TMS320F28386D: FSI data Transmission test using CPU control

Part Number: TMS320F28386D
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hi team,

I'm studying follow the FSI with "Multiple Devices in an Applincation sync pwm".

Figure 5-8 in the document shows that transmission time takes approximately 16us when using two nodes and one leader.

But according to my measurements, it took about 50us.

What more can I check to shorten the transmission time?

Please advise.

Thank you for reading.

    Hi Hahmin,

    Are you running the example from here?  C:\ti\c2000\C2000Ware_\driverlib\f28xxxx\examples\fsi

    Also, to make sure you have 3 devices to run this right? and FSICLK is 50MHZ

    Can you please send the images of your setup?

    Thanks,

    Susmitha
