LPC Xpresso from NXP is an extremely cheap ARM development board
In the image above I am using the lpc1114.302 version of the Xpresso development board. I have a few of these Cortex-M0 based boards, a lpc1343 and lpc1768 Cortex-M3 based boards. The lpc1114 boards I got for free from NXP through various promotions they have had recently, the others cost about $30, much cheaper than similar ARM boards from other vendors.
First problem was I changed the working directory for Code Composer Studio, which did not let me compile anything anymore... I re-installed on another machine and finally got it to compile (1 week later).
Next I playing with the grlib demo which is a nice demo showing you the different items shown in the built in library. I tried to change the order of the pages in the demo and made a mistake with a pointer, now it would crash after pressing the next button. It crashed and just sit there beeping.
