Analog to Digital Signal Converter

Hello dear community.

Okay, here's the translation:

"For example, I now have the necessary IDs. I want a device that can capture these IDs and output them as an analog signal, such as 12V. And conversely (it doesn't necessarily have to be all in one device), for example, if I press a button, a specific ID should be transmitted."
At work, we get these boxes custom-made for vehicle models at a high price. They are used for data loggers. For example, signals like the horn, turn signals, and low beam headlights are read from the CAN bus and converted into analog voltage levels that are then sent to the data logger.
I want to install a proven alarm system, which is a bit older, and I need a translator device similar to the ones we order at work. However, I also need a device that can send ID signals, for example, to lock a door.

What kind of hardware do I need to use for this? Are there any ready-made solutions available online? Or do I have to build something myself?


Thank you for your patience. And I apologize for my German.

Arduino Uno with a CAN bus shield. This should be the simplest and most cost-effective solution.

Is this Arduino with a CAN shield a component? Can it perform both functions? Is it programmed using a laptop and software?

And a huge thank you for the quick response.

Arduino is a microcontroller board that can be relatively easily expanded with various components and modules.

The software is available as freeware, and you can program it using a laptop.

The programming language is actually quite simple; there are many examples to find online, and it's relatively inexpensive. I also enjoy experimenting with it...

Okay, so it's similar to a Raspberry Pi but smaller. So I would need to build a switching box that converts from 5V to 12V because this controller operates at 5V. Thank you, that's a good idea.
I understand that you can handle this. Could you please recommend a website or book where I can learn more?

The Arduino website provides everything you need to get started, including a learning section, a forum, support resources, a blog, and even the hardware itself that you can purchase there.

Otherwise, the principle is... learning by doing .

Hi Pawel,

Since I've also installed similar devices quite often, I can only recommend the Ampire CAC200. It's a ready-to-use and tested solution for significantly less than the Signalboxes designed for UDS systems.

Greetings, club members!

PS: Soon, no external signal box will be needed for the UDS-AT anymore.

It might also be possible to solve this with a CAN-Power-Gateway. While it's another "off-the-shelf" solution, it ensures that you don't risk damaging the CAN bus.
The CAN messages used to activate the outputs can be freely configured.
I'm planning to use this to control a garage door opener via the multifunction steering wheel.

Garry.
