-This library provides a driver for this FRAM part: https://www.adafruit.com/products/1895

-The memory is accessed one byte at a time. The library provides a utility functions
-to write an entire buffer.

-## Reading/writing byte
-
-```
-let addr = 100

-let val = i2c_fram.readByte(addr)
-console.log(`${addr}: ${val}`)
-```
-
-## Reading/writing a buffer
-
-This code will log current time and acceleration in X axis every second.
-
-```
-let bufSz = 8
-for (let addr = 0; addr < 0x8000; addr += bufSz) {
-    let buf = pins.createBuffer(bufSz)
-    buf.setNumber(NumberFormat.Int32LE, 0, input.runningTime())

-    i2c_fram.writeBuffer(addr, buf)

-# NeoPixel driver
-
-This library provides a driver for various Neo Pixel LED strips, 
-see https://www.adafruit.com/category/168
-
-NeoPixels consist of a number of RGB LEDs, every one of them controlled
-separately.  
-
-## Basic usage
-
-```blocks
-// Create a NeoPixel driver - specify the number of LEDs:
-let strip = neopixel.create(DigitalPin.P0, 24)
-
-// set pixel colors
-strip.setPixelColor(0, 255, 255, 255) // white
-strip.setPixelColor(1, 255, 0, 0)     // red
-strip.setPixelColor(2, 0, 255, 0)     // green
-strip.setPixelColor(3, 0, 0, 255)     // blue
-
-// send the data to the strip
-strip.show()
-```
-
-Use `strip.setBrigthness()` to lower the brightness (it's maxed out by default).
-
-Use `strip.shift()` or `strip.rotate()` to shift the lights around.
-
-## Example: Using accelerometer to control colors
-
-This little program will let the position of the microbit control the color of the first LED.
-This first LED will then get shifted further away every 100ms.
-
-```blocks
-let strip = neopixel.create(DigitalPin.P0, 24)
-while (true) {
-    let x = input.acceleration(Dimension.X) / 2
-    let y = input.acceleration(Dimension.Y) / 2
-    let z = input.acceleration(Dimension.Z) / 2
-    strip.setPixelColor(0, x, y, -z);
-    strip.shift(1);
-    strip.show();
-    basic.pause(100);
-}
