5. Setting Up the Pironman¶

Configuring Shutdown to Deactivate GPIO Power¶

To prevent the OLED screen and RGB fans, powered by the Raspberry Pi GPIO, from remaining active post-shutdown, it’s essential to configure the Raspberry Pi for GPIO power deactivation.

Manually edit the EEPROM configuration file with this command:
```
sudo rpi-eeprom-config -e
```
Modify the POWER_OFF_ON_HALT setting in the file to 1. For instance:
```
BOOT_UART=1
POWER_OFF_ON_HALT=1
BOOT_ORDER=0xf416
```

Downloading and Installing the Software¶

Note

For lite systems, initially install tools like git, python3, pip3, setuptools, etc.

sudo apt-get update
sudo apt-get install git -y
sudo apt-get install python3 python3-pip python3-setuptools -y

Proceed to download and install the source code from GitHub.

cd ~
git clone https://github.com/sunfounder/pironman5.git
cd ~/pironman5
sudo python3 install.py

A system reboot is required to activate the installation. Follow the on-screen reboot prompt.

Here are the primary configurations for Pironman 5:

The OLED screen displays CPU, RAM, Disk Usage, CPU Temperature, and the Raspberry Pi’s IP Address.

If you run Raspberry Pi Desktop, you can press the power button twice in quick succession to shutdown. If you run Raspberry Pi OS Lite without a desktop, press the power button a single time to initiate a shutdown.

To force a hard shutdown, press and hold the power button.

Four WS2812 RGB LEDs will light up in blue with a breathing mode.

Modifying the Configuration¶

The pironman5 module offers basic configurations for Pironman, which you can review with the following command.

sudo pironman5 -c

The standard configurations appear as follows:

config file:/opt/pironman5/config.txt

temp_unit = C
rgb_enable = True
rgb_num = 4
rgb_style = breath
rgb_color = 0a1aff
rgb_blink_speed = 50
rgb_freq = 1000
rgb_pin = 10

Customize these configurations to fit your needs.

Use sudo pironman5, sudo pironman5 -h, or sudo pironman5 --help for instructions.

config file:/opt/pironman5/config.txt

Usage:
pironman5 <OPTION> <input>

Options:
start                start pironman5 service
stop                 stop pironman5 service
restart              restart pironman5 service
-h,--help            help, show this help
-c,--check           show all configurations
-a,--auto            [ on ],enable auto-start at boot
                    [ off ], disable auto-start at boot
-u,--unit            [ C/F ], set the unit of temperature,
                    C or F (Celsius/Fahrenheit)
-re|--rgb_enable     [on/true/off/false], whether enable rgb strip,
-rn|--rgb_num        the number of rgb lamp beads, default 4
-rs,--rgb_style      rgb strip display style, default: breath,
                    in [breath / leap / flow / colorful / colorful_leap]
-rc,--rgb_color      [(HEX)color], set the color of rgb strip,
                    default: 0a1aff
-rb,--rgb_speed      [speed], rgb blink speed (0 ~ 100, default 50)
-fq,--rgb_freq       [frequency], rgb signal frequency (400 ~ 1600, default 1000 kHz)
-rp,--rgb_pin        [pin], rgb signal pin, could be [10 / spi/ SPI / 12 / pwm/ PWM] or
                    [21 / pcm / PCM], default 10
-F,--foreground      run in foreground

Note

The -rp command is currently unavailable, please disregard it for now.

Verify the pironman5 program status using the systemctl tool.
```
sudo systemctl status pironman5.service
```
Alternatively, inspect the program-generated log files.
```
cat /opt/pironman5/log
```
To deactivate automatic program execution at boot:
```
sudo pironman5 -a off
```
To reset the RGB LEDs’ color:
```
sudo pironman5 -rc ff8a40
```
You can directly modify configurations in /opt/pironman5/config.txt.
```
sudo nano /opt/pironman5/config.txt
```
Press Ctrl+X -> Y -> Enter to save and exit.
