So thanks once again! I was able to get rolling values using the method described in list-serializer. However, it is refreshing the values in increments of 250 ms, whereas I should be seeing almost 1 million values every 40ms (as I can confirm in a graphic that my shell is generating). Ideally, this stream would pass in full resolution to an oscillator and flush immediately, so as not to clog the buffer. What am I missing?
