Other Parts Discussed in Thread: SYSCONFIG,

Dear, sir,

I want to set McBSP as SPI Master in SYSCONFIG and send and receive 32bit data at 10Mhz clock.

I would like to know how to set it up on SYSCONFIG and which sending/receiving functions should be used.

[Development environment]

1. DSP : TMS320F28377D

2. CCS : V12.4

3. C200WARE : V4.3.0.00

4. SYSCONFIG : V1.17.0

[SPI setting]

1. McBSP(A) -> SPI Master

2. SPI CLOCK : 10MHz

3. Send and Receive Data : 32Bit

-> Repeated sending and receiving within the main while(1) statement.

The attached should configure the mcBSP as you have requested. The only assumption is that the F2837x is running at 200MHz and the LSP clock is 100MHz(which I believe is the default). If that is different you will need to adjust the SRG Data Clock Divider.

Best,
