LAUNCHXL-CC2650: SSI - SPI / READ/WRITE

Emocs

Hello,

I see the technical manual of CC26x0 [CC13x0, CC26x0 SimpleLink™ Wireless MCU] ( swcu117g.pdf ) and I would like to understand the Chapter 20 about the Synchronous Serial Interface (SSI). I would like to use and build a SPI interface based on the SSI base.

Is there any example for the read/write and implementation of a FIFO through SSI ?

It would be very helpful in order to understand how I can define and implement it in practice.

I am looking forward to hearing from you as soon as possible.

Kind regards,

Hi,

You can check SPICC26XXDMA.c or even lower level ssi.c/.h (from driverlib,
C:\ti\tirtos_cc13xx_cc26xx_2_21_00_06\products\cc26xxware_2_24_03_17272\driverlib)

Hello,

Thank you for your message but possibly I am not clear.
For exactly this (SSI.c and .h) I talk about, is there any example by TI which uses this in order to read/write such as the FIFO which is mentioned to the technical manual? If there is an example like this, could you please let me know which is this?

Thank you,

Then you can find the function usage in ssi.c/.h in SPICC26XXDMA.c file.

function name : SPICC26XXDMA_flushFifos
