as1107 outputting font browser with rotary encoder interrupt based code
Raw
gistfile1.c
/*
Playing around for midi_touch_v2. part 1 (redo 20)
* AS1107 on SPI0 connected to 8x8 matrix
* Rotary Encoder on ;
- PD0
- PD1 (both sides of the rotary)
- PD2 to one of the switch pins
- rest of the rotary pins to ground
This is a energia sketch ment for a stellaris
Niceness about this;
- interrupt based decoding of the rotaryencoder
- hmm dno, font works?
