Hi Ben
FC9 and M5Stack Core2 works nice together.
On/off button and Display is working fine in the testprogram.
But something with the I2C (just the read) is not working anymore.
It's shows always 255 in the display for each register. (This was working 3 month ago)
I'm not sure if I did something wrong.
regards
Stefan

Re: ESP32 M5 Core2 I2C read problem
Hi Ben
I now know what I did last time.
The last time I used some pin from the extension connector. I removed the cover from the connector.
On this cover is unfortunately a mpu6886.
Today, the test was with the cover and I think the mpu6886 give this problem.
So I removed this connecter and reading from the AXP192 (I2C) is ok again.
I will have a look, why the mpu6886 make trouble.
I attached a picture from the cover and connector.
regards and sorry
