Razberry HA Module & WiringPi gpio
Posted: 19 Nov 2014 03:04
Hello all,
Has anyone tried calling WiringPi from inside a HA module?
I seem to be having some troubles. Empirically it's as if my calling of the gpio command just "doesn't happen."
Example:
Returned this:
I haven't been understanding for sure, but I'm guessing the "0," that is returned is some kind of wrapping by the system() call. Point being, nothing is actually being returned.
When it should be returning something like this (This is me running it manually):
I have similar results when I try reading individual pins or (most importantly) setting a pin's on/off state. The command is accepted (I have whitelisted gpio in the .syscommand file) but it just doesn't return anything. And when it is supposed to execute the commands to set pins on/off I will manually read the pin's state (after the set command "completes) but the state is unchanged.
There are no errors being reported in the /var/log/z-way-server.log nor in the system log.
Has anyone else experienced this?
Edit:
For what it's worth I am able to successfully execute other commands through system().
For example this command executes just fine even though it is piped through multiple commands. So I'm at a loss why gpio is being the exception.
