# Integration using I2C

Default I2C Address: **0x10**

## I2C Command Register Map

see [Pyr0-Piezo Parameters Explanation](../pyr0piezo-parameters/pyr0piezo-parameters.md) for more specific details on the command aliases.

## I2C Command Syntax

I2C input syntax uses "Least Significant Byte First" formatting, which means the data bytes are sent in reverse order:

```serial
[Address Byte] [Command Byte] [Data 8] ... [Data 0]
```

For example, to set the Logic output to Active Low:

```serial
0x10 0x06 0x00
```

Or to set VCOMP to 2650:

```serial
0x10 0x02 0x5A 0x0A
```
