I am hoping to use an 8055 to sample a relatively low frequency analog signal, but I can’t see the spec for the ADC anywhere. Can anyone tell me the maximum possible sampling rate using this unit. I’m hoping to sample every 10 msecs or so, but I’m guessing that is pushing it a bit!
The USB communication polling interval is about 10ms. The analog data can be read every 10ms from the K8055 card.
Please see also this thread for some example code and a waveform captured: viewtopic.php?f=15&t=4171

That’s brilliant, thank you. I have built an amplifier for ECG signals and wanted to digitise the output. The main peak in that signal is about 40msecs wide, and a 10 msec sampling is able to cope with it.
