how/where to connect hall filament width sensor from klipper

[seebaer1976]

Hi, got the octopus v1.1.

now I have recreated the hall filament width sensor(link to hall filament width sensor) and would like to connect it. unfortunately I can't find anything to which pins I have to/can connect it.

does anyone have an idea?

Kind regards mark

You need one/two of ADC-s : PA0-PA7 PB0-PB1 PC0-PC5 PF3-PF10 if not 1284 display - can try take a look on EXP2 - there is PB1+PA4 /Direct pins BTN_EN2 SD_CSEL/ or on WiFi -> SPI2_MISO SPI2_MOSI = PC2+PC3 /direct pins/ or may be thermal inputs T2/3/4 - if they not used - PF5/6/7 / here not sure about schematic ??? / PWR-Det - PC0 - / also schematic ? /
