TMS320F2800137: About SCI Interrupt and PWM Pulse Output

yong luo

Using SCI interrupt reception, the baud rate is 9600, and the PWM output is abnormal, as shown in the following figure. How can I solve this problem?

best regards!

Hi Luo,

Could you please elaborate on what the exact issue is and the context? Is it that you are seeing a different SCI baud rate than what is programmed? Or are you using SCI to send information used to generate an EPWM output waveform and seeing an incorrect EPWM?

What is the desired signal output and what is the incorrect signal output? It is unclear from the images you posted.

Best Regards,

Allison
