Slave spi without CS

Good morning

I have a slave SPI working correctly. I would like to emulate the SSI functionality, just getting rid of the CS activation.

It should reset the communication if the clock for some reason stops during the serialization, being ready to begin from the

first bit at next incoming clock pulse.. Is there a suggestion??

Thank You

Hi,

As SPI slave, it could not using a GPIO pin instead of SPI slave SS pin function.

While, customer can consider to use four GPIO pins emulate SPI slave communication interface.

Wish it helps.

Have a great day,
Ma Hui
