GPIO and ADC both are not working - Cube Orange

ArduPilot Lua Scripting

I’ve 5V and 3.3 volts from a LiDAR if there is any obstacle. I’ve used these two cases to change the mode of the rover to stop.
I’m not sure where I’m doing wrong.
My Ardu version: 4.5.7

Case 1 using AUX / GPIO pin

I firstly change SERVOx_FUNCTION parameter is to “-1”.

gpio:pinMode(53,0) -- set AUX 2 to input, gpio:pinMode(51,1) would be output

local function aux1_is_high()
gcs:send_text(3, "getting high")
return gpio:read(53) == 1
end

function update()
    local mode = vehicle:get_mode()
    
    -- Check AUX1 GPIO voltage
    local aux1   = aux1_is_high()    
    -- If AUX1 has voltage (3.3V detected), switch to MANUAL mode
    if aux1 and (mode == 10 or mode == 15) then
        gcs:send_text(3, "Obstacle voltage detected! Switching to MANUAL.")
        vehicle:set_mode(0) -- MANUAL mode
    end
    return update, 1000 -- Check every 1 second
end

Case II - ADC

Pin Signal Volt
1 (red) VCC +5V
2 (blk) ADC IN
3 (blk) GND GND

What could be best case. Please check the wiring in the attached picture.
Is there anything, I’m missing, Please help

The GPIO read binding returns a Boolean value, not an integer.

Also, there is no entry point for your script. You never call the update function after defining it.

Thanks Yuri, I’ll try this and let you know
