TMS320F28P650DK: Different C2000 devices achieve carrier synchronization through MCAN.

Hello,

The MCAN_FEVT signal is a Filter Event that can be triggered when a CAN message with a filterID that matches the configured acceptence filter value is recieved in an RX Buffer. I am currently not aware of any examples we have for implementing PWM carrier synchronization via CAN, but I am looping in a fellow expert to provide any additional insight.

Hi,

The Table 22-3. ePWM SYNC Selection in TRM lists all the source which can be used for epwm counter sync in.

MCAN is not a valid source event for PWM carrier synchronization.

Thanks

Hello, in the manual, MCAN_FEVT can be connected to PWMXBAR, then connected to the sync of DC, and finally connected to the sync of TB.
So I would like to know how MCAN_FEVT is generated~

Thanks for the clarification on the request and that you want to know how MCAN_FEVT is generated.

Will transfer back to MCAN expert

Hello,

As mentioned in the original reply. The MCAN_FEVT signal is a Filter Event that can trigger when a CAN message with a filterID that matches the configured acceptence filter value is recieved in an RX Buffer.

The SFID2[8:6] bit fields are used to control whether or not the FEVT[2:0] events are generated on a filter match.
