gpio: gpio_set_level(226): GPIO output gpio_num error

Hello,

I have a problem concerning the writing of the pins. I want to put them to 1 to drive a Multiplexers (MUXO & MUXI in the code below) but when i try to control MUXI, i have the error code in the Serial terminal "E (X) gpio: gpio_set_level(226): GPIO output gpio_num error" and i don't know why there is this problem neither how to fix it.

I didn't really look at your code, but pins 34&35 are input only.
