esp32s3接rgb屏幕引脚问题

之前我用过全志f1c接rgb屏幕,采用的是rgb666接法,即接B7-B2,R7-R2,G7-G2,那么rgb565的接法应该是R7-R3,G7-G2,B7-B3,但是我看esp-lcd的test写法,是

Code: Select all

#define TEST_LCD_DATA0_GPIO    (3)  // B0
#define TEST_LCD_DATA1_GPIO    (4)  // B1
#define TEST_LCD_DATA2_GPIO    (5)  // B2
#define TEST_LCD_DATA3_GPIO    (6)  // B3
#define TEST_LCD_DATA4_GPIO    (7)  // B4
#define TEST_LCD_DATA5_GPIO    (8)  // G0
#define TEST_LCD_DATA6_GPIO    (9)  // G1
#define TEST_LCD_DATA7_GPIO    (10) // G2
#define TEST_LCD_DATA8_GPIO    (11) // G3
#define TEST_LCD_DATA9_GPIO    (12) // G4
#define TEST_LCD_DATA10_GPIO   (13) // G5
#define TEST_LCD_DATA11_GPIO   (14) // R0
#define TEST_LCD_DATA12_GPIO   (15) // R1
#define TEST_LCD_DATA13_GPIO   (16) // R2
#define TEST_LCD_DATA14_GPIO   (17) // R3
#define TEST_LCD_DATA15_GPIO   (18) // R4
即B0-B4,G0-G5,R0-R4,和我的认知不大一样,特来请教正确的连接方式是怎样的
下图是我在全志F1c上的原理图
