right then, the mechanicals of the probe have been built, as have the electronics and a calibration has been done i have discovered a problem the code allows the fuel value to exceed the maximum 255 for the output pin, and allows it to go below zero - this could happen in real life with variations in fuel, and temperature this causes the naon to go full scale on under empty, and zero on over full i intend to add these lines of code to hopefully stop this but if i add after the fuel calibration bit of code if (fuel > 255) fuel=255; if (fuel < 0) fuel=0; it compiles ok, just got to brave the cold garage with my laptop and a can of fuel and have anothe rgo |
