INSTASPIN-BLDC: Integrating SCI communication in Instaspin

Part Number: INSTASPIN-BLDC
Other Parts Discussed in Thread: TMS320F28069M

Tool/software:

Hello 

I want to use SCI communication on TMS320f28069M controller on GPIO 9 and GPIO11 when instaspin FOC is running. 

Individually Instaspin and SCI is working but together it isn't.

Any references??

    Hello,

    If you're having issues only running both at the same time, check your hardware- are GPIO9 and 11 the correct IO pins for the SCI? Are they also being used for something related to motor control? If that does not solve things, consider how much time is an SCI ISR taking, if you're using one. Is it interfering with the motor control process?
