TMS320F280025C: Data transfer from RS485 serial port to PC using SCI function

Bob

Part Number: TMS320F280025C
Other Parts Discussed in Thread: C2000WARE

Hi，

Ti friends,

The current requirement of the customer is to use the chip function of the F280025C to transfer the sampled data to the PC via RS485 and watch the transferred data values in real time, and would like to modify the relevant routines to simply implement this function.Which routines are easier to implement by modifying them?

Thanks!

Hello,

Could you clarify what you mean by routines? Are you referring to driverlib functions? There is an SCI example in the C2000Ware training folder that demonstrates transmitting to a PC port. Does the customer wish to use this example as a starting point but simplify it for some reason?

Thank you,

Luke

Yeah，It's just a matter of roughly modifying which of the officially given routines like driverlib functions will achieve the relevant functionality?

Thanks!

There is no need to modify the SCI example in the C2000Ware training folder to achieve this functionality. The example demonstrates communicating between a launchpad/control card and the COM port in CCS.

An explanation and walkthrough of the example can be found here:
