looking a bit closer at the document you linked, I think you should be able to control the backlight using the Pi PWM capability, but certainly on/off via any GPIO… guessing more than anything though, without having a thorough read through.
Hi,
thanks for the pointers; I had a further problem with connecting V0, but as per your suggestion, I’ve wired it to PWM and the display is now working. I’ve actually got two of these displays and with a bit of extra wiring with CE0/1 and another pin for RS, I have both screens up and running.
Many thanks,
hum, I don’t understand… I think your chart has some errors in it (I assume all notations are physical and not a hybrid physical/bcm). Did you mean phys 17 rarther than 18 for the LCD supply?
