So the maximum Arduino ADC sampling rate is: 9.615kHz The above rate is the maximum sampling rate but to reproduce a sinewave requires double the sampling rate (Nyquist theorem). Another way of looking at it is that the bandwidth of the signal you can safely reproduce is half the sampling...

Hi, I have the circuit connected as shown above. Both CC2541 and Arduino are getting the SAME input analog voltage at the ADC input. They both have equal ADC reference voltage. However, when I look at the data in my laptop, I see that the CC2541 A...
