For the RS485, you just need config-pin p9.11 uart config-pin p9.13 uart ...and then use /dev/ttyS4 For the CAN, you just need config-pin p9.24 can config-pin p9.26 can ...and then you can use something like https://gist.github.com/jadonk/90d3462c8569d11fa3f7caf14f4769f1, but replace can0 with can1 For the 4-20mA loop, the ADC overlay should already be loaded and you can cat /sys/bus/iio/devices/iio\:device0/in_voltage5_raw cat /sys/bus/iio/devices/iio\:device0/in_voltage6_raw ...but you'll need to do the voltage to data conversion For the sink drivers, you can do: # Sink A config-pin p9.15 gpio echo out > /sys/class/gpio/gpio48/direction echo 1 > /sys/class/gpio/gpio48/value # Sink B config-pin p9.23 gpio echo out > /sys/class/gpio/gpio49/direction echo 1 > /sys/class/gpio/gpio49/value ...and that should turn them on.
