    Add more bandwidth, faster signals use pin_Watch for digital signals

    Simmulation Based on ESP32
    Only draw plots that have a signal connected
    Auto scale signal to 1.5, 2, 2.5 or 3 cycles
    Use timer start more effectively?
    more accurate duty, Hz calulations on non triggered channels
    narrower scan line, shaded dark green?
