M5PaperS3 wakeup

bletru

Hi everybody,

How do you manage to get maximum battery life?
What's your way to wakeup the module from sleep?
It seems that the touch could not be used to wakeup.
Do you have any other way and if possible with an example?

Thanks in advance for your suggestions and help

I cannot get either to work - when on battery. When on USB power deepsleep does wake up on battery only it doesn't.

Touch interrupt or timer also doesn't seem to work on battery only.

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
