ESP32-Video

esp32-video 是从项目 esp_8_bit 移植的esp32-idf组件

Usage

假设你的项目目录如下所示

- YourProject
  - components/
  - main/
  - CMakeLists.txt
  - sdkconfig

1. 将esp32-video添加到你项目的components文件夹中

git submodule add https://github.com/ChisBread/esp32-video components/esp32-video

2. 设置编译优化选项为O2、 默认CPU 频率为240MHz (必要)

idf.py menuconfig

3. 和你现有的图形库(如LVGL)结合使用

Examples

composite_video_lvgl_benchmark

LVGL

Initialize esp32-video

#include "capi_video.h"
//....
void app_main(void) {
    esp32_video_start(0);// PAL
    //esp32_video_start(1);// NTSC
    // do something...
    esp32_video_stop(); // Video output can be turned off and started at runtime
}

LVGL driver

#include "capi_video.h"
//....
static void  lvgl_esp32_video_flush(lv_disp_drv_t * disp_drv, const lv_area_t * area, lv_color_t * color_p) {
    // esp32_video_sync(); // Display is more stable, but more stuttering
    // Set colors one by one
    for(int y = area->y1; y <= area->y2; ++y) {
        for(int x = area->x1; x <= area->x2; ++x) {
            esp32_video_set_color(x, y, lv_color_to8(*color_p));
            ++color_p;
        }
    }
}
