Wixel ADC Sampling Rate


I’m planning on getting a couple of these for a project. I have a PIC in the current design that is just doing some ADC sampling. I realized I could maybe just do the ADC sampling on the Wixel.

What is the ADC sampling rate for the Wixel? I just need one channel and the 7-bit resolution is OK if necessary for max sampling rate.


Hello, Aditya.

The Wixel’s ADC conversion timing is documented in the section of the CC2511 datasheet, and also in the Wixel SDK’s documentation for the ADC library. If you choose 7-bit resolution, each conversion should only take 20 microseconds. You also have to account for the software overhead time because the CPU will take some time to process the result and restart the ADC.
