mbed Online Compiler and LPC800

I have build some of the small LPC800 Breakout Boards.

To program them with the online mbed compiler, the resulting bin files have to be changed with the following command:

arm-none-eabi-objcopy -I binary -O ihex mbed_blink_LPC812.bin mbed_blink_LPC812.hex

The arm compiler toolchain should be installed in your path.

Here a small sample program for blinking an LED:

#include "mbed.h"

DigitalOut LED(P0_0);

int main(int argc, char* argv[]) {
	while(true) {
        LED = !LED;

You can program the resulting hex file with FlashMagic and a USB to serial Adapter.

I use FlashMagic on Windows(inside a virtual machine), because on Mac OS X the installation of XQuartz is required.

and the result:
