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

@VK3AWA_1
have you tried compile example programs? are you able to post your codes?

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

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
Felix

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.

@kuriko UIFlow2 has blocks available for UTP control but as UIFlow is built on micropython, NTP is available in the background code functions.

@cyber7
NTP is only availible at M5Burner flashing UiFlow2 firmware
there is no NTP blocky in UiFlow2

Hello @RadghKris

I think it might help to include epdiy.h before Unified.h in your code. E.g.

#include <epdiy.h>
#include <M5Unified.h>

Please see this post.

And maybe also check this documentation - Section 6.Program Compilation & Burning.

Thanks
Felix

Hello @drbob

my example should give you a head start. Please have a look here.

Thanks

Hello @rammelsberg

well, there is an I2C address conflict between M5CoreS3 Touch and M5GoPlus2 as both use I2C address 0x38.

Interestingly when I use M5CoreS3 with M5GoPlus2 in UIFlow2 I can control a servo and use the touch screen. However this is only true for servo 1,2 and 4. When I try to use servo 3 the system locks up.

Note: I have not tried to control DC motors.

So I'd expect some issues and do not recommend to use M5GoPlus2 with M5CoreS3.

Thanks
Felix
