Pin gets pulled HIGH even it is defined LOW. #81

Hi, first of all thanks for your nice piece of software !

I use the ST77XX example to build a new sketch on an ESP32S2.

In the main sketch I have defined a PIN like this : #define ENBST 33 in the setup of my main sketch I use : pinMode(ENBST, OUTPUT); // boost function digitalWrite(ENBST, LOW); // off by default to pull it LOW.

When I flash the Sketch the PIN 33 is always HIGH, even it is not defined or talked to anywhere else in the sketch and all other files as far as I can see. (even searched all the source for "33")

I can use the same sketch without your lib attached and the PIN gets pulled LOW and stays that way.

Whats going on ? Thanks and greetings.

Hello, the Lib use internal no pinMode / digitalWrite functions. When there is something wrong it could only be one of the other libs or some code in the examples like for controling the menu. Are you are using further libs ?

Best Regards,

Hi, thanks for your quick answer on a Sunday afternoon :D !! I just compiled the demo sketch for the st7735 WITHOUT any of my code, I have selected "digital pins" (2) as input method and set the values for my three buttons accordingly (37, 38, 39, ) I have the same issue that pin 33 gets pulled high.... I then added the definition for pin 33 and pulled it low in setup, but it gets pulled high again right after boot. None of my sketch was involved in this test. edit: I use the internal pullups for my buttons and set the method to "active low 1 " but also without this setting 33 gets pulled high.. forgot to mention .
