TMS320F28379D: I'd like to know about F28379D's PTO function.

Hello Sasaki-san,

This feature is already on our creative backlog for PTO.  Due to our current shop workload, it could not be scheduled for this year.but is targeted to be available in 2018. The concept that we have is that the existing libraries of Position Manager absolute encoder Master interfaces, EnDat, BiSS-C, T-format, (Nikon A-format coming) as well as the analog sensor solutions (SIN/COS and Resolver) would remain the same but would then also include a QEP output emulator (give it speed, direction and index/0deg) as an additional CLB logic function.  

The transformation of the absolute angle value to the QEP_EMU inputs (speed, direction and index) would need to be done by the customer using the CLA or the C28x (I think this is another great use for a CLA task).  In this way, a floating point scaling of the angle could be achieved during the transform as well.  My guess is that we would offer an example of a way to use the CLA/C28x code for one specific transformation but truly leave it to the customer to handle for their application.

We are open to other ideas/thoughts from the community on this concept.  Please feel free to add to this thread with your ideas/wishes for a QEP Output Emulator function on future CLB-enabled C2000 MCUs.
