LIRC IR blaster support

Here’s my second post :slight_smile:

So, while i was having troubles with bluetooth, I was also having trouble with the LIRC Library.
Since I’m trying to build the ultimate homebridge setup, I have been trying to find a method to control my projector remotely, which is when I found out about the LIRC library.
The only problem is that, for what I understand, the khadas boards do not support IR blasting by using the gpio as outputs (I’m using an arduino IR blaster module) out of the box. Raspberry pi’s do have this feature though.
Is it an hardware limitation? Or is there a way to compile/setup LIRC to blast IR codes by using the gpio outputs?

Please tell me there is a way, it would make me so happy :smiley:

no problem !! just clarify your problem

gpio as outputs ?
may be gpio as input ?
need send IR or receive IR ?

I would like for the gpio to work as outputs, so they can drive an infrared LED by using the lirc library.
Yes I need to send IR codes

u can get any unused gpio or unbind some used id dtb

test example

echo GPIO > /sys/class/gpio/export 
echo out > /sys/class/gpio/gpioGPIO/direction
echo 1 > /sys/class/gpio/gpioGPIO/value

next part is software which can work with this gpio
