4 years ago Hi,
Why not add an external pullup resistor between OUT and VCC? That would be easier than reprogramming it.

Hi,
I am using the Escher 3D mini IR sensor board (V1.2) with a RUMBA board, which has a three pin Z- endstop connectors. It provides 5V on VCC, GND and has a signal input, which can be internally pulled up. Using the rumba with Marlin would easily work, but I am using the RUMBA with Klipper firmware, which runs on a separate host CPU (Raspberry Pi) and controls the RUMBA, which has a small version of firmware that executes the motion commands that the Klipper host sends it.
I am having issues with the mini sensor board starting in analog output mode (4 LED flashes) because Klipper sometimes takes a while to start (or restart, if you changed config) so the firmware in the RUMBA does not set the internal pull-ups on the Z- signal pin on time for the mini-sensor board to detect. I basically have to cycle the power or disconnect the mini board connectors every time, sometimes repeatedly, until the internal pull-ups are set by klipper. It is very annoying and inconsistent to get the mini-sensor board started in digital output mode.
I would like to simply hard code the mini sensor board so that it always starts in digital output mode. I am not a programmer and I don't have enough knowledge to modify/verify and upload the mini sensor board's firmware. Do you have a workaround or suggestion for how to hard code the sensor board to always start in digital mode?
I think this is something that should be implemented as a jumper (solder) on the board.
Thank you
