Tool/software:

Hi Champs,

Customer now want to use TMS320f28P65x to retrieve from ADS8588H, it will need 2 SPI on F28P65x to received data from ADC8588H(DOUTA and DOUTB).

Now customer want to quickly check is it possible to generate CLK and NSS with one SPI, two SPI receive data at the same time, and then read the value of the two SPI fifos with the receive fifo interrupt trigger of one of the SPI? And if it is possible do we have such a example?

Thanks!

    Julia,

    While we do not have an example for this, it sounds like the need is to read and write the data at the same time, while triggering the appropriate trigger which should be supported. We have C2000Ware examples that showcase using two SPIs with FIFO.

    Best Regards,
