ДРузья, есть у меня китайская платка с STM32F103 и дисплеем ili9320
Есть примеры вывода картинок из флеша контроллера.
Вот функция:
void LCD_WriteBMP(uint8_t Xpos, uint16_t Ypos, uint8_t Height, uint16_t Width, uint16_t *bitmap)
{
uint32_t index;
uint32_t size = Height * Width;
uint16_t *bitmap_ptr = (uint16_t *)bitmap;
LCD_SetDisplayWindow(Xpos, Ypos, Width-1, Height-1);
//LCD_WriteReg(0x03, 0x1038); //Из№ыРиТЄєбПтПФКѕНјЖ¬Ј¬Ѕ«ґЛИҐµфЖБ±О Ј¬Н¬К±Ѕ«WidthєНHightµч»»Т»ПВѕНїЙТФ
LCD_WriteRAM_Prepare();
for(index = 0; index < size; index++)
{
Write_Dat(*bitmap_ptr++);
}
//»Цёґґ°МеґуРЎ
LCD_WriteReg(R80, 0x0000); //Л®ЖЅ·ЅПтGRAMЖрКјµШЦ·
LCD_WriteReg(R81, 0x00EF); //Л®ЖЅ·ЅПтGRAMЅбКшµШЦ·
LCD_WriteReg(R82, 0x0000); //ґ№Ц±·ЅПтGRAMЖрКјµШЦ·
LCD_WriteReg(R83, 0x013F); //ґ№Ц±·ЅПтGRAMЅбКшµШЦ·
}
Однако, когда я ввожу в качестве картинки массив вида 0xF800, 0xF800, 0xF800, 0xF800, (красные точки), вместо этого диспле рисует одну красную, 2 черных, далее снова одну красную.
В чем может быть дело?
Ну и вот инициализация:
void LCD_Init(void)
{
static uint16_t DeviceCode;
LCD_Configuration();
LCD_WriteReg(0x0000,0x0001);
LCD_Delay(5); // LCD_Delay 50 ms
DeviceCode = LCD_ReadReg(0x0000);
printf(" ID=0x%x\n",DeviceCode);
