Hi everyone.
The TTGO sketch from: THAT Project, works but got error need help please.
Thanks

It either works or you got an error

It can't be both

Ya, sorry my description.
it is working.
got: E (35) gpio: gpio_set_level(226): GPIO output gpio_num error when I reset it, what this meaning?
Thanks

4

any idea for this please.
Thanks.

Since you're seeing the output from the early boot stages of the board, it's not even clear to me that the error is caused by your code. Do you get the same error if you upload one of the known-good examples? Does your sketch work?

It's unfortunate but not uncommon for startup code to be "generalized" to the point where it has incorrect initializations for specific boards...

Thanks.
The board and other code works well, even this Tetris game play well, but got the error when pressed reset button, and got this for any button, I linked a button on 37, and got print of:

......
E (2236) gpio: gpio_set_level(226): GPIO output gpio_num error

What "board" do you have selected?
One possibility is that you're using a pin number that "doesn't exist" on that board, causing the translation of "pin" to internal data to pick up random values...
(For instance, using pin 37 on a board like, say, "Microduino-esp32", which only thinks that there are 22 digital pins.)

Thanks.
I used TTGO T-DISPLAY and selected: TTGO LoRa32 OLE.
the pin 37 works on the board which tested in other code.

Which board EXACTLY? Post a link to it.

Where in the code you posted is Pin 37 used?

The error comes from here:
