XIAO ESP32-C3 will not run example sketches

Development Tools Uploading
1

Hi,

I am trying to get some basic control over a XIAO ESP32-C3. I uploaded the board data to my IDE and everything seems to be recognized. I tried to run a basic example sketch for the ESP32 and I get the following results. The error codes seem to be consistent across the sketches I have tried to upload so I believe I have still not gotten all of my settings secured.

I compile and upload the code, but it doesn't quite happen. I do not understand the last line "Hand resetting via reset pin." Can anyone please direct me to that which I am totally missing here>

[code]
/*
 Repeat timer example

 This example shows how to use hardware timer in ESP32. The timer calls onTimer
 function every second. The timer can be stopped with button attached to PIN 0
 (IO0).

 This example code is in the public domain.
 */

// Stop button is attached to PIN 0 (IO0)
#define BTN_STOP_ALARM    0

hw_timer_t * timer = NULL;
volatile SemaphoreHandle_t timerSemaphore;
portMUX_TYPE timerMux = portMUX_INITIALIZER_UNLOCKED;

volatile uint32_t isrCounter = 0;
volatile uint32_t lastIsrAt = 0;

void ARDUINO_ISR_ATTR onTimer(){
  // Increment the counter and set the time of ISR
  portENTER_CRITICAL_ISR(&timerMux);
  isrCounter++;
  lastIsrAt = millis();
  portEXIT_CRITICAL_ISR(&timerMux);
  // Give a semaphore that we can check in the loop
  xSemaphoreGiveFromISR(timerSemaphore, NULL);
  // It is safe to use digitalRead/Write here if you want to toggle an output
}

void setup() {
  Serial.begin(115200);

  // Set BTN_STOP_ALARM to input mode
  pinMode(BTN_STOP_ALARM, INPUT);

  // Create semaphore to inform us when the timer has fired
  timerSemaphore = xSemaphoreCreateBinary();

  // Use 1st timer of 4 (counted from zero).
  // Set 80 divider for prescaler (see ESP32 Technical Reference Manual for more
  // info).
  timer = timerBegin(0, 80, true);

  // Attach onTimer function to our timer.
  timerAttachInterrupt(timer, &onTimer, true);

  // Set alarm to call onTimer function every second (value in microseconds).
  // Repeat the alarm (third parameter)
  timerAlarmWrite(timer, 1000000, true);

  // Start an alarm
  timerAlarmEnable(timer);
}

void loop() {
  // If Timer has fired
  if (xSemaphoreTake(timerSemaphore, 0) == pdTRUE){
    uint32_t isrCount = 0, isrTime = 0;
    // Read the interrupt count and time
    portENTER_CRITICAL(&timerMux);
    isrCount = isrCounter;
    isrTime = lastIsrAt;
    portEXIT_CRITICAL(&timerMux);
    // Print it
    Serial.print("onTimer no. ");
    Serial.print(isrCount);
    Serial.print(" at ");
    Serial.print(isrTime);
    Serial.println(" ms");
  }
  // If button is pressed
  if (digitalRead(BTN_STOP_ALARM) == LOW) {
    // If timer is still running
    if (timer) {
      // Stop and free timer
      timerEnd(timer);
      timer = NULL;
    }
  }
}

What error messages ?

Looks like the program loaded OK ?

Does the program run if you press the reset button ?

Probably easiest to try a simple LED blink ort similar.

Can you tell me what that last line means? The sketch I uploaded isn't the best for demo purposes. I will try a basic blink sketch to see if it works. Thank you, though . . . I thought I was wrong but I might be mistaken.

Not a lot.

If you were using a USB to serial adapter or similar that has has a RTS pin that can be used to reset the Arduino.

youre XIAO ESP32-C3 has 2 bottom , one for Boot and one for Reset.
normaly befor upload codes press Boot & hold , press Reset & hold , ilsen to the Reset Sound form PC , relies Reset , lisen Reset Relies Sound form PC , relies Boot Botton , now upload Code.
for starting the uploadet code in the XIAO ESP32-C3 you have to press short the Reset Bottom .
your Error Screen was showing well the upload procedure .
An XIAO ESP32-C3 has 2 Modi , one for upload the Code , and one for run the code , this is the reason for the bottom prosedure.
