Hello:
I got the TI CC3000 kit and got the sensor application / orbiting planet demo to work. Now I am trying to hook the LS Research TiWi-SL module to one of my boards.
I’m having trouble figuring out what parts of the generic driver I need to change to make it work on my hardware.
It seems to me all I would need to do is modify the SPI and I/O pin code. However, all of the examples I can find are for the TI part that uses DMA.
My micro has basic SPI send commands. Are there any non DMA examples I can look at for reference?
Any feedback or input is welcomed and appreciated!
Thanks again!
Paul
Hi Paul,
The only examples for SPI using DMA are demo application with Stellaris LM4F232-W.
The sensor application for MSP430FR5739 from the kit does not use the DMA for SPI.
You can find all the example application in the following wiki page:

For more information regarding the porting procedure please refer to:

Hi Paul,
Please don't forget to change the driver logic as well. The driver assume that once it's dong "write" all the packets are send, and it's changes the Chip-Select (CS). So an additional change of CS AFTER the DMA is complete needs to take place
