CCS/CC3220SF-LAUNCHXL: ADC FIFO and DMA header files and examples.

Thank you very much for your quick response. I do appreciate it. Unfortunately this did not resolve the issue. The API described in the _a_d_c8h.html and the _a_d_c__c32_x_x_8h documents do not contain the bindings to functions such as "unsigned char ADCFIFOLvlGet (unsigned long ulBase, unsigned long ulChannel)" , unsigned long ADCFIFORead (unsigned long ulBase, unsigned long ulChannel), and void ADCDMAEnable (unsigned long ulBase, unsigned long ulChannel) which are referenced in section 13 of the swru456.pdf document.

The closest that I can find are functions from the CC3200 driverlib library. An implemetation is available at github.com/.../adc.h, ...adc.c. These functions *do* match the documentation in the swru456 doucment.

This begs the question, is the implementation from the cc3200 processor compatable with the cc3220sf processor. Is the code for these functions burnt into the ROM of the cc3220sf processor, and is the API for driverlib exposed?

The big picture: I would like to get time-stamped ADC data from multiple channels dma transferred into the processor. The documentation suggests that this can be done. Unfortunately the examples and documentation that I have seen in the SDK use a single shot polling mode. This includes the two versions of adc.c, and adc.h that you reference above.

I am working with the example located at
C:\ti\simplelink_cc32xx_sdk_1_60_00_04\examples\rtos\CC3220SF_LAUNCHXL\drivers\adcsinglechannel\freertos, and the documentation that you reference. Please note that in the examples, both threads do a "single shot" adc conversion. One thread does a single shot conversion, displays the results and exits, while the other thread loops through 10 single shot conversions on a different channel, displays the results and returns.


Thank you very much for your help.
