spi master-slave for TMS570LS20x

Hello Dmitry,

I have forwarded your post to one of our software experts so that your questions and concerns can be addressed. They should reply to your post soon.

still no news ?

Hi Dmitry,

I do not have the 20x Board with me, but still I can write one example for you. 

You want Multi buffer mode(MIBSPI) or Compatibility mode(SPI) example?
I think I can do this, I will configure MIBSPI1 in multi buffer mode as Master and MIBSPI3 in Compatibiltiy mode(SPI) as Slave. Will it work for you? 

it would be great. thank you.

Dmitry,

Here is an example (already published on this forum) for a basic SPI Master to SPI Slave communication.

In this example, SPI2 (Slave) and SPI3(Master) are used. It is necessary to make physical connection  between SIMO, SOMI, CLK and CS(0) of both SPIs.

This code can easily be ported to your device.

SPI2 Transmit ans receive through Interrupt mode.
SPI3 Transmit and receive through Polling mode.

Please have a look and let me know if this is helpful.
