Hi,
What is the sampling frequency of the A/D.
What is the maximum samples per second I can read from the ADC by SW (using C++) ?
Thanks.

Re: ADC sampling frequency
The maximum ADC frequency is 15K samples/sec in 10 bit resolution mode.
ADC can be connected to 128 bytes FIFO. SW can read fifo with sub_fifo_read.
Can you tell me what is your application and what ADC sample rate and number of channels required?

Re: ADC sampling frequency
I would like to sample a single channel at 10KHz. How do I setup the ADC for use with the FIFO? I don't see a definition for ADC in the fifo_config(). Thanks,

Re: ADC sampling frequency
This feature is not implemented yet.
Can you tell us a bit more about your project? Sampling at 10KHz with 128 bytes FIFO may be a bit problematic.

Re: ADC sampling frequency
I want to measure the measure the voltage drop across a current-sense resistor on the power supply line for a processor as I vary the frequency and CPU calculations to see the effect on power consumption.

Re: ADC sampling frequency
I see.
Well, what measurement precision do you need in mV ?
Is it something on-time or will it go to a number of products/items ?
This is not a simple feature to implement and I want to know all details.

Re: ADC sampling frequency
This is a one-time school project. I was just trying to leverage my existing sub20 rather than buying another DAQ system. I don't expect you to implement this - I just thought from the earlier posts on this thread that the functionality was already in the firmware, hence the question.
