I have a HDMI switcher which uses a TL1338 IR LED that's connected via a 3.5mm audio jack. It has its own remote for switching between the inputs, but I want to use my TV remote.
In order to do that I want to connect the IR led to an ATTiny85 to receive the input and send the 'translated'code to the switcher.
When analysed with an oscilloscope it seemed that Arduino Libraries output a PWM signal, while the TL1838 outputs a digital signal. Is there a way to simulate a TL1838 signal?
