@NiktoI you need to use m5burner to erase the firmware to burn new firmware.
You also need to put the cardputer into firmware mode.

RE: Android sketch works with AXP192, but not 2101
Hello @Krmiller
have you tried
getType()
to determine the correct AXP? See here.For AXP2101 you could try
getVBUSVoltage
. See here.Thanks

RE: M5Unit-8Encoder only for ESP32?
Hello @iainmac
you probably need to adjust the GPIOs used for I2C. You can find the GPIOs M5Dial uses for port A here. (Section HY2.0-4P)
Thanks

RE: PAHub revival
Hello @DR_Froggy_rD
I am afraid that doesn't work. A PaHub is for i2C devices (red Grove connector); the PDM unit is an I2S device (white Grove connector).
BTW: that is the reason in UIFlow2 PaHub doesn't show as option when the PDM unit selected.
Thanks

RE: Bar graph demo application is running extremely slowly on Paper S3
@mwwalker
PaperS3 do have a slow refresh rate. maybe the BarGraph demo isn't very suitable for test, you should try the rtc example: https://docs.m5stack.com/en/arduino/m5papers3/rtc -
RE: ADUINO compile error core2
@VK3AWA_1
have you tried compile example programs? are you able to post your codes? -
RE: CoreS3 and Goplus2
Hello @rammelsberg
I don't see solder jumpers and I cannot find the source code for the firmware running in M5GoPlus2 so no, I don't think you can easily modify the I2C address.
Thanks

RE: LoRa (433 old) LoRa V1.1
Hello @s1y99
ok, now I understand - thank you for clarifying about the closed source M5Core firmware.
BTW: for RST and IRQ you could set no jumper and then solder a wire each to the desired GPIO on the M5Stack bus connector.
Thanks

RE: LoRa (433 old) LoRa V1.1
Hello @s1y99
I am confused. Your own firmware, the one you write for your M5Core (which talks to the LoRa module), is closed source? How come? Are you not writing your own firmware?
I already wrote that it is not possible to jumper LoRa V1.1 the same as the older one, please see my previous post.
MOSI, MISO, SCK and CS/NSS can be setup to use the same GPIOs, however RST and IRQ cannot be jumpered to be the same.
So in conclusion: If for whatever reason the firmware running on M5Core (controlling the LoRa module) cannot be modified then it is not possible to substitute the older LoRa module with the new one.
Thanks
Felix
