# I2C FRAM driver
|
||||
|
||||
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
|
||||
i2c_fram.writeByte(addr, 42)
|
||||
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())
|
||||
buf.setNumber(NumberFormat.Int32LE, 4, input.acceleration(Dimension.X))
|
||||
i2c_fram.writeBuffer(addr, buf)
|
||||
basic.pause(1000)
|
||||
}
|
||||
```

# 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);
|
||||
}
