​

CPUVInf - Raspberry Pi CPU Temperature & Voltage Reader by Nevil Verdoold
Version: 0.2 (Build 20)


Features:

• Fairly small script (2.75 KB)
• Temperature displayed in human readable °C (degree Celsius)
• Voltage displayed in human readable V (Volt)
• Current CPU temperature output
• Core voltage output
• SDRAM core voltage output
• SDRAM I/O voltage output
• SDRAM PHY voltage output
• Reading values through utils from raspberrypi-firmware-tools
• 100% support of all sensors on both Raspberry Pi models

Compatibility: Every Linux Distro with raspberrypi-firmware-tools installed!

Installation:

1. Connect your Raspberry Pi to power and let it boot up.

2. Login via SSH or a direct connection over a monitor with keyboard as root.

3. Installation:


wget http://kokakukidotai.cf/stuff/cpuvinf; chmod +x cpuvinf; mv cpuvinf /usr/bin/cpuvinf
or


wget http://apps.singul4rity.com/cpuvinf; chmod +x cpuvinf; mv cpuvinf /usr/bin/cpuvinf
Usage:

All you have to do is login as any user and issue the command "cpuvinf" with a parameter to run the script. If the command is issued without a parameter it will display all information at once.

Changelog:

v0.1:
- Initial release

v0.2
- Parameter support for specific output added
- If no parameter is specified everything will be displayed
- volt=1.20V changed to plain and simple 1.20V on output

not cool man. if you want to contribute, than please share it here instead of backlinking to another forum!

As you wish.

The topic has been modified and includes everything you need to know about the tool.

It may not be updated as frequently as it will be updated on FreeVPS Directory & Discussion.

Hey it works, but oddly I have the same value output as the sample screen... time to push the Pi and see what happens...

Very interesting, playing with this now

Thanks for sharing it here: its a nice project I'll test it

Script updated to v0.3 but I can't edit my first post.

Well, so I guess this won't be updated unless I would make a new topic for every version.

 

[fixidixi]

well we should ask @MannDude about that ^^

Post the updates in-line.. living thread.   

I'll ask Mann to give you edit permission for your thread.

What are the new features / updates?

v0.3
- Parameters are now Linux/Unix styled (e.g: cpuvinf -cpu instead of cpuvinf cpu)
- If/else pyramid replaced with case (thanks to Google for the great shell scripting sites)
- CPU temperature also shown in Fahrenheit now

Parameter list:

-cpu - Displays current CPU temperature in °C and °F
-core - Displays core voltage in V
-sd - Displays SDRAM core voltage in V
-io - Displays SDRAM I/O voltage in V
-phy - Displays SDRAM PHY voltage in V
