用的是ESP32-S3-DevKitC-1开发板
代码如下 #include #include #include "unity.h" #include "test_utils.h" #include "esp_rgb_lcd_panel.h" #include "esp_lcd_panel_ops.h" #include "soc/soc_caps.h" #define TEST_LCD_H_RES (480) #define TEST_LCD_V_RES (272) #define TEST_LCD_VSYNC_GPIO (42) #define TEST_LCD_HSYNC_GPIO (4) #define TEST_LCD_DE_GPIO (2) #define TEST_LCD_PCLK_GPIO (5) #define TEST_LCD_DATA0_GPIO (37) // B0 #define TEST_LCD_DATA1_GPIO (16) // B1 #define TEST_LCD_DATA2_GPIO (38) // B2 #define TEST_LCD_DATA3_GPIO (15) // B3 #define TEST_LCD_DATA4_GPIO (39) // B4 #define TEST_LCD_DATA5_GPIO (45) // G0 #define TEST_LCD_DATA6_GPIO (3) // G1 #define TEST_LCD_DATA7_GPIO (0) // G2 #define TEST_LCD_DATA8_GPIO (8) // G3 #define TEST_LCD_DATA9_GPIO (35) // G4 #define TEST_LCD_DATA10_GPIO (18) // G5 #define TEST_LCD_DATA11_GPIO (20) // R0 #define TEST_LCD_DATA12_GPIO (14) // R1 #define TEST_LCD_DATA13_GPIO (21) // R2 #define TEST_LCD_DATA14_GPIO (13) // R3 #define TEST_LCD_DATA15_GPIO (47) // R4 #define TEST_LCD_DISP_EN_GPIO (41) void app_main() { #define TEST_IMG_SIZE (100 * 100 * sizeof(uint16_t)) uint8_t *img = malloc(TEST_IMG_SIZE); TEST_ASSERT_NOT_NULL(img); esp_lcd_panel_handle_t panel_handle = NULL; esp_lcd_rgb_panel_config_t panel_config = { .data_width = 16, .disp_gpio_num = TEST_LCD_DISP_EN_GPIO, .pclk_gpio_num = TEST_LCD_PCLK_GPIO, .vsync_gpio_num = TEST_LCD_VSYNC_GPIO, .hsync_gpio_num = TEST_LCD_HSYNC_GPIO, .de_gpio_num = TEST_LCD_DE_GPIO, .data_gpio_nums = { TEST_LCD_DATA0_GPIO, TEST_LCD_DATA1_GPIO, TEST_LCD_DATA2_GPIO, TEST_LCD_DATA3_GPIO, TEST_LCD_DATA4_GPIO, TEST_LCD_DATA5_GPIO, TEST_LCD_DATA6_GPIO, TEST_LCD_DATA7_GPIO, TEST_LCD_DATA8_GPIO, TEST_LCD_DATA9_GPIO, TEST_LCD_DATA10_GPIO, TEST_LCD_DATA11_GPIO, TEST_LCD_DATA12_GPIO, TEST_LCD_DATA13_GPIO, TEST_LCD_DATA14_GPIO, TEST_LCD_DATA15_GPIO, }, .timings = { .pclk_hz = 25000000, .h_res = TEST_LCD_H_RES, .v_res = TEST_LCD_V_RES, .hsync_back_porch = 43, .hsync_front_porch = 4, .hsync_pulse_width = 3, .vsync_back_porch = 12, .vsync_front_porch = 4, .vsync_pulse_width = 2, .flags.de_idle_high = 0, .flags.pclk_idle_low = 1, }, .flags.fb_in_psram = 1, .flags.disp_active_low = 0, }; // Test stream mode and one-off mode for (int i = 0; i < 2; i++) { panel_config.flags.relax_on_idle = i; TEST_ESP_OK(esp_lcd_new_rgb_panel(&panel_config, &panel_handle)); TEST_ESP_OK(esp_lcd_panel_reset(panel_handle)); TEST_ESP_OK(esp_lcd_panel_init(panel_handle)); for (int i = 0; i < 200; i++) { uint8_t color_byte = esp_random() & 0xff; int x_start = esp_random() % (TEST_LCD_H_RES - 100); int y_start = esp_random() % (TEST_LCD_V_RES - 100); memset(img, color_byte, TEST_IMG_SIZE); esp_lcd_panel_draw_bitmap(panel_handle, x_start, y_start, x_start + 100, y_start + 100, img); } TEST_ESP_OK(esp_lcd_panel_del(panel_handle)); } free(img); #undef TEST_IMG_SIZE } 然后是显示器驱动IC的调试文档 用的是IDF4.4,目前显示屏没有任何显示,查了两天没有查出原因,特来请教 |
