ADC channel selection

[rbrakhya]

I´ve been struggling to change the ADC channel on an ESP32-C3.

I get an ADC value, but only from GPIO0 no matter what i set in analogread() it always reads GPIO0.
I tried two boards to rule out physical damage. Any ideas what can be wrong?




Is there somthing whong in my code? Tried the minimal code to isolate the problem.

Code: Select all

void setup() {
Serial.begin(115200);
pinMode(0, INPUT_PULLUP);
pinMode(1, INPUT_PULLUP);

}

void loop() {
  Serial.print("Batt=");
  delay(5);
   Serial.print(analogRead(0));
   delay(5);
     Serial.print("  Solar=");
    delay(5);
   Serial.println(analogRead(1));
   delay(185);
}

Did try without the pinMode without any success.
