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.
Example: Setting Argon ONE to Mode 2 (Always ON)
Type in the Terminal the code below:
i2cset -y 1 0x01a 0xfe
Write Command Only one byte(0~255) can be used
ACTION: Sets the Fan's Duty Cycle from 0%~100%.
NOTE: FAN only starts turning at 10% power input.
ACTION: Turns OFF the FAN.
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.
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.
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.
