What
Our HDMI switches provide only a classic infrared remote control, to control them via the Slackomatic we will replace the infrared receiver with a few wav files and a small custom built amplifier.
How
The [LINK] cheap chinese HDMI switch we got has an IR remote control that comes with a 3.5mm audio connector to plug in a cape with a TSOP383.
This receiver was plugged into the audio port of a Laptop and the generated audio was captured.
That gave us 5 different Audio files.
The files were post-edited using ?? and now we can simply play them and aattch the audio out from the raspberry pi directly to the HDMI switch IR receiver port with a small piece of voltage converter logic inn between.
Data
Wav files with the recoded ir commands:
