## Description

# Description #

The **IS3710** is a chip that performs one job, does it extremely well, and is super easy to use (you don’t need any libraries — we love the KISS principle). It receives DMX frames and stores each DMX channel into its memory.

For more information download the **Datasheet**.

# How it Works? #

The chip has two ports:

- An **I2C interface **that connects to your microcontroller, FPGA, Arduino, Raspberry Pi, etc.
This is where you **retrieve the DMX data**.
- A **UART input** that connects to your favorite RS485 transceiver.
This is where the **DMX data arrives **from the RS485 transceiver.

The chip’s internal memory consists of **512 registers**, mapped like this:

    Register 1 → DMX Channel 1
    Register 2 → DMX Channel 2
    ...
    Register 512 → DMX Channel 512

Just read the channels you care about via I2C — and you’re good to go.
