Thanks Felix,

That helped. I guess from the documentation I thought that just adding the M5StickCPlus library would work. I have verified that some other programs do work (Display, TFT_Clock, PowerWake) with adjustments for the larger display size.

The AXP192 and I2C_Tester programs work with your changes although I left Wire.begin() at default because I was checking the bus on the Grove port and that now is working.

I did notice that on the Plus there is a small current draw on the battery (-0.5 mA) when I am running on USB power but it is 0mA on the StickC.

I'm having a real basic issue programming the M5StickCPlus. I am using the M5StickCPlus library but the only program that works correctly so far is the FactoryTest.ino.

I tried using AXP192.ino and I got the following error:
M5StickCPlus_AXP192:38:16: error: 'class AXP192' has no member named 'SetLDO3'
M5.Axp.SetLDO3(false);

I did #include <M5StickCPlus.h>

I also tried I2C_Tester.ino and it runs if I don't have any external I2C devices, but if I add an I2C device in the Grove port - the Display no longer works.

Is there something else that I need to do besides changing the library reference to use M5StickC programs with the Plus?

If you are using a Grove ToF from Seeed there are pads to add a two pin header for the Xshutdown input and Interrupt output pins. You can use another GPIO to disable the first ToF while you program the second one to a different address. You do have to reprogram it every time you power up. Probably just easier to get the PaHUB.

I just got an M5Stack Fire and when I upload example programs they do not run unless I unplug the USB cable. Is that normal?

The last message in the upload window is:
Leaving...
Hard resetting via RTS pin...

Is it possible that isn't working? Pressing the power button doesn't fix it either, only unplugging the USB cable.
