I’m using an old OpenSprinkler Beagle Board with a Rpi B v2, and it works ok. However, I installed on the same Rpi another app (EMON CMS) adapted for monitoring temperatures wireless. The problem is, OpenSprinkler is using GPIO14 and 15 for the rain sensor and relay (Old version) and I need the pins for serial Rx/Tx. There is no connection between the OpenSprinkler RS and RL pins and Rpi, but I suspect OpenSprinkler settings for those pins creates the error I have when trying to use /dev/ttyAMA0.
Where and how I should change OpenSprinkler files to avoid the use of GPIO 14 and 15 for OSPI?
