82eae4c8ea Added a 14 segment LED example, driven by the HT16K33 (#219) 
No fritzing parts available for the device so no diagrams

aa9a72b494 Refactor the oled_i2c example (#217) 
This PR does a number of things:

1. Renames the oled_i2c example to sssd1306_i2c to match other example folder
   names that use the device name
2. Merge code from another ssd1306 exmaple that was sitting in another PR
3. Add a few more demo parts to the code for extra fun.
4. Couple of bug fixes that were reported in original code to fix handling different
   display sizes, so code now works for 32 and 64 pixel height displays by changing
   a define at top of code.

72e41ad66f Fix PIO count (#211) 
Works fine currently for low frequency, breaks down at higher frequency e.g. 1MHz

Chased down with a scope to the 3 extra cycles needed for wait+1; mov; jmp
so account for these in demo program

* Use PIO IRQ accessors in PIO I2C example

74aff26c75 This should make using the WS2812 examples a bit easier. (#84) 
* This should make using the WS2812 examples a bit easier.
Moved parameters to the top as defines:
- Number of LEDs in your NeoPixel/WS2812 strip/ring
- Flag if the LEDs are WRGB or not
Changed PIN to 2 as pin 0 is used for serial UART.
