Hi:

I've just got a STM32F469 Discovery. I want to use it in portrait mode but fail. anybody can help me ?

I'm using 'STM32F4cube // projects // STM32469I-Discovery // Demonstrations //Stemwin'

I've try to modify these

1. in LCDConf.c:

#define LCD_SWAP_XY 1 -> 0

#define XSIZE_PHYS 800 -> 480

#define YSIZE_PHYS 480 -> 800

,

Yes. I have.

in LCDConf.c

♯ define LCD_SWAP_XY 0 , //1

,

♯ define LCD_MIRROR_Y 0 , //1

...

♯ define XSIZE_PHYS 480 //800

,

♯ define YSIZE_PHYS 800 //480

...

♯ define ZONES , , , , , ,2 //4

...

uint8_t pPage[] , , , ,= {0x00, 0x00, 0x03, 0x1F}, /* , ,0 ->, 799 */

...

♯ elif (ZONES == 2 )

,

//{0x00, 0x00, 0x01, 0x8F}, /* 0 ->, 399 */

,

//{0x01, 0x90, 0x03, 0x1F}

,

{0x00, 0x00, 0x00, 0xeF}, /* 0 ->, 239 */

,

{0x00, 0xf0, 0x01, 0xdF} /* 240 ->, 479 */

OTM8009A_Init(OTM8009A_FORMAT_RBG565, LCD_ORIENTATION_PORTRAIT),

in otm8009a.c

if(orientation == OTM8009A_ORIENTATION_LANDSCAPE)

,

{

,

DSI_IO_WriteCmd(0, (uint8_t *)ShortRegData39),

,

DSI_IO_WriteCmd( 4, (uint8_t *)lcdRegData27),

,

DSI_IO_WriteCmd( 4, (uint8_t *)lcdRegData28),

,

}

,

else

,

{

,

DSI_IO_WriteCmd(0, (uint8_t *)ShortRegData39_P),

,

DSI_IO_WriteCmd( 4, (uint8_t *)lcdRegData27_P),

,

DSI_IO_WriteCmd( 4, (uint8_t *)lcdRegData28_P),

,

}

where

const uint8_t lcdRegData27_P[] = {0x00, 0x00, 0x01, 0xDF, OTM8009A_CMD_CASET},

const uint8_t lcdRegData28_P[] = {0x00, 0x00, 0x03, 0x1F, OTM8009A_CMD_PASET},

const uint8_t ShortRegData39_P[] = {OTM8009A_CMD_MADCTR, OTM8009A_MADCTR_MODE_PORTRAIT},

enjoy.

Wow, that was fast.

It works perfect.

Thank You. You are my HERO.:)

Did you changed touchscreen orientation too?
