Hi,

I would be grateful to anyone who could provide a short piece of sample code showing how to write and read SSP SPI in 16bit and 9 bit format.

To is to drive an SPI to MDB external chip.

Thanks!

Hello arm.nine,

Please refer to the STR750 standard library available on the net. You will find a basic example of how to use an associate SPI EEPROM driver to communicate with an M95640 EEPROM. I think the porting should be straitforward since the SSP IP is the same in the two products. I have just one comment, please take into account that the feature of managing the NSS pin by software is not available in STR91xFA.

Best regards,
