Maybe you're using the wrong MSP430?
On that note, have you done any comparisons of the pic16f1824 to the MSP430 4xx or 5xx/6xx series? I don't know exactly what your requirements are, but these two series of MSP430 appear to have chips with similar features/price to the PIC chip you named. Just thought I'd mention it. I think it would be kind of interesting if SDCC supported MSP430's. Not really a suggestion, just more of a thought. ------------------------------------------------------------------------------ The modern datacenter depends on network connectivity to access resources and provide services.
