First of all I am new to the forum and searched all the topics regarding SWC, but feel like mine is a little bit different. Also I posted on XDA Developers, but couldn't get any help there yet. Reddit has only been somehow useful for now.
Back to the topic:
I am using an Chinese Android headunit (Joying) which has a Z-link app, that allows you to use CarPlay.
I bought a SWC (iDrive like) controller from the same company and hooked it up to the Key1 cable (only one was available on the SWC IR transmitter). The controls are limited to multimedia controls on the Android side, on CarPlay however only the Volume buttons work.
I discovered that the Z-Link app, allows you to assign keys in order to control CarPlay without touchscreen! As I suspected the SWC I bought didn't work, BUT the Panel keys did! I was able to assign the 'Back' button of the headunits panel keys, to 'Turn right' cursor of CarPlay for example.
Now, I was thinking what makes the touch panel keys work in CarPlay, and why the SWC keys do not. That's why I thought maybe the Arduino could be used, to find that out and make the SWC controller work in CarPlay.
Any idea how I can find that out, and how I can hook it up and make it work? I am a noob in electronics but I am able to soldier one thing or another and am ready to learn to program something in Arduino
Sorry for the long post, but I really want to make it work as it would improve drive safety and comfort!
Thanks in advance!
