Part Number: TMS320F28375D

Hi Champs,

According to this TRM page 2127 on "Configuring a GPIO to emulate SPISTE",

C2000 SPI seems not support "multiple SPI Slave" connection like a cathcade.

However, GPIO is possilbe to emulate SPI slave. is it correct ? we want to connect three slave SPI from C2000 (master).

If this connection is pooible as above set up, Do you have any sample code for multiple slave as same as GPI emulate method ?

Regards,

Hi Kz777,

We do not currently have any sample code for multiple slaves. Any of our SPI examples could be easily migrated to this. You will just need to toggle a GPIO low for the appropriate slave before transmission, and return it high upon completion.

Kris
