hello I have problem to landscape the screen
1.I tried to switch
#define TEST_LCD_SPI_H_RES (320)
#define TEST_LCD_SPI_V_RES (480)
// #define TEST_LCD_SPI_H_RES (480)
// #define TEST_LCD_SPI_V_RES (320)
- //{0x36, (uint8_t ){0x00}, 1, 0}, // Normal 0 degree
//{0x36, (uint8_t ){0xC0}, 1, 0}, // 180
//{0x36, (uint8_t ){0xA0}, 1, 0}, //-270 clockwise 90 counte rclockwise
{0x36, (uint8_t ){0x60}, 1, 0}, // -90 clockwise
3.//ESP_ERROR_CHECK(esp_lcd_panel_swap_xy(panel_handle, true)); - this make me black screen
