Hi,

I have an issue with my XIAO nRF52840 Sense Plus, this code “runs”:

#define LEDRED        (11u)
#define LEDGREEN        (12u)
#define LEDBLUE        (13u)
void setup() {
  pinMode(LEDRED, OUTPUT);
  pinMode(LEDGREEN, OUTPUT);
  pinMode(LEDBLUE, OUTPUT);
}

void loop() {
  digitalWrite(LEDRED, HIGH);
  delay(100);
  digitalWrite(LEDRED, LOW);
  delay(100);
  digitalWrite(LEDGREEN, HIGH);
  delay(100);
  digitalWrite(LEDGREEN, LOW);
  delay(100);
  digitalWrite(LEDBLUE, HIGH);
  delay(100);
  digitalWrite(LEDBLUE, LOW);
  delay(100);
}

Couple comments about code above:

  • The PIN numbers I’m using are not the ones on the schematic, I found these by try/error,
  • I do verify, then upload, it says it works but then it does not do anything.
  • I then run Sketch → Export Compiled Library
  • I had to download Adafruit_nRF52_Bootloader, go to lib/uf2/utils/ and run: python3 uf2conv.py /Users/albertocole/Documents/Arduino/blink_2/build/Seeeduino.mbed.xiaonRF52840SensePlus/blink_2.ino.hex -c -f 0xADA52840

this process is the only way I’ve found to make this thing run code, and on top of that, when I add Serial stuff to try to debug anything, program wont run. I feel like I’m lost with this, just need to know what’s the best way to program with this, I also tried with circuitpython .uf2 (Seeed Studio XIAO nRF52840 (Sense) Download) and it never changed the drive name to CIRCUITPY, so I’m even wondering if I did something to this board that made it unstable/faulty, is there a way to know that?

Thanks in advance

Hi,

Well, we have tested it with the build in macros, and it seems this USER LED behave as expected.

#include "Adafruit_TinyUSB.h"
#define LEDRED  LED_RED
#define LEDGREEN LED_GREEN
#define LEDBLUE LED_BLUE
void setup() {
  pinMode(LEDRED, OUTPUT);
  pinMode(LEDGREEN, OUTPUT);
  pinMode(LEDBLUE, OUTPUT);
  Serial.begin(115200);
}

void loop() {
  Serial.println("Shiny Red");
  digitalWrite(LEDRED, HIGH);
  delay(1000);
  digitalWrite(LEDRED, LOW);
  delay(1000);
  Serial.println("Bright Green");
  digitalWrite(LEDGREEN, HIGH);
  delay(1000);
  digitalWrite(LEDGREEN, LOW);
  delay(1000);
  Serial.println("Melancholy Blue");
  digitalWrite(LEDBLUE, HIGH);
  delay(1000);
  digitalWrite(LEDBLUE, LOW);
  delay(100);
}

That’s what I get when copying your code.

And if I change it for the non-mbed board, I then get this:

Let me know what options I have

Sorry that I don’t possess a Mac to reproduce this issue, on Windows everything seems to be OK. For your reference:

I made it to run that code on a ubuntu box I setup with UTM, found that there’s no Arduino IDE for ubuntu arm (using a M2 Pro), installed the Arduino legacy one, and I was able to run your code, so def something on mac setups, now, I then do the upload button and it still wont do anything, even by changing your code to use 11,12,13 pins, thx for you help I’ll keep digging.
