32F429IDISCOVERY turn off LCD backlight

Question asked by machala.petr on Apr 13, 2015

Is it possible to turn off the backlight of the 32F429IDISCOVERY LCD? I did not realized it until I started dealing with power consumption... I switch MCU to standby mode which is great but LCD is still shining unnecessarily...

I am not able to turn it off... Its probably a HW problem but I am surprised that it just cannot be switched off...ILI9341 supports brightness commands but it doesn't work either...
