    Interface library for I2C protocol over FTDI-D2XX 
  </p>
</div>

## Installation
```
  npm install --save i2c-ftdi-d2xx
```

## Basic Usage
```
  const ftdi = require("i2c-ftdi-d2xx");

  const devices = await ftdi.list();
  await ftdi.open({serial_number: devices[0]});

  const SLAVE = ANY_NUMBER;
  const TARGET = ANY_NUMBER;
  const DATA = ANY_NUMBER;

  
  let res;
  res = await read({slave: SLAVE, target: TARGET});
  res = await write({slave: SLAVE, target: TARGET, data: DATA}); 

  ftdi.close()
```

## Burst usage
```
  const ftdi = require("i2c-ftdi-d2xx");

  const devices = await ftdi.list();
  await ftdi.open({serial_number: devices[0]});

  const SLAVE = ANY_NUMBER;
  const TARGET = ANY_NUMBER;
  const N = ANY_NUMBER;
  const DATA = [ANY_NUMBER, ANY_NUMBER];

  
  let res;
  res = await read({slave: SLAVE, target: TARGET, n:N});
  res = await write({slave: SLAVE, target: TARGET, data: DATA});


  ftdi.close()
```


## Field/Register Based Usage
```
  const ftdi = require("i2c-ftdi-d2xx");

  const devices = await ftdi.list();
  await ftdi.open({serial_number: devices[0]});

  await ftdi.setRegisterMap({registerMap: VALID_REGISTER_MAP})

  const SLAVE = ANY_NUMBER;
  const TARGET_REGISTER = VALID_REGISTER_NAME;
  const TARGET_FIELD = VALID_FIELD_NAME;
  const DATA = ANY_NUMBER;
  
  let res;
  res = await read({slave: SLAVE, target: TARGET_REGISTER});
  res = await write({slave: SLAVE, target: TARGET_REGISTER, data: DATA});
  res = await read({slave: SLAVE, target: TARGET_FIELD});
  res = await write({slave: SLAVE, target: TARGET_FIELD, data: DATA}); 


  ftdi.close()
```

## Advanced Usage
```
  const ftdi = require("i2c-ftdi-d2xx");

  const devices = await ftdi.list();
  await ftdi.open({serial_number: devices[0]});

  const SLAVE = ANY_NUMBER;
  const READ_TARGET = [ANY_NUMBER, VALID_REGISTER_NAME, VALID_FIELD_NAME];
  const WRITE_TARGET = {ANY_NUMBER: ANY_NUMBER, VALID_REGISTER_NAME: ANY_NUMBER, VALID_FIELD_NAME: ANY_NUMBER};

  await ftdi.setRegisterMap({registerMap: VALID_REGISTER_MAP})
  
  let res;
  res = await read({slave: SLAVE, target: READ_TARGET});
  res = await write({slave: SLAVE, target: WRITE_TARGET}); 

  ftdi.close()
```
