I’m building a deskside clock radio because my ancient one is dying - I have several I2C devices running through a 3v/5v adafruit level convertor because the Adafruit display and Lux sensor run on 5V this means I cannot just plug the Speaker PHAT onto the Pi Zero with a 40way header…
The Lux sensor and Adafruit display respond to i2cdetect -y 1, the speakerphat doesn’t, I’ve tried speakerphat on its own and still no joy. I2C still works on the Pi so there’s no problem with anything other than speakerphat :-(.
Any ideas? - its not a disaster, I don’t want to use the VU meters but I’d like the i2c interface to respond [N.B. there’s no address clash]
P.S, Stretch, full GUI, on a Pi Zero… but that’s just for prototyping…
