD 15 GPIO_ACTIVE_HIGH>; debug = <1>; }; };另外需要按照帖子中大神的回复,修改spi1的地址大小。如果图片显示异常,或是显示不全,请修改便宜。240*280,y偏移20,x不用便宜即可。至于这个值怎么查出来,卖个关子~~
3.留坑
目前能正常显示图片,但是播放视频直接退出。可能需要设置缩放。这个后续验证后再续楼。4.最后,有图有真像

麻雀 d1s,又又开新坑之7701s发布在 MR Series
前期工作:
1.使用荔枝派d1的驱动,包含dts以及驱动,仅改linux部分,uboot部分没有修改;
2.关闭uboot的lcd驱动
3.目前已经能显示,但是显示的图像变成“双屏”。spi的初始化已经在树莓派上验证过。能正常显示。应该是全志平台哪里配置不对。
目前尝试:
a.关闭uboot的lcd驱动,修改uboot的lcd的配置,将分辨率调成一致,问题依旧
b.目前这个方屏跟荔枝派不是一个型号。但是都是7701s。480*480.以下是lcd的dts

tf卡启动,没有修改到tf卡相关。只是添加了spi和改了你说的寄存器范围。刚才spi的dts错误的话,还能识别到。看日志好像现在是识别不到tf卡。初步判断,有可能是io口引用冲突导致。这边有个疑问,d1s少了部分io。那么io计算方法是否还是和d1一致,也是按照每个pin有多少个做偏移,还是按照固定的io数去计算

【保姆级教程】全志V853开发板硬件指南
1.即将使用的硬件:
a.摄像头。做简单识别,根据人脸识别不同人,显示不同表情或是动作
b.串口,调试用
c.wifi模块,联网用。这年头,没网络你别跟我说其他~~
d.声卡,麦克风,主要完成录音,语音识别以及播放音频。
e.pwm控制舵机,期望值是驱动机械,暂定是微型坦克
f.spi tft,可以显示摄像头以及做一些表情按照保姆级教程, 结合上述硬件需求
a. 先上电,看串口输出情况,以及登录到系统看看,接线如下,波特率115200

b.通过adb连接,下载adb https://www.aw-ol.com/downloads?cat=5
可以打开各种软件管家,就能安装驱动,驱动识别成功后,即可。如果不烧系统,用adb,控制,和上传足矣~~c.联网
root@TinaLinux:/# wifi -o sta root@TinaLinux:/# wifi -c awol 12345678然后就可以
ifconfig看到wlan0上有ip,可以愉快ping www.baidu.com
惊奇发现有iperf,后面打流看看
python居然没有带,蛋蛋的忧伤,看来编译sdk是跑不掉。。。d.其他
lv_examples没找到。。。有可能出厂固件可能不是最新,看来烧固件是接下来要搞的~~~问题:仅仅从固件层面,简单测试发现问题,需要进一步核实以及查找原因。 摄像头图像颜色偏浅 ,默认固件没有lvgl例子,无法控制lcd,从event0没有获取到触摸数据,测试df_andi报错,报错如下:

麻雀 d1s spi tft 开坑发布在 MR Series
手上有个st7789的屏,开坑,驱动这个屏,目前spi0引出到spi flash,空间比较小。不好飞线。考虑使用gpio模拟或是spi1.有使用经验的朋友可以交流一下

回复: D1s + Toshiba LTPS 3.5寸 RGB888屏 安排上了发布在 MR Series
@whycan 看d1s好像只有18个io接666,888的话,PD口好像不够吧。可以怎么连接~
不要在意这些细节。哈哈
