-This project is to convert the PI-Plates Relay Plate Python Code to CodeSys.
+Background

-Steps for Project
+I purchased this Relay PI-Plate and it works very well using python. I though i could expand its uses with codesys and make my own driver. I emailed the support and asked for a C library or if they would explain more about how the driver works. They said no, they would not help. The python libaray was the only thing they would supply, but I was welcome to develop my own library based on their python library. I read how to develop a SPI bus device driver on the forge and though I would give it a shot. Below is what I discovered so far.

-1.)  Discover how the relay plate works using python.  Code can be found here:  
+My main goal would be to add a device under the SPI bus master and map each relay to a boolean value. Also the relay. I would like to get also poll all the board information and map that to a variable.

+GPIO Used, I will write out what they are for when I find out.
+
+The following pins are dedicated to Pi-Plates and cannot be shared:
+Pin 22 / GPIO 25
+Pin 26 / GPIO 7
+Pin 16 / GPIO 23
+Pin 15 / GPIO 22
+The following pins are used for SPI communication and can be used by other SPI-enabled devices selected by CE0. They cannot be used for GPIO:
+
+    Pin 19 / GPIO 10
+    Pin 21 / GPIO 9
+
+    Pin 23 / GPIO 11
+    The following pin may be used by Pi-Plates if their features are enabled:
+
+    Pin 12 / GPIO 18
+
+    The following pins are reserved for future expansion:
+
+    Pin 16 / GPIO 23
+    Pin 18 / GPIO 24
