Operation
Use rotary encoder as an input method for GEM. Optionally, connect SH1106 based (or compatible) display with I2C interface. Set switches SW1 and SW2 according to pinout of the display module (if compatible). Select voltage, required by the display, by shorting J1 header with jumper cap (for either 5V or 3.3V supply). Connect display module (directly or via jumper wires) to J2 headers.
Toggle switches SW1 and SW2 only when board is powered off to avoid potential short circuit caused by inner contacts bounce!
Examples
Encoder/SH1106 shield can be used to replicate the following test benches:
- AltSerialGraphicLCD (as an encoder input device)
- U8g2 (as both encoder input device and display connection)
- Adafruit GFX (as both encoder input device and display connection)
