I developed a battery powered display with inkplate 5 & 5v2. The system is on deep sleep & re-displays the information in a configurable timeperiod.
When the displays gets low on battery, it sends an alert in order to recharge it. I’d like to inform the person who puts it on a charger when this happens, that means the board should wake up when an external power supply is plugged in, then displays an information that the device is charging.
What I’m not sure: is a wake up in that case possible and is it possible to query the charging state? The device knows it because of the red led.
Hi @achim ,
thanks for your question! I understand the situation, but it’s not possible to wake up in case the display is charging. You can write the user a message on the screen to press the WAKE button or even beter RESET the device by double-pressing the power button once they have connected the charge. It’s an interesting idea to add charging detection to Inkplate though!
