Hello everyone. I know this question is not 100% related to the MSPGCC, but I also know that MSPGCC mailing list comprises of many experienced embedded programmers that might have an answer or advice.
Currently I'm writing a SPI management module. At my disposal I have two different operating systems - Oleg Skydan's SOS and famous uC/OS II. At any time the CPU is a master device and there is about 5 different peripherals sitting on that bus. Now, some of those are just simple external memory chips that are not time sensitive. On the other hand a touch screen controller, CPLD, require certain response time, if not met the "event" will be lost. I want to write, once and for all, a platform independent, robust SPI management module. I think that mutual exclusion can be achieved by simply using the semaphores available through the OS. As well as the priority. Sorry for not being very specific, I'm just starting this thing so I was hoping to get some pointers and insight from the people that might have done something similar. SPI has been around for a long time, and I'm sure people had figured out efficient schemes and ways to implement this hence by starting from scratch I feel I would be "inventing the wheel". Thanks a lot, m.
