The problem is that GPIO 34 and 35 are always LOW.
Code: Select all
#define RST_BUTTON 33
#define Input_1 32
#define Input_2 34
#define Input_3 35
pinMode(RST_BUTTON, INPUT);
pinMode(Input_1, INPUT);
pinMode(Input_2, INPUT);
pinMode(Input_3, INPUT);
delay(50);
digitalWrite(RST_BUTTON, HIGH);
digitalWrite(Input_1, HIGH);
digitalWrite(Input_2, HIGH);
digitalWrite(Input_3, HIGH);
delay(50);
I did connect external Pull-up resistors to 34 and 35. They are still always LOW.
Why ?
