Ubuntu / Linux news and application reviews.

PiCon is a Raspberry Pi configuration manager which lets you make changes to the config.txt file using a GUI. The config.txt file is used to store various system parameters that you would normally set from the BIOS, but Raspberry Pi doesn't have a conventional BIOS and thus, it uses this file for such settings.

The application is designed to run on a host system (works on Windows, Linux and Mac since it's written in Java) and not directly on the Raspberry Pi. It is possible to run the app on Raspberry Pi, but the performance is pretty bad.

Raspberry Pi Configuration Manager (PiCon) can be used to change settings such as:
  • video output controls: switch between NTSC and PAL, change the aspect ratio, rotate the screen, overscan configuration, enable fixed framebuffer, change the HDMI display modes, force or disable sound, force HDMI 3D support, HDMI boost, use HDMI safe mode and more;
  • overclock the CPU, GPU and SDRam;
  • advanced overclocking: overvoltage the GPU or SDRAM, force turbo, initial (temporary) turbo, change the GPU processor frequency, the hardware video block frequency, 3D block frequency, image sensors pipeline block frequency as well as setting a temperature limit (sets clock and voltages to to default when the temperature reaches a certain value);

To use PiCon in Linux, firstly download and extract the archive in your home directory. Then, put the SD card into your computer, access the boot partition (normally, when you insert an SD card on your computer on which you've installed a Raspberry Pi Linux distribution, two partitions should be mounted: the smaller one - 73 MB for my RaspBMC -, is the boot partition) and copy the config.txt file from this partition into the PiCon folder:

To launch PiCon, use the following command (obviously, make sure you've installed Java before this):
java -jar ~/PiCon*/PiCon.jar

Make the changes you want and click "Save Settings" - this will write the changes to the config.txt file which you must copy back to the SD card boot partition.
