The DIO is manipulated through tsctl, or through manipulation of the registers directly.
Using tsctl will be the easiest way to communicate with the IO. This example will show the simplest way to toggle the IO, but see the tsctl page for more advanced usage.
# The easiest approach is to invoke tsctl directly.
# Do not do this if the tsctl server is already running.
# Toggle the DIO high and low directly as follows:
tsctl DIO SetAsync 8160_DIO_1 high
tsctl DIO SetAsync 8160_DIO_1 low
# If you want to share the tsctl functionality
# among multiple processes or access it via TCP/IP,
# you will need to run the tsctl server and access it as a client:
tsctl --server
# Once the server is started it will daemonize and you can access it over TCP/IP.
# Toggle the DIO high and low via the tsctl client:
tsctl @127.0.0.1 DIO SetAsync 8160_DIO_1 high
tsctl @127.0.0.1 DIO SetAsync 8160_DIO_1 low
# Note that the '@' is optional if the host name is an IP address of form X.X.X.X
# For consistency we recommend always including the '@'
# Note in the above example, the values 8160_DIO_1, high and low are automatically
# looked up to produce integer values. You can also do this manually, as show below:
# Lookup the logical DIO mapping of the dio header pin 1
eval `tsctl 127.0.0.1 System MapLookup 8160_DIO_1`
# If you run this outside of the eval it will return:
# System_MapLookup_0=XXX
# where XXX is the actual logical DIO number.
# If you look up "high" it will return 1, while "low" will return 0
# note that lookups are case-insensitive
# Toggle the DIO high and low:
tsctl @127.0.0.1 DIO SetAsync $System_MapLookup_0 high
tsctl @127.0.0.1 DIO SetAsync $System_MapLookup_0 low
