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.

Advantages and Features

Firmware

• 🛠️ Forget about RDM protocol handling: No need to deal with frame parsing, timings, or UART interrupts

• ❌ No libraries needed: Just use standard I2C functions
