More JuiceBox Dev

By vsergeev | Published: January 19, 2006
I’m not entirely new to microcontrollers, although I’ve never been around the ARM ones. Most of my experience comes from the Atmel AVR line of microcontrollers, but I still consider myself a noob. The JuiceBox is a great dev board to learn on. Everything is production prewired, all you have to do is write the code [...]

After writing the game itself for the first time on my computer, I proceeded to clean up some of the LCD Demo Code and then port the Game of Life to the JuiceBox. It uses the whole screen as the grid of cells, and each individual pixel as a cell. The initial grid is randomly [...]

Update on JuiceBox Dev

By vsergeev | Published: January 14, 2006
After frying my last juicebox (long story), I bought another one off ebay and it recently arrived. Finally I have had some time to get it up to speed (open it up, solder the sd/mmc lines, solder the UART lines). It is working great, and for the first time I am seeing the kernel boot [...]

Perf board Wiggler build

By vsergeev | Published: January 14, 2006
Well, I finally got around to building the JTAG Wiggler emulator on a perf board. As with most perf boards, it looks ugly, but the joints are good (I’ve gotten better). Next step is to test it… Since my LPC2148 development board is still enroute for its replacement, I guess I’ll be testing this wiggler [...]
