hi all I have 7 photocell connected to 101 to 107 input ( connected to 10k resistor ) , with supplying voltage 3.3v , I always saw the voltage spikes in the reading ... what is the recommendation on the frequency to read the ADC input ? the 32 usb Numato was access by node-red serial port modules and pump the data to mqtt broker .
I am also interested in this specification. What is the response time for the A/D conversion? I also need the spec for the 8-channel version. Is there no one to answer?
Sorry for the very very late reply, The recommended conversion rate is one conversion every 20 - 50ms or so. It can be faster but the rate should be adjusted to suit the needs of the application. We recommend averaging a few samples to smooth out the glitches that can be caused by different environmental factors. Thanks, Tom Numato Lab
