Seeeduino XIAO keyboard emulatingr keyboard

antoniojteixeira · July 19, 2020, 6:37am

Hi everyone,

I am trying to start to use seeeduino XIAO as a keyboard emulator.
The first time I sent the sketch to the XIAO everything was working fine.
I changed the sketch (minor change) and after that I cant no more upload a sketch. The port is detected but when trying to upload the ide says that the port was not found.
The sketch I originally uploaded is the next:

#include “Keyboard.h”

int buttonNum[5] = {3, 4, 2, 0, 1};
char KeySelected[5] = {‘a’, ‘b’, ‘c’, ‘d’ , ‘e’};
int buttSelect = 0;

void setup() {

Serial.begin(115200);
for (int x = 0; x < 5; x++) {
pinMode(buttonNum[x], INPUT_PULLUP);
}

Keyboard.begin();
}

void loop() {

int pressed = HIGH;
for (int x = 0; x < 5; x++) {
pressed = digitalRead(x);
if (pressed == LOW)
{
Keyboard.press(KeySelected[x]);
delay(50);
Keyboard.releaseAll();
delay(50);
pressed = -1;
}
delay(25);
}
}

The error that I am getting is:

Hi @antoniojteixeira , Is this error occurred only when compiling the specific code or any code?

Baozhu · July 20, 2020, 1:56am

@antoniojteixeira How about trying it once?

antoniojteixeira · July 20, 2020, 8:32am

Hi @salman ,

That happens with all code I ry in the XIAO.

Hi Baozhu,

Sory but I didnt understand what you mean.

Can you try to reset the XIAO before uploading the sketch, it might be stuck in the HID Mode!

To Reset

Connect the Seeeduino XIAO to your computer.
Use tweezers or short lines to short the RST pins in the diagram twice.
The orange LED lights flicker on and light up.

At this point, the chip enters Bootloader mode and the burn port appears again. Because the samd21 chip has two partitions, one is the Bootloader and the other is the user program. The product will burn a bootloader code in the system memory when it leaves the factory. We can switch modes with a quick reset.
