A few questions: Button controls (new PCB?), buying an assembled HAT, and touchscreen details

[Adisn922l]

Hi @JKBusse,

First of all, thank you for sharing this amazing project! I want to build this for my car, but I have a few questions regarding the hardware and your future plans:

1. Physical Buttons / CAN-BUS integration:
   I saw some discussions in other issues about controlling CarPlay using the original MFD buttons via CAN-BUS. Are you planning to release an updated version of the HAT (e.g., a v2 PCB) with an integrated CAN module to handle the button controls natively?

2. Pre-assembled Kits:
   Is there any possibility to buy a fully assembled and soldered HAT directly from you? I am interested in a ready-to-use board and, if possible, the necessary cables to connect it to the MFD.

3. Touchscreen Overlay:
   Could you clarify a bit more about the touchscreen integration? Do you have any specific parameters, keywords, or maybe a link to the exact 5-inch capacitive USB overlay you used? I want to make sure I buy one that fits perfectly inside the original frame.

Thanks again for your hard work on this!

Hey!
Great to hear, that people are interested in this.

Physical Buttons / CAN-BUS integration:

Well, planned is a little bit exaggerated. Theoretically it should not be so hard to emulate a TV Receiver to get the Button input from the MFD, but I haven't made any progress in this. The problem is, I have a Touchscreen retrofitted on my MFD, so my incentive in this is quite low 😅

Pre-assembled Kits:
Is there any possibility to buy a fully assembled and soldered HAT directly from you? I am interested in a ready-to-use board and, if possible, the necessary cables to connect it to the MFD.

I am out of PCBs at the moment, but I can order more. I have more Cables than I need, so no problem there. If you are interested, send me a email: jkb@freieslabor.org

The only one that I could find that's fits is this one: https://www.ebay.de/itm/173606913219

Thanks again for your hard work on this!

No problem!

Are you still interested? I will soon order some more PCBs.
