please check the version by run `make `after install_BDsensor.sh instead of `./make_with_bd_sensor.sh` there will be a date in the version. ``` ~/Bed_Distance_sensor/klipper/install_BDsensor.sh cd ~/klipper/ make clean make ./flash-sdcard.sh .. ```...

seems there is a problem of data communication. `ValueError: invalid literal for int() with base 10: b'\x80'` do you have the schematic of that mainboard? you can try to increase...

you can try to use the pins in the EXP1 or EXP2

Could you try this ``` [BDsensor] sda_pin: PH3 scl_pin: PB5 delay: 25 ``` and is it the same error? `ValueError: invalid literal for int() with base 10: b'\x80\x00\xa8!'` > I've...

it works with the gpio pins from the raspberry pi https://github.com/markniu/Bed_Distance_sensor/issues/92 > can you use the gpio pins from the raspberry pi to connect the sensor?

about the warning for none 32bit mcu, should change this from: ` int addr=atoi((char *)args[2]);` to ` int addr=atoi(command_decode_ptr(args[2]));` also have updated to github

how about disconnect the BDsensor and send M102 S-1? to see if it still crashes.

I have tested and it works on the atmega2560 board at early with marlin firmware. here this problem should be the data protocol error from the mcu to the pi....
