    Hi metric taper
    I will have to look up what a ISR routine is but thank you for this info. Will research later
    many thanks again

    ISR= Interrupt Service Routine. Your code enables interrupts, (attachInterrupt(0, runEncoder1, RISING ); // encoder pin on interrupt 0 >>(pin 2 on arduino)), but I don't see a service routine. I see you have a CLI()=Clear Interrupt Flag, in the main loop of the program. But a ISR will be outside this main loop. Clearly the program is working, so the Arduino IDE put something to return, that is invisible to the end coder.
    Typically with quadrature encoders, the interrupt does the count up or down based on the A vs B phase outputs of the encoder. Maybe I'm missing something.

    I do like your design of having a dedicated processor as a feed back counter, with it's own display.

    That is some serious code to start with.

    Will take me a while to work through it and uunderstand it. My coding abilities are down to a couple of switches and LEDs.


    That's the truth!

    Hi All
    This means a great deal to me as I was unsure at times if I would ever get this project finished so thank you again for all the interest shown in this project. All I can say is "don't give up, just step back have a think and go again" (Frustrating at times)
    Totally made up with this weeks HMT of the week
