Hi,

I have a 32F429I discovery board and I am trying to put it into sleep mode using a call to HAL_PWR_EnterSTOPMode . I believe that this works, but I would also like to turn off the display when doing this.

Is there an easy way to do this?

I'm not sure there is, I remember having a discussion about the back light, pretty sure it can't be turned off. Check the schematic for pin/control options.

I believe that you are right, I cannot find anything in the schematics indicating a control of the back light.

Thanks!
