Hello everyone!

I'm beginner with the ESP32,
I'm trying show values of a 3 pin Photosensitive sensor with the ESP32 DevKitV1 in the monitor serie but in the moment of compile the program and see the monitor serie appear a next message:

error.png (21.53 KiB) Viewed 18458 times

My code is:

int sensorValue;

void setup()
{
Serial.begin(9600); // starts the serial port at 9600
}

void loop()
{
sensorValue = analogRead(25); // read analog input pin D25 of the ESP32
Serial.print(sensorValue, DEC); // prints the value read
Serial.print(" \n"); // prints a space between the numbers
delay(1000); // wait 100ms for next reading
}

I have conected the DO pin on D25 of ESP32 pin, pin GND on the GND and VCC pin on 3v3.

I tried erase the flash with flash_download_tool_3.8.8 without lucky

Thanks.

I'd suggest to first remove all connections and try to run. If this runs, check whether you were using the correct pins.

Erasing the flash is best done with an ESP-IDF tool available in all ESP* frameworks: `esptool.py erase_flash`. (Sometimes helpful also `esptool.py flash_id`).

Thanks for the suggest, i could already fix the problem
