ESP32S3-Cam实践(OLED表情动画-手搓)

0.参考

OLED 驱动器 SSD1309        十六、OLED实验        STM32第四课：OLED屏幕控制

0.96oled表情动画显示Demo    oled表情    DIY OLED表情    OLED机器人表情

以ESP-IDF v5.5.0 Examples中的I2C OLED example为工程为基础。手搓Cozmo表情

1.显示表情位图

改动1：删除使用lvgl相关的代码，清理成使用esp_lcd_panel的方式。

改动2：使用esp_lcd_panel_draw_bitmap向屏幕输出。

改动3：画正常表情位图、画愤怒表情位图、画恶魔眼表情位图、

static uint8_t expressin_devileye_0[EXAMPLE_LCD_H_RES * EXAMPLE_LCD_V_RES / 8] =
{}
static uint8_t expressin_anger_0[EXAMPLE_LCD_H_RES * EXAMPLE_LCD_V_RES / 8] =
{};
static uint8_t expressin_normal_0[EXAMPLE_LCD_H_RES * EXAMPLE_LCD_V_RES / 8] =
{};

改动4：主程序中循环显示三种表情

while(1) {
        do_expression_normal(panel_handle);
        vTaskDelay(2000 / portTICK_PERIOD_MS);

        do_expression_anger(panel_handle);
        vTaskDelay(2000 / portTICK_PERIOD_MS);

        do_expression_devileye(panel_handle);
        vTaskDelay(2000 / portTICK_PERIOD_MS);
}

OLED显示

2.显示表情动图

改动5：正常的Cozmo表情

static void do_expression_normal(esp_lcd_panel_handle_t panel_handle)
{
    uint8_t buffer[EXAMPLE_LCD_H_RES * EXAMPLE_LCD_V_RES / 8];

    memcpy(buffer, expressin_cozmo_0, sizeof(expressin_cozmo_0));
    esp_lcd_panel_draw_bitmap(panel_handle, 0, 0, EXAMPLE_LCD_H_RES, EXAMPLE_LCD_V_RES, buffer);
    vTaskDelay(3000 / portTICK_PERIOD_MS);

    ////Draw Blink...

    esp_lcd_panel_draw_bitmap(panel_handle, 0, 0, EXAMPLE_LCD_H_RES, EXAMPLE_LCD_V_RES, buffer);
    vTaskDelay(200 / portTICK_PERIOD_MS);
    memcpy(buffer, expressin_cozmo_0, sizeof(expressin_cozmo_0));
    esp_lcd_panel_draw_bitmap(panel_handle, 0, 0, EXAMPLE_LCD_H_RES, EXAMPLE_LCD_V_RES, buffer);
}

改动6：类Cozmo表情左看

static void do_expression_lookleft(esp_lcd_panel_handle_t panel_handle)
{
    uint8_t buffer[EXAMPLE_LCD_H_RES * EXAMPLE_LCD_V_RES / 8];

    memcpy(buffer, expressin_cozmo_0, sizeof(expressin_cozmo_0));
    esp_lcd_panel_draw_bitmap(panel_handle, 0, 0, EXAMPLE_LCD_H_RES, EXAMPLE_LCD_V_RES, buffer);
    vTaskDelay(1000 / portTICK_PERIOD_MS);

    ////Draw Last Frame...

    esp_lcd_panel_draw_bitmap(panel_handle, 0, 0, EXAMPLE_LCD_H_RES, EXAMPLE_LCD_V_RES, buffer);
}

改动7：类Cozmo表情右看

static void do_expression_lookright(esp_lcd_panel_handle_t panel_handle)
{
    uint8_t buffer[EXAMPLE_LCD_H_RES * EXAMPLE_LCD_V_RES / 8];

    memcpy(buffer, expressin_cozmo_0, sizeof(expressin_cozmo_0));
    esp_lcd_panel_draw_bitmap(panel_handle, 0, 0, EXAMPLE_LCD_H_RES, EXAMPLE_LCD_V_RES, buffer);
    vTaskDelay(1000 / portTICK_PERIOD_MS);

    ////Draw Last Frame...

    esp_lcd_panel_draw_bitmap(panel_handle, 0, 0, EXAMPLE_LCD_H_RES, EXAMPLE_LCD_V_RES, buffer);
}

改动8：主程序中循环显示三种表情

while(1) {
        do_expression_normal(panel_handle);
        vTaskDelay(2000 / portTICK_PERIOD_MS);

        do_expression_lookleft(panel_handle);
        vTaskDelay(2000 / portTICK_PERIOD_MS);

        do_expression_lookright(panel_handle);
        vTaskDelay(2000 / portTICK_PERIOD_MS);
}

OLED显示，通过增加表情帧率实现流畅效果。
