# I2C Read Number
|
|
|
|
Read one number from the specified 7-bit I2C address, in the specified
|
|
number format.
|
|
|
|
```sig
|
|
pins.i2cReadNumber(0, NumberFormat.Int8LE, false);
|
|
```
|
|
|
|
## Parameters
|
|
|
|
* ``address``: the 7-bit I2C address from which to read the number.
|
|
* ``format``: the number format. Formats include
|
|
**Int8LE**, **UInt8LE**, **Int16LE**, **UInt16LE**, **Int32LE**,
|
|
**Int8BE**, **UInt8BE**, **Int16BE**, **UInt16BE**, and
|
|
**Int32BE**.
|
|
* **Int** stands for "integer", and **UInt** stands for "unsigned integer".
|
|
* **LE** stands for "little-endian" and **BE** stands for "big-endian".
|
|
* The number in each format name stands for the number of bits in the format.
|
|
* ``repeated`` repeated start, true - don't send stop at end
|
|
|
|
## Example
|
|
|
|
The following example reads a number in big-endian, 16-bit, unsigned integer
|
|
format from the 7-bit I2C address `32`.
|
|
|
|
```blocks
|
|
pins.i2cReadNumber(32, NumberFormat.UInt16BE, false);
|
|
```
|
