Hello, I am trying SPI Communication, when I set clock frequency SpiaRegs.SPIBRR.all =0x007F; and clock frequency for SPI should be LSPCLK (50Mhz)/128=390KHz but I am reading from oscilloscope half of it, 195 Khz. Why does it happen? I am missing any other configuration?

Thanks,

Omer

Hi, please make sure you have predefined symbol "_LAUNCHXL_F28379D" in your CCS project. Look like it's not define hence you are getting 1/2 of expected frq.

Hello,

I went to Advanced Options and Predefined Symbols, than I predefined "_LAUNCHXL_F28379D" symbol, but it did not solve the problem.
