I just use some radioshack piezo... i get a beep from it, although there are better things you can do... lastaid's code generates a more sophisticated tone for example... sergiocampama, your code doesn't compile in IAR, something about the interrupt vector Seems like there is compatibility problem between IAR and Uniarch... Error[Pe070]: incomplete type is not allowed C:\Users\brian\Documents\MSP\main.cpp 110 Error[Pe020]: identifier "interrupt" is undefined C:\Users\brian\Documents\MSP\main.cpp 110 Error[Pe065]: expected a ";" C:\Users\brian\Documents\MSP\main.cpp 110 Warning[Pe012]: parsing restarts here after previous syntax error C:\Users\brian\Documents\MSP\main.cpp 132 Error[Pe169]: expected a declaration C:\Users\brian\Documents\MSP\main.cpp 133 Warning[Pe012]: parsing restarts here after previous syntax error C:\Users\brian\Documents\MSP\main.cpp 135 Error while running C/C++ compiler Total number of errors: 8 Total number of warnings: 4

hmmm.Did miss it.. I kind of heard only two beeps, or may be I'm missing the point. Yeah, it's not a very interesting video. The point is to stash it near a co-worker or something along those lines and over time these beeps will start compounding in their minds and annoying them. Ideally you will want to have a speaker at an annoying frequency.

I hear some of the cheapest private islands in north america are in Nova Scotia...

How do you use EasyMSP in IAR? I tried adding to to project but got build errors.

I don't know this for sure, but I think you will want an external multiplexing chip. Maxim makes a few. You could also use shift registers i think.
