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.

Excellent project and thanks for sharing the code and discussions. I learned new a lot from the discussions and suggestions.

[mudnducs]

Thanks

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

Hello Thehomeengineer,
Awesome build, i would like to build one for myself too, could you share wiring schematic?

[tonyfoale]

Hi Garage Nut
I have posted the code on HMT (above).......... I am more than happy for members on HMT to rip the code apart and tell me how I could improve or made it better. I feel the programming is as messy as the wiring in the control box but it does work.
The Home Engineer

I do not have the time to go through your code in detail, but my initial impression was that the Mega code was very long for the tasks. I might think differently if I waded through it all.

You last function "software_Reset()" is defined but a search did not find any instances of it being called.

The posted Nano code looks to be missing a chunk. As posted it does nothing.
You attach an interrupt "attachInterrupt(0, runEncoder1, RISING );" but there is no "runEncoder1()".

Home Engineer - did you use an arduino mega for the memory requirements? or some other reason?

[thehomeengineer]

Hi
If I remember I had to use the mega for the additional earth pins but I am no expert when it comes to arduino. this was my first project I have used an arduino and it was a steep learning curve. There is probably a lot better way of doing it but I eventually got it to work. ( took me a real long time ) luckily I got some help from a friend who was really good at coding so got some good advice.
