I’ve got C-Bus lights at home and I wanted to tie them into openHAB so I decided to (surprise surprise) use a Raspberry Pi to bridge the gap. I already had a USB to RS-232 cable, and the C-Bus setup had a Serial PCI Module, so I could dive straight into it. Here’s what I did to get C-Gate running.
Espruino is awesome and here’s a way to help fund it!
A bit unfortunate that I’ve got a stack of Wi-Fi HATs for the zero already, but I’m definitely happier to have this option. Should be good.
Cool product! I was actually looking for something like this a while ago, good to have a source now.
Just saw this on Hackaday, very nice technique for driving LEDs. I can’t believe we haven’t seen it before. It uses tricks with voltage drops to drive n²+2 LEDs with n pins, instead of the n²-2 that charlieplexing yields or the n of one-to-one connections.
