VS Electronics and Embedded Development

Shortly after I got my JTAG Wiggler working with the JuiceBox, I hunted out some homebrew code precompiled for the JuiceBox. I found it here: http://www.elinux.org/wiki/JuiceBoxCodeTest

Using OCD Commander you can easily upload the code to the processor’s memory through a JTAG emulator, and it will automatically set the PC register to the start of the program. All you have to do is hit go, and your program is running.

I played with the LCD demos, and modified the second one to print a greeting message, which I took a picture of to post here:

My next familiarization project is to port, for the first time ever, the game of life to the JuiceBox. I will have pictures of this tomorrow when the project is complete. It shouldn’t be too difficult, since the LCD demo code has shows how to drive the LCD and plot pixels.

In addition, I want to mess with the buttons. They are located on PORTG, but I still have yet to learn how I am supposed to properly manipulate the PORT registers on this ARM chip…

I love JTAG and $15 ARM development boards.
