After spending time playing with my Raspberry Pi and having connected to my TV, I found it a pai to keep moving HDMI leads about. My TV only has 2 HDMI ports, 1 has the DVD/Sat connected to and the other has the PS3. I Normally connect the RPi to the HDMI port the PS3 is connectes to. But I don't always connect it back and then when my wife goes to use the PS3 she can't, and then get moaned at.
So I looked at HDMI Switches, these plug inline with the the HDMI lead to the TV and take 2 to 4 inputs. Selection of the inputs can be automatic or via a switch. What I find is a pain is having to go to the TV and use the switch to select the RPi. I use the RPi as both a media server and general LINUX usage. This got me thinking about connecting up a HDMI switch to the RPi and control the switch from the RPi. This is then the birth of PiSwitch.
PiS is a 3 to 1 HDMI switch controlled via 2 GPIO pins. It is based around a Texas Instruments TDMS361B. This blog will detail my journey in the development of the switch.
