PI4-CASE-ARGON-ONE

Argon One Service and Control Service coding by golang for Raspberry Pi 4B/4B+ centos7.7 or other Pi Linux System

Enjoy it.

1、Hardware

• Raspberry Pi 4 Model B Rev 1.2
• PI4-CASE-ARGON-ONE

2、Rom & OS

• CentOS 7.7 Download Rom and Flash to SD

3、Boot config file(very important,if not do this, application can not run normal.)

open i2c dev driver

### vim /boot/config.txt and add next info
dtparam=i2c_arm=on,i2c_arm_baudrate=32000
dtparam=i2s=on
dtparam=i2c_baudrate=32000

### vim /etc/modules-load.d/modules.conf and add next info
i2c-dev
i2c-bcm2835
i2c-bcm2708

4、Reboot && check config work or not

• (1) check i2c dirver work

[root@pinas2 modprobe.d]# lsmod | grep i2c
i2c_bcm2708            16384  0 
i2c_bcm2835            16384  0 
i2c_dev                20480  0 

• (2) check i2c baudrate(32000 is OK)

[root@pinas2 tools]# cat /sys/module/i2c_bcm2708/parameters/baudrate
32000

• (3) check ARGON-ONE device('1a' is device address for fan)

[root@pinas2 tools]# yum install i2c-tools -y
[root@pinas2 tools]# i2cdetect -y 1 
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- 1a -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- --  

• (4) check cpu temp

[root@pinas2 tools]# cat /sys/class/thermal/thermal_zone0/temp
44790

5、How to build

//ssh to your board and prepare Pioneer600
//and install git tools 
sudo apt-get update
sudo apt-get upgrade
sudo apt install -y vim git build-essential i2c-tools
sudo apt install -y golang

//clone code 
git clone git@github.com:panyingyun/argonone.git

//build 
cd argonone/cmd

//build arm
CGO_ENABLED=0 GOOS=linux GOARCH=arm go build  -o argonone

6、How to run

argonone -c prod.yml

7、Auto-run when reboot OS

Run build_arm64.sh, it will autorun argonone when reboot os

chmod 755 build_arm64.sh 
sudo sh build_arm64.sh 

Other shell cmd

// enable 
sudo systemctl enable argonone.service

// disable 
sudo systemctl disable argonone.service

// start service 
sudo systemctl start  argonone.service

// stop 
sudo systemctl stop argonone.service

// restart 
sudo systemctl restart argonone.service

8、Check Result

When CPU Temp from 41.381℃ to 39.92℃ ,and fan speed from 10% to stop.
