Hi all,
I want to reduce the power consumption of my M5StickC in deepsleep-mode. When entering the deepsleep via M5.Apx.DeepSleep(10000000); the power drops to about 2mA with LCD turn off using M5.Axp.SetLDO2(false); and
M5.Axp.SetLDO3(false);
With a thermal camera I found out, that the chip next to the display-connection gets hot (see pic) so I think this chip uses at least a part of that 2mA.
Does someone know how to put this chip (name: M5A1 1220) in DeepSleep or what the pinout is to connect its VDD to a GPIO?

Any other suggestions to reduce the deepsleep current?

Thanks
Lukas

Hey

since you pass a pointer to the println-function and the cpu does not know what type of data is located at that position this behaviours seems normal.
In the example in the link they create a structure for the transmitted data. In the callback they copy the recieved data in this structure and later you can print exactly what you want:
