I’ve been working getting this to talk to the Raspi. It’s a great partner to the Pi since it runs at 3.3V and you don’t have to worry about precise timing. Not exactly plug-and-play though (at least not for me).
I ported the example arduino code with partial success. Feel free to start with my code. I wasn’t able to get hardware SPI to work, so I am bit-banging the SPI bus. That makes it easy to set up, but unfortunately it uses almost all of the GPIO pins!
Right now I am able to send commands and that works great, but I can’t get status messages or any inbound communications. It was working perfectly earlier in the day and then magically stopped. Not sure if there’s an error in the code or in hardware, but I don’t have the equipment to figure that out on my own. Fortunately, I don’t really need that functionality for my project, but if someone figures out what I’m doing wrong, I’d love to know.
No public wish lists :(
