You will need a relatively fast processor to handle that. 200MHz would be probably the minimum with a uC, I guess 400MHz with a linux based system. > Since I don't want to fill in the list with off-topic posts, just limit > in time-related quests. > There's not any problem for the board I'll use, I referenced the > raspberry because it's well known. Yes, but in embedded there are huge differences between the various boards and processors. While an rpi is a great device if you want to do graphics based stuff, it's a very poor choice for control and measurment applications, or anything that needs fast I/O > My questions are for the software > side and relative efficiency of the system. The software side varies with the CPU and the subsystem used. I don't know what linux offers as facility to use the timer units. A quick glance at the code didnt reveal anything. Worst case you would have to write a small driver (probably 100-200 lines of code) for it. If you want, I can ask some of my friends to see what is available for this kind of stuff.
