Setting up an RC15 board on a sprayer with 5 - 3 wire teejet valves(Constant 12v, Switched 12v and Ground) Used PCBSetup to upload the firmware with the default firmware, downloaded the latest rate control app, set it to ESP32, uploaded default values and have it set to 3 wire valves.
In the config page under relay control from what I’ve read I should have a PCA9685 single and paired option, neither of which is there, just PCA9685, which is what I have selected.
When try to toggle section 1 on it toggles 1 on and 2 off, then the opposite when I toggle off, section 2 toggles section 3 and section 3 toggles section 5… I tried switching to a 2 wire valve in the settings and then section 1 controlled section 2 and 2 controlled section 4.
Am I missing something in the settings or is there something else going on?
Update - I think part of my problem is the sprayer wiring that I was trying to tie into for those valves. Ran dedicated wires to one valve and then it worked! Except I hooked up section 5 to the section 5 pin and section 3 button was controlling it. Presumably because I have the 3 wire valve selected on the valve page, which has apparently replaced the single and paired PCA9685 settings. On the “paired” pinout it shows that pin as section 3a. I only need one wire sending 12v to these valves so I figured I would need the “single” pinout. When I select the two wire valve then it does absolutely nothing with any of the buttons.
SO my new question is, with these valves do I indeed have to use the “paired” pinout even though I only need to send 12v out on one wire to open and remove that voltage to close it?
Looks like the ESP32 remains in “paired” mode. Did you transfer selected “PCA9685 Single” to the ESP? If its a firmware problem @SK21 can help you out.
If using “paired” you can connect output (A) means 1A … 5A
Yes, I send and save every time I change anything. When I switch to the two wire valve, which is presumably single mode, I can’t control section 5 with any of the buttons
Ok I figured I could wire them accordingly since it seems to want to be in paired mode but I just wanted to know if there was something I was missing or if something else was wrong!
