The MCC example app for their Bluetooth ADC you asked about is here:
The example shows sampling 2 channels at 500hz without buffering, with good following of ‘higher’ frequency signals.
Your latest app/firmware seems a little more responsive than before, but still not quite enough for what we need.
Would the solution to greater responsiveness be simply adding the option for a 1-sample ‘buffer’ (plus some lower sample rate options to avoid sampling more data than is necessary at that low-ish end) ?
BTW how do I now turn off the current graph when I only want to see voltage ? Could the graph also retain its user settings, rather than reverting to defaults each time you go back to the main screen to tweak something ?
