I used F149 to sample a two-channel signal at 2x40 kHz (internal ADC at 80 kHz aggregate sampling rate) and 8-tap FIR/decimate it to 2x20 ksmpl/s in real-time. The clock was 8 MHz and decimation code was optimized assembly. As far as I recall CPU was utilized at 80% (40 us processing time out of 50 us interrupt cycle). Device size probably does not matter much for sampling, but if you need to do any signal processing it is handy to have an HW multiplier. Sergei P.S. Tool chain and documentation/examples are really in great shape. I recently had a chance to use gnu tools with ARM7 and (surprisingly) it was much more work to get it going. The main difference is that with MSP430 you get everything from one place. The only weak spot IMHO is insight. Is there a binary for 6.x I can download?
Thanks for your infos. My experience with insight is that it is not very stable. Therefore I always use ddd. This works fine also under cygwin and the cygwin X11 server.
