The next step is to get some sort of display onto the Android Things Raspberry Pi. I have a drawer full of LCD modules, based on the HD44780, that I have used before with the PCF8574 I2C IO port expander.
The Android Things preview image has java support for I2cDevice. Writing a driver for the PCF8574 was a matter of porting some code from my old AVR library.
Get Android Things running on the Raspberry Pi and run a hello world app from Android Studio.
Step 1 – Find a Raspberry Pi
Where are all my bloody Raspberry Pi’s? Oh yeah, One’s running Kodi, one’s a NAS, one’s … OK then, off to PBTech for a new Raspberry Pi. One quick trip into town the weekend before Christmas, no problem (Yay motorcycle ownership).
OK, USB for power. Can I use USB for adb too, nope on the Raspberry Pi it’s power only. OK, following instructions, “Connect to Ethernet.” Where’s that 30 meter Ethernet cable that reaches to the router.
