Tool/software:
Hi there
This is a continuation of the following entry: System Interconnect - connection between MCSPI and TimerDue to my involvement in another project and an extended holiday, I was unfortunately unable to post a reply in time. I would like to take this opportunity to thank Swargam Anil and Nick Saulnier for their support.
In our project, we are currently still working on pin mapping for the SoC. Among other things, we need to find out whether the desired functionalities can be implemented directly with the Sitara / PRU or whether external electronics are still required.
To give you a rough idea of what we want to do, I have copied this block diagram (reference design).
However, in our system, we want to use not just one but two (different) absolute encoders. Can the PRUs be configured so that, for example, an EnDat and a BiSS encoder can be used simultaneously? These would have to be completely independent (clock rate, etc.).
Then it would also be possible to implement a proprietary interface based on an SPI interface on a PRU, which was actually the subject of my original question. I don't think I fully understand the whole PRU/ICSSG architecture yet, so it's difficult for me to assess its potential and limitations. That's why I'm very interested in the PRU Academy.
Thank you!
Mathias
