Re: Hot tub / spa / jacuzzi controller

Ok, well let’s see what I can find out. Any pointers on how you did this would be great. I’m not the best when it comes to signals but I learn fast. Maybe an example of your code based on your findings and how you got the times etc.

Thanks again.

Re: Hot tub / spa / jacuzzi controller

It has been awhile since i looked at the functions available in the .NET classes, but in C# IOT, there is event for detecting rising and falling edge, i have tested these a few moments ago with a simple circuit and push button. Here is my code. So i can definitely tell when an GPIO (Input) is going ...

Re: Hot tub / spa / jacuzzi controller

Thanks JeanL. I ordered a cheap signal analyzer from amazon. So has anyone got some code samples of what they are doing once they understand the clock signal rate and signal pattern? It’s been a long time since I done this, but was hoping to see come code. It’s raining now, so I won’t be messing wit...

Re: Hot tub / spa / jacuzzi controller

Thanks Guys, I have a good understanding of writing and reading the GPIO,s. My main problem is that i don't have anything to read the signals, so i was thinking trial and error based on what i found on this forum. I agree with all the comments, I will be sure to figure out the signals (voltages) for...

Re: Hot tub / spa / jacuzzi controller

I am wondering if i can tackle the same project. I am curious how Jayfun got on doing this project? Have we any examples on how to read signals using the PI. I have an RJ45 connection, so i will try drive them high with the PI and a resistor when i get a chance, but the main goal will be to have my ...
