Sharing my enthusiasm too!

this little app shows my solar panel output for the last hour , samples at 60 sec interval

grey lines are at 16 14 12 volts [can't figure how to add text labels to graphics yet




prescaled sample input from pic

each sample is a two digit decimal scaled to suit the graph ( sample * 10) - 140 + 50

graph y range = 100 points , mid point of display is 14 volts so y range is 9 to 19 v with 0.1 v resolution

if sample = 15.8 volts then graph_sample = 158 - 140 + 50 = 68

graphic refreshes every 15 sec and the pic feeds in fresh data every new sample (60 sec)
