Hi Cedric,
thank you very much for your precious information! I was really
expecting an answer not so great as yours, like "There are the boards
ECM-5718, xxx, yyy.", but your answers were much more complete.
I really appreciated your message. Again, thank you very much!
Best Regards,
Rodrigo.
P.S: I think a 600 Mhz would suffice for my application because I think
this processor can process a 480x240 color image for, basically,
threshold processing. Other required processing have few processing
power requirements. But for sensor data reading, I would need to have
maximum latencies of 20 us. But the data reading processing is very
simple and takes much less than 1 us. But anyway, it is not a commercial
application. It is just my robot with a sample program for validating
the framework developed in my Master thesis. I will not implement it
with SBC, but I want to be more specific when arguing that it would be
possible to use a SBC and show an example of SBC that could be used. But
I really like your message because I may need to develop real
applications in future and it is good to see your suggestions. Thank you.
