This is an Arduino library for driving the VL6180X range sensor module with the digispark-tiny board (attiny85 microChip) via I2C protocal.

The digispark-tiny dev board based on Attiny85 chip is low-cost, most mini-size board that I like to use. digispark-tiny board is also named as "Digispark USB Development Board - Digistump"

• Support for the Arduino IDE 1.0+ (OSX/Win/Linux)
• Power via USB or External Source - 5v or 7-35v (12v or less recommended, automatic selection)
• On-board 500ma 5V Regulator
• Built-in USB
• 6 I/O Pins (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB)
• 8k Flash Memory (about 6k after bootloader)
• I2C and SPI (vis USI)
• PWM on 3 pins (more possible with Software PWM)
• ADC on 4 pins
• Power LED and Test/Status LED

• attiny85 has no hardware Serial, so #include <SPI.h> will not work.
• #include <Wire.h> looks work here.
• directly use Serial.begin(); is not supported.

connect the VL6108X SDA with attiny85(Pin5_of_chip = Pin0 of board) connect the VL6108X SCL with attiny85(Pin7_of_chip = Pin2 of board) power on the VL6108X with 5V

vsCode + platformIO board: digispark-tiny refer to the file platformio.ini for more info.

put the folder "./lib/Tiny_VL6180X" and "./lib/Tiny_I2CDevice" into the /lib/ folder of your proj. #include "Tiny_VL6180X.h" in main.cpp compile, upload and run it.

The dep tree and developing steps is shown below:

```
Adafruit_VL6180X.h  <-- lib/Tiny_VL6180X/Tiny_VL6180X.h             (finished)
  -- Adafruit_I2CDevice.h  <-- lib/Tiny_I2CDevice/Tiny_I2CDevice.h  (finished)
       >ps: Is the Wire.h compatible with attiny85 here? 
    -- Wire.h <-- tinyWireM.h 
       >ps: Looks like the Wire.h is OK for attiny85. No need to write this.
```

refer to the "Adafruit_VL6180X" Arduino library, and modify the Adafruit into Tiny.

This repository is developed by modifying the "Adafruit_VL6180X" Arduino library. Thanks for their contribution!!
