Usage

Click this link to login or signup to mbed
Import the mbed_blinky program
Click the Compile icon of the top toolbar to compile the program, then download a compiled hex file.
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

The latest firmware version for the Arch Max is v0203 built at Oct 8 2014. To check your firmware version and built date, open the MBED.HTM file of your MBED disk in a text editor.
