Usage​

  1. Click this link 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 0.1s

#include "mbed.h"

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

int main()
{
    while (true) {
        led = !led;
        wait(0.1);
    }
}

Debug​

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

Update or Restore Firmware​
