TMS320F28379S: PTO library doubt

Hi,

Just two doubts about PTO library.

1) Can PTO support floating point output? An example: 10 pulses input, 3 pulses output.

2) Can PTO support absolute encdoer input and then PTO output?

Thanks a lot.

Jordan,

I am consulting on a colleague and will get back to you with an answer shortly. In the meantime, if you haven't done so already, checkout this application report on the PTO library http://www.ti.com/lit/an/sprac77/sprac77.pdf

Ozino,

Thanks for your reply.

The doc for PTO library, I already saw it. Inside, Floating is not supported.

And this is why, I need to double to check with you.

On the other hand, I'd like to know, if it's possible to support floating, with x.xxx, that's 3 decimal places.

Thanks a lot.

Jordan,

Your understanding is correct. Floating point is not supported.
Note that if you need to support this, computation need to happen in CPU/CLA.
Once the CLB tools are available (end of 3Q19) - you/customer can develop their own algorithm in s/w for computation and use CLB for pulse generation.
