HX8357_HAL

Hello. I have a problem with hx8357 and bluepill. The display does not work if the frequency of stm32f103c8t6 more than 7 MHz. On 1-7 MHz it's work, but very slowly, if it’s more, the backlight just turns on and nothing happens. What could be the problem?

I modify init, and it's work:

void LCD_Init(void)
{
LCD_RST_S();
HAL_Delay(100);
LCD_Send_Cmd(HX8357_SLPOUT);
HAL_Delay(100);
LCD_Send_Cmd(HX8357_COLMOD);
HAL_Delay(5);
LCD_Send_Dat(0x55);
HAL_Delay(5);
LCD_Send_Cmd(HX8357_DISPON);
HAL_Delay(5);
LCD_Send_Cmd(HX8357_INVON);
HAL_Delay(5);
LCD_Orientation(DEFAULT_ORIENTATION);
HAL_Delay(5);
}
