STM32F and Texas instruments DSP SPI communication.

[NSemrHomeInit]

Dear ST hello,

I am working on SPI communication between two boards, of two different companies.

TMS320F28397D of TI and STM32F429 of ST.

My question is about the SPI configuration in CubeMx, should I chose the Frame format TI?

2/When I chose The TI configuration CubeMx don't accept this frame? should I download any framework to let CubeMx accept this chose?

The issue is I am always receiving 255 side TI.

Thank you in advance,

S.Tarik,

> should I chose the Frame format TI?

"TI mode" means there's a pulse on NSS prior to the MSB of each byte. This is rarely what you want, even with TI chips.

Not sure what you mean here. Perhaps you can provide more information, or a screenshot. But TI mode probably isn't what you want.

Yes the same protocol with TI DSP,

Could tell me please why i have this red in clock configuration and peripheral please.

One thing please, Why I have this warning around the spi3?

 

Thank you for help
