Here is the video demoing the motor controller. I used a Mr.Basic robot platform and included a little review about that platform. Code is found after the break.
Demo Platform for the Low Voltage Motor Driver Video!

ISR PWM Code for Motor Driver Booster Pack
Here is a link to the code’s page.
I will be uploading a video demoing the code. Have to build a tiny robot first.
IEE Flip Propeller Code released V1.0
I finished the code for the demo for the VFD. It uses the 8 bit parallel bus. I am working on the serial bus version to save I/O lines and a MSP-430 C code version.
IEE Flip VFD Working! Test code coming soon.
Today I wrote some code to get the IEE Flip VFD working. It has a fairly simple protocol and only took a bit of tweaking to get it working. I wrote the demo code for my Prop Dev Stick and will be uploading the SPIN code later once I finish the feature set.
After this I will write some C code for the MSP430 LaunchPad and get that working. The screen supports a serial input mode which saves 8 I/O pins but requires more timing. I will try to get that working as well.
IEE FLIP Alphanumeric Display Works!
I picked up some of these really neat VFD alphanumeric displays at a surplus shop while at Maker Faire. After acquiring the datasheet from the manufacture, I decided to test them with the built in test mode. I have already started writing the code to run the display and will be posting the code and datasheet when it is done.
msPROBOT Ready for Maker Faire
I finished the first physical version of the msPROBOT just in time for Maker Faire. I have the majority of the demo code written and I will post it when I test the code. All the basic library functions are written. Just need to make a main program that strings it all together.
There is more information and PCB files you can download at the msPROBOT project page.
Printf Function for microcontrollers.
So this is meant to be paired with a UART program. This code is not all my own but I could not remember where I found it. I have edited the original quite a bit but the same structure is still there. If someone recognizes it please let me know so I can give credit.

MSP-430 LaunchPad UART and FIFO
I just put the finishing touches on my extensive UART and FIFO library. It uses the MSP430G2553 chip which has a hardware USCI. This can be used for a hardware UART. There are a couple different options to choose from and versions with or without a FIFO.
I will be making a standalone FIFO library so one can be used to store data.
edit: The standalone FIFO library is there now. Not fully tested but should work.
Self Balance Robot Lives!
I have been slowly working on the robot for awhile now. It runs on the MSP-EXP430 board which has a built in accelerometer. The Code is almost done. Should be finished tomorrow. When im done I will be posting the build sheet and code so other people can make it. Unlike other self balance robot designs that cost upwards of $200, this one costs just under $80 to make it and you do not need any special tools to make.
MSP430 32 LED Driver PCB Done
Finished the VU. Changed the name to a 32 LED Driver as that is what it really is. The idea for the VU is to sample the sense line via an ADC a couple times and average the value. Then the MSP430 will look up that value on a table and light up that many LEDs. Should be fairly straight forward.
