Hardware Overview


  1. Click here to login or signup to mbed
  2. Import the mbed_blinky program
  3. Click the Compile icon of the top toolbar to compile the program, then download a compiled hex file.
  4. Drag-n-drop the downloaded bin file into the mbed disk

You can open main.cpp to change the program. For example, use the following code to blink the LED every 0.1 second

    #include "mbed.h"

DigitalOut led(LED1); // on-board led is connected to D13

int main()
while (true) {
led = !led;


To enable SWD debug or to get debug message through USB Virtual serial, please install a driver from mbed.
