Contrast

Open SISLANGER opened this issue 5 years ago • 2 comments

Is it possible to change the contrast of the TFT lcd via firmware ?

What colour profile is being used for the screen. For example sRGB ?

Thank you for your help

void set_brightness(u8 pwm)
{        
    // set brightness
    LCD_WR_REG(0x51); 
    LCD_WR_DATA(pwm*2.55);
    Delay_ms(120);

    // set brightness control
    LCD_WR_REG(0x53); 
    LCD_WR_DATA(0x2C);
    Delay_ms(120);   
}

It doesn't work. I don't know is't hardware or software problem.
