I have a Stm32f469 demoboard with a touchescrenn.
It's working nice with Flowcode 7.
I use the board with LIPO (lithium polymer akku)
For testing purposes and measurements, I use a HP Labor Powersupply, where I see the power consumption.
On 4.0 Volt it's using 350mA!
I am looking for many good ideas to save power
The first thing I have changed is the background lighting turn off when I don't use the screen
For that I have taken the R117 out and soldered this on position R119. With the port A3 I controle the light
