ADC1 GPIO 32/32 and ADC2 GPIO 13/15 difference?
Posted: Sat Oct 10, 2020 7:50 am
we desigin a dev board using ESP32 WROOM-32D, we found the same input sensor（AD） 32& 33 value are same, 13&15 are same . 32/33 and 13/15 are difference.
same arduino code:
the wifi not enable. just turn on bluetooth.
who know what the difference between ADC1 AND ANDC2 when read the AD value ? thx!
same arduino code:
Code: Select all
...
void setup(){
...
u8g2.drawUTF8(1, 1, String(analogRead(13)).c_str());
u8g2.drawUTF8(1, 15, String(analogRead(15)).c_str());
u8g2.drawUTF8(1, 30, String(analogRead(32)).c_str());
u8g2.drawUTF8(1, 45, String(analogRead(33)).c_str());
...
}
void loop(){
//todo
}
