# Argon-ONE-i2c-Codes

This is a list of i2c Codes utilized by Argon ONE Raspberry Pi Cases. 



**NOTE:** Operating system should have necessary libraries to control the Raspberry Pi GPIO.



# How to Send i2c Codes to the Argon ONE MCU



Example: **Setting Argon ONE to Mode 2 (Always ON)**



Type in the Terminal the code below:



i2cset -y 1 0x01a 0xfe



# Device Address：**0x1a**



Write Command

Only one byte(0~255) can be used



# 1.  HEX CODE: **0x01 to 0x64** (0~100)

**ACTION:** Sets the Fan's Duty Cycle from 0%~100%. 



**NOTE:** FAN only starts turning at 10% power input.



# 2. HEX CODE: 0x00

**ACTION:** Turns OFF the FAN.



# 3.  HEX CODE: 0xfd

Set the ARGON ONE to Mode 1：



**ACTION:** Sets "Default Mode"



**Behaviour:** You need to PRESS button to Power ON from shutdown or power outage.



# 4.  HEX CODE: 0xfe

Set the ARGON ONE to Mode 2：



**ACTION:** Sets "Always ON Mode"



**Behaviour:** Power current will flow directly to Raspberry Pi. NO need to PRESS button to power ON from shutdown or power outage.



# 5.  HEX CODE: 0xff

**ACTION:** Listens at Serial Port to cut power; Requires Serial Port to be ENABLED.



**Behaviour:** When ARGON ONE receives 0xff，then ARGON ONE will check UART's voltage.

Then, it will cut the power when UART's voltage is low.
