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
* Update pio/ir_nec/README.adoc file links (#183)
The "List of Files" now links (only) to files, not to directories (which prevented this example being included in the C SDK databook)
Bug fixes and new examples

adc/microphone_adc - Read analog values from a microphone and plot the measured sound amplitude.
i2c/bmp280_i2c - Read and convert temperature and pressure data from a BMP280 sensor, attached to an I2C bus.
i2c/lis3dh_i2c - Read acceleration and temperature value from a LIS3DH sensor via I2C
i2c/mcp9808_i2c - Read temperature, set limits and raise alerts when limits are surpassed.
i2c/mma8451_i2c - Read acceleration from a MMA8451 accelerometer and set range and precision for the data.
i2c/mpl3115a2_i2c - Interface with an MPL3115A2 altimeter, exploring interrupts and advanced board features, via I2C.
i2c/oled_i2c - Convert and display a bitmap on a 128x32 SSD1306-driven OLED display
i2c/pa1010d_i2c - Read GPS location data, parse and display data via I2C.
i2c/pcf8523_i2c - Read time and date values from a real time clock. Set current time and alarms on it.
uart/lcd_uart - Display text and symbols on a 16x02 RGB LCD display via UART
* 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.
