M5Stack Core2 V1.1 Display Problem

[coolj]

hi,
i bought 2 of the new M5Stack Core2 V1.1 and make the same config as the old core2 but the Display stays black.
What can i do, to bring the Display up to work?

I suggest you search the forum, this has been asked before. I think the core2 uses a different display driver.

hi Stuart, the old core2 works perfekt with the M5Stack Tough settings, only the touch-function is not working.
But there is an new core2 v1.1 and this one won't work, because of a missing or wrong startup-sequence.
I think, the AXP192-config is the Problem (no backlight)maybe.

Hi,
looking at the schematics, this module is quite different from the previous one as it is equipped with an AXP2101 power controller chip.
You can try to control this chip using the I2C commands (you can use this code as reference)

Hi Francesco,
is there a way to bring the touch-raw-data to the gui-sequences?

[cicciocb]

No, I think that this is not possible but I could include the support for this module in the future as the touchscreen controller seems to be the same of the M5Tough.

Edit:
sorry, the touchscreen controller is not the same

[coolj]

The touchscreen controller is the FT6336U.
But it's very easy to get the data via i2c.
I buy you a big Coffee if you integrate that Modul

i made little overview-display for my homeassistant and datatransfer on mqtt.
the touch-function to switch the Pages is not guibased but it works for me.
