I’ve cabled into the ADC2 port which has Gnd, Adc2, Relay1 to Relay4
Multimeter shows 3.3v across relay1 to relay4 regardless of what the Servo’s are set to on the Relay panel of mission planner. Im expecting 0v or 5v (low or high)
Actually, I think these pins are different, and not on main/aux busses at all. If I’m interpreting the hwdef.dat correctly, they are GPIO 1-4, meaning that you should set RELAY_PINx to a corresponding number, 1 through 4, to get them to work as intended.
Not that it matters as Ardupilot rules here but the Manual link on the Qiotek website isn’t working. Cloudflare bullshit. So perhaps they or the retailer that posts on the forum here can fix that.
And perhaps @Eosbandi would be so kind as to update the relay button labels in Mission Planner to just repeat the parameter name with which they are associated “RELAY_PIN”, “RELAY_PIN2”, etc, rather than the confusingly zero-indexed labels at present.
Thanks folks - thats amazing fast response and appreciated.
> Yuri - values 1-4 on RELAY_PIN1 to 4 Perfect ! - thanks.
I’ve had non-default values in there - so looks like it would have worked out of the box if i didnt copy my parameter set across a while back. These low values are undocumented - but i noticed the default values while posting at the top.
The documentation suggests they are +5V values. Im seeing 0v or 3.3v - all my relays to hand seem to be 5v logic. Thats an easier one
