Esp32-c6 1.47 serial monitor

[tom321]

Hi After uploading the code serial monitor is blank, why is that ?

void setup() {
  // initialize serial communication at 115200 bits per second:
  Serial.begin(115200);

  //set the resolution to 12 bits (0-4095)
  analogReadResolution(12);
}

void loop() {
  // read the analog / millivolts value for pin 2:
  int analogValue = analogRead(2);
  int analogVolts = analogReadMilliVolts(2);

  // print out the values you read:
  Serial.printf("ADC analog value = %d\n", analogValue);
  Serial.printf("ADC millivolts value = %d\n", analogVolts);

  delay(100);  // delay in between reads for clear read from serial
}

may need to enable the serial monitor so
after Tools>Board selecting ESP32C6 Dev Board try selecting Tools > USB CDC On Boot > Enabled
recompile and upload program

Thanks, it is working.
Maybe you know a simple code for screen testing ?

what do you mean by screen testing?

Like print on the screen Hello world, I tried this one but can't get it working.

What exactly did you try ?

@tom321

I tried this one but can't get it working

that tutorial is for a
ESP32-C6 Waveshare onboard 1.47 inch 172 x 320 pixels TFT display with an ST7789 driver
it that the TFT display you have? if not give a link to the TFT you are using?

I trying to get something like this but on esp display

[tom321]

I have this one.

@tom321

I trying to get something like this but on esp display

which ESP and TFT display?
the ESP32 can be interfaced with many different TFT displays

[tom321]

ESP32-C6 WiFi 6 and Bluetooth 5.0 USB-C development board integrates...

It looks like the program you referenced in post 5 should work on that ESP32C6/TFT device
what happened when you compiled, linked and uploaded the program?

1. did it compile/link/upload OK?
2. anything on TFT display?
3. anything on serial monitor? e.g. did it go into a reset loop?

post the serial monitor output (as text not a screen image)?

I ot error

there should be details of the error, e.g. messages such as

the code in post 5 uses the TFT_ESPI library which needs the TFT configuration setting up
did you follow the instructions in ESP32_C6_Waveshare_ST7789_Starter
