Experiments with the Hormann HCP bus.
Yes... this is a code experiment only, do not consider it even close to usable for anything useful yet!
Inspired by https://blog.bouni.de/posts/2018/hoerrmann-uap1/
Tested and working just fine with LineaMatic P motor and the following platform combinations:
- Lenovo X220 laptop + USB FTDI RS232 + TTL to 485 converter module.
- Lenovo X220 laptop + USB 485 adapter.
- Raspberry Pi 3B plus + USB FTDI RS232 + TTL to 485 converter module.
- Raspberry Pi 3B plus + built in UART + TTL to 485 converter module.
Test experiment responds instantly to keyboard input using this code.
Should works with any Linux serial device. Make sure kernel modules are loaded and your serial device is showing up in /dev tree.
Install git, nodejs, npm & friends, then:
git clone https://github.com/raintonr/hormann-hcp.git
cd hormann-hcp
npm install
Assumes you have a USB/RS485 dongle connected and available as /dev/ttyUSB0. If not, edit the test code to update the path for your device. Ie /dev/ttyAMA0 for Raspberry Pi built in UART (noting this requires a TTL to 485 converter).
Start the program with npm start
You then get a couple of messages like this:
Setting up port...
Opening port...
To send commands you can press the number keys 1 up to 8 on your keyboard.
Uses node debug module with prefix hormann-hcp: so enable all debugging with:
DEBUG=hormann-hcp:* npm start
