TMS320F28P550SJ: BISSC implementeation on f28p5550

David Capdevila

Part Number: TMS320F28P550SJ

Hello,

We have been reading the application note regarding bissc implementation on devices like f28p255 wqith CLB. I would like to confirm the hardware requirements as we are passing from a 64 pin mcu to 56 pin mcu with only 2 CLBs, therfore, for that application, which are the pins, and peripheral reservations in total.

2 pins in total? One corresponding to epwm and the other one corresponding to SPIMOSI?
EPWM4 or it can be anyone
1 SPI?

Is there any place where we can obtain the original source code?

Regards,

David

Apologies for the delay - I was out of office for a few days.

I've attached a draft port to the P550. The directories can be dropped into the MC SDK https://www.ti.com/tool/C2000WARE-MOTORCONTROL-SDK

directory structure - libraries/ and the solutions/

The software license is the same as the MC SDK license for the P65x. All of the source code for the P65x is also in the MC SDK.

I included a diagram of the input/output that should answer your questions. You can also refer to table 2-3 in the design guide (https://www.ti.com/lit/ug/tidue73/tidue73.pdf) The PWM pin is not a requirement - it was used as a way to export the CLB output on older devices. The P65 and P55 have more ways out of the CLB to a pin so it is much easier to find a path.

Regards,

Lori
