MSP430 LaunchPad arrived today

I ordered one of the $4.30 LaunchPad eval kits from TI a few weeks ago. It was immediately on backorder but to TI’s credit, when they had them, they shipped them quick — overnight FedEx from what I can tell. Nice.

I’ve only downloaded the tools – Code Composer Studio and IAR Embedded Workbench – which I’ve never used before. Should be interesting. I’ll check all this out once I work through my current (and ongoing) PIC32 composite video problems.


Exploring the PIC32 … and failing

I purchased Lucio Di Jasio’s book Programming 32-bit Microcontrollers in C (Exploring the PIC32) a while ago and love it. However, I’ve been struggling over the last few nights to get the composite video stuff to work on my PIC32 Starter Kit + IO Expansion board. The simple resistor DAC seems to be working fine but the output on the TV looks to have an extra pixel or two per line. A vertical line shifts right every line and then resets about every 8 lines or so.

I need to do more debugging with a scope attached to see what is up but it isn’t turning out to be turnkey — I suspect this is something to do with my setup and not the book or code itself.
