Hi folks :)

I am new here and have 3 IOPi Plus boards in use. Sofar i have not come across an issue i could not resolve myself.

This post is therefor not a question, but to make the community aware of 'iopipin', a small program i wrote that may be usefull to other users of these boards and this forum seems like the place where those users come ;) I placed iopipin under  a GPL licence as i beleive in open source. Open source has been kind to me and i like to pay it forward as well.

iopipin is designed to be a back-end utility program for direct pin operations (set to input either with or without pullup, set to output, write to and read from pins) and exits with different exit codes depending on the compiled in defines and arguments from the command line. It has the ability to 'reserve' pins. These pins are blocked from operating on. In my use case, there are 2 pins on one board in use by the OS to handle its own power supply

It can be used from the command line, in shell scripts and in other programming languages that can execute shell commands.

If there is any interest and it is ok to post external links to software here, i will do so in a later post in this thread

kind regards,

Fenna

Hi Fenna

You are welcome to post a link to your software.  I am always interested in seeing how our expansion boards are being used and I am sure other people will find your software useful.
