About the DeskPi Pro

The DeskPi Pro is a hardware kit for converting a standard Raspberry Pi 4 from a naked SBC, with limited storage, into a mini PC complete with a power button, cooling, better ports and, via SATA then USB3, 2.5" or M.2 SSD storage.

Please Read this section carefully

• if you are using 64bit OS, The script to control the fan is in the installation/drivers/c/ directory. The file suffix with 64 means 64bit, and the 32bit executable file has been removed, if you want to use 32bit, please download the repository and compile it by yourself.

• Before you install this script, please make sure your Raspberry Pi can access internet and can access github website.

How to install it.

• 1. Download the Repository
• 2. Enter installation directory
• 3. Select Your OS type
• 4. Execute shell script inside the OS folder.

For example:

For Raspbian OS 64bit (bookworm)

git clone https://github.com/DeskPi-Team/deskpi.git 
cd ~/deskpi/installation/RaspberryPiOS/64bit/
sudo ./install-raspios-64bit.sh 

For Volumio OS Version: 2021-04-24-Pi

• Image Download URL: https://updates.volumio.org/pi/volumio/2.882/volumio-2.882-2021-04-24-pi.img.zip
• Getting Start:　https://volumio.github.io/docs/User_Manual/Quick_Start_Guide.html
• Make sure your Volumio can access internet.
• There are some steps need to do.

sudo nano /etc/network/interface

make sure following parameters in file /etc/network/interface

auto wlan0 
allow-hotplug wlan0 
iface wlan0 inet dhcp
wpa-ssid "YOUR WIFI SSID"
wpa-psk "YOUR WIFI PASSWORD"

and enable the internet access by typing this command in terminal:

volumio internet on

and then reboot your DeskPi.

sudo reboot

###Setting Fan Speed Manually

• Open a terminal and typing:

deskpi-config

Select 4 and press Enter, you would see the fan is spinning and the front USB port are now available.

NOTE: Once you execute this deskpi-config command, the deskpi.service will be stopped at background.

you will need to execute sudo systemctl restart deskpi.service to re-activate it.

If deskpi.service is in a stopped state, it will not read the configuration in the /etc/deskpi.conf file to control the fan.

Therefore, if you want the fan to operate automatically according to your custom temperature settings, please ensure that the deskpi.service is always running in the background, especially after executing the deskpi-config command, you need to manually restart the deskpi.service by executing sudo systemctl restart deskpi.service command in a terminal.

How to control fan speed mannualy.

• Open a terminal and typing following command:

deskpi-config

You can follow the instructions to setup fan speed level by typing numbers as following example:

Selection explain

• The number from 1 to 4 is to setting your fan speed to a static level.
• Number 5 is just turn off the fan.
• Number 6 is to guide you to create a file located to /etc/deskpi.conf and you can specify the threshold of temperature and fan speed level according to your idea, once the file has been created, the program will according to the configuration file to setup your fan.
• Number 7 is to enable automatic fan control by default paramaters. ** Default arguments:

TEMP   : Fan_SPEED_LEVEL
<40C   : 0%  
40~50C : 25%  
50~65C : 50%  
65~75C : 75%  
>75C   : 100%  

** If you want to change it, just typing :

deskpi-config

Select 6 and then input 45 and enter, and then input 50 means setup the fan speed level to 50% when CPU temp is above 45 degree it has 4 level to setup.

NOTE: 50% Speed level means you have already send PWM50 to /dev/ttyUSB0 port, and this port will available when you add dtoverlay=dwc2,dr_mode=host to /boot/firmware/config.txt file and reboot your DeskPi.

How to boot from USB SSD/HDD?

After initial Raspberry Pi Configuration and once you have Internet Connectivity established, Install the DeskPi Pro Utilities from https://github.com/DeskPi-Team/deskpi.git Open a Terminal / Console and run the following commands:

sudo apt update
sudo apt full-upgrade
sudo rpi-update

When complete, run:

sudo reboot

Upon reboot, open Terminal again:

sudo raspi-config

• go to Advanced Options
• Select Boot Order, select #1 USB Boot, Return to Advanced Options,
• Select Boot Loader Version, choose Latest Version
• Save & exit

Reboot again (to restart with new settings)

sudo reboot 

After reboot, re-open Terminal again

sudo -E rpi-eeprom-config --edit

• do not change anything, it is unnecessary • press Ctrl-X to save, answer Y to overwrite file.

sudo reboot    

Now you are ready to install Raspberry-OS onto your USB Boot Device. You can use the Raspberry Imager from www.raspberrypi.org website. Depending on device the new SD Card Copier can transfer the SD-Card image to the USB Device (ensure you select generate a new UUID). Once your USB drive is imaged & ready to boot, shutdown your Deskpi-Pro, remove the SD-Card and power-up to boot from the USB Boot drive, once running & configured you can install your additional software and proceed as usual.

How to Use IR function onboard.

1. You need to enable gpio-ir function by modify /boot/config.txt file. uncomment this line if not exsit please add it.

dtoverlay=gpio-ir,gpio_pin=17 

2. Install lirc package:

sudo apt-get install lirc

3. Modify configuration file on location: /etc/lirc/lirc_options.conf and make sure it has following parameters:

driver          = default
device          = /dev/lirc0

4. Reboot your Raspberry Pi and test it with following command:

mode2 -d /dev/lirc1
