CFF3000 GPIO Interface
Unfortunately, the + and - terminal of the green LED are both labeled as - in the photo of the CFF3000.
Just as an idea it may be possible to design the pcb in a way it would be able to be directly applied to the gpio pins of the rapsberry pi 3b plus? and maybee there is a way to somehow „include“ the remote onto the pcb and remove the battery from it?
Is VCC and GND on J3 (GPIO domain) the same as on J4 (CFF domain)?
I would assume no, right (should come from, e.g., raspi).
Then, what voltage level is it designed for?
Also, is there a possibility to drive the whole CFF via the Pi's VCC (possibly with a step-down converter)?
Hi, I try to follow your instructions, may I ask where CFF3000 the green + should be? The photo shows green - twice.
Thanks in advance :)
