HI Everybody
First let me say this is a great forum, I learned a lot and progressing slowly with my reef pi build. I do have a problem and I hope somebody might be able to help me. To make things easy I purchased the dosing pump adapter and reef pi hat that Mr Lane designed. I am trying to create an all in one setup. For this reason I am running the pump adapter through the hat so it can all be controlled from one pi. I have a seperate 12v power supply going to the doser adapter, and I am taking ground from the hat's doser pin out. For the signal I am using pins 4,5,6,7 from the goby hat. I installed the pca9685 driver, and went through the setup as described I defined the pins at the connector section, and set the time and frequency at the doser pump section.
But I can not get it to work. I am probably missing something really simple since it is very straight forward.
Any help is greatly appriciated
thank you
