CC3000 - SPI code example without DMA?

Other Parts Discussed in Thread: MSP430FR5739

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!

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
