@stewartstarbuck will be pleased to know that RFID fun is getting closer… #badphotography
@cn Nice. It’s pretty fun seeing how the students at uni use them. Lots of interesting art projects.
@stewartstarbuck current status: lost your thread, and having fought apt-get for a significant time, not sure I have anything set up correctly
@cn I’m going to be writing up my coffee machine soon, go through the setup I used there. Anything specific that I can give you a hand with in the mean time?
@stewartstarbuck one round of searching gave me a setup with wire colours, cannot find it at the moment. The library you referred to would be useful.
I got two wires right because the LED lit; I believe the pi3 has SPi capabilities …
@stewartstarbuck this isn’t my first run with GPIO or SPI afaik*; just somewhat more convoluted
- one humidity/temperature sensor; a Pi Zero with an SPI network board
@cn github.com/ondryaso/... is the library I used. Includes pin wiring in the readme. What I keep getting caught out by is the BCM vs physical pin numbering. I suggest sticking to one for all your pi stuff!
@stewartstarbuck I bought a second board. I tried wiring the first two different ways, and only succeeded in lighting its LED; I am probably imagining that an added print() statement showed an instance of one of the libraries, at least one of which needed pin number modifications
@stewartstarbuck the NFC capability of Android ’phone (plus apps) reads all the cards I’ve tried. I look forward to the pin assignment chart for the coffee machine; pin 1 3.3v orange etc.
@cn Hm I’ll try and get something up this week about how I have mine wired. That LED on the module is usless, all it tells you is the reader has power, no use for debugging!
@stewartstarbuck the 18th Dec twitter post seems to show 3.3v being a GPIO pin, so you switch the module on yourself?
As for debugging, I could possibly parallel the GPIO on the pi–topCEED, since I got this project its own Proto board
