Winterhill with Node Red
Re: Winterhill with Node Red
It looks like J4:4 (RX Valid) on the Ryde header, through R25, 330R.

Re: Winterhill with Node Red
Thanks Mike!
BTW, I'm using a DS1820 temp sensor on the 1-Wire connection and reading its data via Node Red which is installed on the WH Pi4.
The bonus of using Node Red on the WH Pi4, is that its so much quicker than when I was using a Pi3!
Just leaving this information here in case someone else is looking for the same information.
I'm using the temp sensor on the heatsink of my amplifier.
Thanks

Re: Winterhill with Node Red
What I don't know doesn't worry me. I am not measuring PA temperature or current. Better for the nerves. It would be nice to measure the forward and reflected power values though. Is there an ADC that works in the same way?

Re: Winterhill with Node Red
A quick search reveals the DS2438Z (Smart Battery Monitor), which as a 1-5V ADC with a 1-Wire output. Whether it will work with a Pi will need to be researched I guess. Then I presume just some python script to read the value.
Why not just use a ADS1115?
I also want to measure forward and reflected power. I believe I have forward power nailed with the little board I recently made. I am thinking of buying another coupler and install it in reverse. I believe this gets me any reflected power. Then I just need to figure out how to calculate the REF.
Cheers
