Sorry for my late reply Sean, but glad my post helped you out. I’ve built de PI + Mixxx setup for a theater and I honestly do not know if they still use it.

Pi3b+, good quality outboard DAC box and I’m looking for no frills/low processing draw and just relaiable straight up playing of 2 audio sources with cueing and basic dvs features.

I tried on Mixxx forum to ask this question (going backwards for something basic) but got not joy so pleased to find some info to give me a steer. Looking forward to trying it and wondered if you still use the pi3 with that version of Mixxx still?

Are there any hazards for not putting in more resistors or will it just be safe to keep doing it like this?

I do not know the sensor or board so without a schematic drawing or picture, I cannot help you out.

I’m using a SKR Mini e3 board with a proximity sensor (EZABL clone). If I sense voltage across the connector going to the board, it’s only 2.5V open and then 1.9V close (sensing something). I assume I need to get the closed state closer to 0/GND so it will trigger. Is that correct? Also not sure how to fix that in firmware but have tried – can I hard wire a resistor myself in line with the connector or similar? Many thanks.

Hey Bruno,

You seem to forgot to connect your RAMPS sensor input pin to the protoboard pin.

Right now you are connected like this: “protoboard pin -> diode -> sensor” which causes the protoboard pin to be pulled low when the sensor is triggered. As the diode prevents any current to flow from the sensor wire to the protoboard pin, there is nothing else right now that can ever cause the protoboard pin to go up to 5V.

You should ALSO connect your RAMPS sensor input pin to the protoboard pin. If the RAMPS sensor input pin, is pulled high (either by a resistor or configuration) THAT is what can give you a high measurement when the sensor is not triggered. The end result is: “protoboard pin -> diode -> sensor” AND “protoboard pin -> RAMPS sensor input”. The “RAMPS sensor input” should pull it UP to 5V, the “diode -> sensor” should pull it low to GND.

Kind regards,

Wesley

Doesn’t the sensor come with any documentation at all?
