Hi,

How is it possible to modify the intensity of the backlight when you hack the touchscreen ?
Other question, is it possible to sold the D7 connection with the 5V and the one which is between them ?

Regards,

Alexis

Hi there~

1. No, you can not. I tested it with PWM. It does not work. It only supports on and off.

2. The mid one is the one connected with LCD. The default is VCC. I does not make sure to cut the VCC connection and then  connect to D7 which is connected with VCC. 



Thanks

best rgds
