(LSB) for 14 segment -> as for 16-segment, above for bar graph -> column 0 is the leftmost one, dot 1 (the one that lights up when you write a value of 1 or when you call zeroDisplay()) is the bottom one (wired to SEGG) for matrix -> pixel (0, 0) (the one that ...
RMS values ranging from 95 to 135 volts are indicated on a bar graph, and fast peak values ranging from 120 to 500 volts at the waveform crest are indicated by the selected LED cell flashing at a 1 Hz rate, with selectable peak hold time. An internal real time calendar/clock enables ...
