CC3135: Communication related issues with chips

Part Number: CC3135

CC3135 supports UART and SPI, so how are these two communication methods chosen? How do I tell the chip whether I am currently choosing SPI or UART?

Hi Tony,

This is explained in the Network Processors guide.

Appendix D goes deep into detail.

This only discusses the communication specifications between UART and SPI, without specifying how to choose.

I would like to ask how CC3135 supports UART and SPI, and how are these two communication methods set up and selected? How do I tell the chip whether I am currently choosing SPI or UART? You didn't explain these issues clearly before.

Hi Tony,

The screenshot I posted above clearly states "Binding the communication interface to the host driver is done by defining the interface functions through the following defines in user.h"

In Laymans terms you will need to go to these function defines and instead of using the SPI driver use the UART driver to read or write from and to the host device.

Best,

Rogelio
