Hi guys
I noticed that my M5PaperS3 touch screen is slightly less sensitive when running from battery. Touching the screen with more than one finger helps.
Notes:
Touch wake-up is only possible in ESP light sleep. Please find and example here. Touch wake-up from ESP deep sleep is NOT possible as that would require the touch interrupt line to be connected to a so called RTC GPIO which is not the case in M5PaperS3. Touch wake-up from shutdown mode is NOT possible as the eInk display and touch IC are not running in shutdown mode.Thanks
Felix
