Function 'hal_pi_gpio.pin-NN-in' not working

Hello everyone,

I am trying to configure an RPi4 to receive an input signal from two optical sensors, acting as my all-home and all-limit sensors for my machine. I am using the hal_pi_gpio.c driver to configure my system to utilize the RPi4's gpio pins. The issue is I get an error upon starting my program: "Pin 'hal_pi_gpio.pin-08-in' does not exist". This error is repeated for all of my input pin commands, while my output pin commands work as intended. What am I missing here?

Below is the hal code in my custom.hal file:
loadrt hal_pi_gpio dir=0x231B007 exclude=0x1CE4FF8
addf hal_pi_gpio.read base-thread
addf hal_pi_gpio.write base-thread
net xstep               => hal_pi_gpio.pin-03-out
net xdir                  => hal_pi_gpio.pin-05-out
net xenable           => hal_pi_gpio.pin-07-out
net ystep               => hal_pi_gpio.pin-11-out
net ydir                  => hal_pi_gpio.pin-13-out
net all-home          <= hal_pi_gpio.pin-08-in
net all-limit             <= hal_pi_gpio.pin-10-in
net estop-ext         <= hal_pi_gpio.pin-15-in
net coolant-flood   => hal_pi_gpio.pin-12-out
net din-00              <= hal_pi_gpio.pin-16-in

Give this a shot

The man page seems to suggest the dir list is for the pins you want as outputs, The exclude list for pins you don’t want to use and those in neither list are inputs.

Thank you so much, I thought the dir mask was for both inputs and outputs.
