Connecting the ALPHA Angle Encoder to the ZedBoard

When trying to connect an angle encoder to a ZedBoard it can become confusing because when searching the internet, you can really only find examples of an angle encoder connected to an Arduino. However, after some research and sessions of trial and error, we were able to determine a successful connection option.

When looking a the encoder, ALPHA should be listed at the top. The side that has three prongs is where we are going to be working. The three prongs at the bottom we will refer to as Prong 1-3, going from left to right. Prongs 1 and 3 are inputs and Prong 2 is ground.

An example of the specific connections we made when using the angle encoder are, Prong 1 connected to JA1, Prong 2 connected to ground and Prong 3 connected to JA2 (These specific connections JA1 and JA2 may vary depending on the code you are using). We were successful with these connections to the ZedBoard which can be further read about in Emily's Post titled, Angle Encoder.
