USB Bootloader for LPC1768-H Blue Board

The JTAG debugger has been working quite well. But it needs a parallel port which most laptops including my own lack. LPC17xx conveniently supports USB device interface which can be used for bootloading. USB is ubiquitous and using it will obviate the need for any extra programming hardware.

Hello World from LPC1768

Finally, the blueboard LPC1768-H arrived. Have a look.

Unfortunately, it did not have accessories like JTAG cable or mini-USB cable. So, a quick visit to the local electronics store was needed. Once the mini-USB cable was plugged into the blueboard, the LED started blinking. Apparently NGX had pre-loaded the board with a test program. Now I had to say "hello world" through the board.

Hobby work on ARM cortex M3

I've been a staunch follower of AVR 8-bit AtMega series of Microcontrollers for hobby works at home. Working with the AtMega line has been pure fun. But the time has finally come where the power of an AtMega can no longer slake my thirst. The next logical step would be to move to a 32-bit controller. The biggest pain in making the move is the absence of a fantastic community like AVRFreaks.
