[IAEP] [OLE Bolivia] [Sur] TI MSP430 running on XO 1 - Robotics!

[Yama Ploskonka]

Yes, I have continued doing some with MSP430s with very limited time.
No, I have not done much documenting, alas.
My biggest accomplishment so far has been putting together a MSP430 and 
L293D - With that arrangement I can run either a pair of DC motors 
forward or aft independently, getting full control, or a bipolar step 
motor, with the only addition of a battery and a capacitor. The way I 
have it running now I actually have the MSP430 away from the Launchpad - 
I use the Launchpad merely as a programmer, otherwise the setup is just 
the 2 ICs and one capacitor - all coding using an XO 1.
see the tracked vehicle in
http://askjerry.info
Which I am using as part of activities with http://kidbot.org

Now that there is some need :-), I might get myself moving toward 
documenting.

BTW, you can sign up with TI.com to get free samples - simply use an 
.edu address - and they will send you for free extra MSP430 MCUs and L293Ds.
