Hi,
I'm trying to get my pi to accept digital inputs, however, I don't have the ADC chip. I've managed to get the relay to work, however, I can seem to get an I/O menu item on the GUI. I also don't have /sys/bus/iio directory, however, I'm not sure if this is just for the analogue inputs. I've installed dbus-adc to see if that made a difference, but to no avail. Any thoughts or ideas?
I'm running v2.60-22
Cheers
Simon
Hi Simon,
You don't need the ADC chip to have digital inputs. The RPI's GPIO pins can essentially all be configured as digital inputs.
What does your config file gpio_list say?
Below an example:
# This is a list of gpio pins, set by the script /etc/rcS.d/S90gpio_pins.sh
# They are documented at: https://github.com/victronenergy/venus/wiki/bbb-gpio
# Format: <pin_number> <direction: in/out> <name>
#
# The <name> part is used to create an symlink in /dev/gpio.
# Relay 1 Pin 40 / GPIO 21
21 out relay_1
# Relay 2 Pin 38 / GPIO 20
20 out relay_2
# Relay 3 Pin 36 / GPIO 16
16 out relay_3
# Relay 4 Pin 32 / GPIO 12
12 out relay_4
# Digital input 1 Pin 29 / GPIO 05
5 in digital_input_1
# Digital input 2 Pin 31 / GPIO 06
6 in digital_input_2
# Digital input 3 Pin 33 / GPIO 13
13 in digital_input_3
# Digital input 4 Pin 35 / GPIO 19
19 in digital_input_4
# Digital input 5 Pin 37 / GPIO 26
26 in digital_input_5
