Raspberry Pi, a small computer powered by ARM architecture is a very interesting board for learning embedded system.

Installing Bodhi Linux on Raspberry Pi

In this article we will discuss about how to install how to install Bodhi Linux Mobile for Raspberry Pi. For this article I use following: Slackware64 14.0Windows 8Raspberry Pi model BBodhiLinux ARM You can use either Linux (in this article, Slackware) or Windows (in this article Windows 8). Just pick one and follow the rest of article for your choice. Obtain the Materials The Operating System images I used is Bodhi Linux for Mobile and can be downloaded from here.

SliTaz armhf: 46MB Linux Distribution for Raspberry Pi. SliTaz armhf is a minimal Linux distribution based on SliTaz Linux, that uses the hard-float ABI for the Raspberry Pi. The compressed SD card image is 46M, the rootfs 18.6 MB, and Slitaz uses just about 7 MB RAM after boot. Slitaz armhf rootfs comes pre-loaded with the following packages: Creating Custom init Scripts. Background Novell/SUSE Linux uses a system of scripts to determine which services to run on system boot.

Creating Custom init Scripts

These scripts exist in /etc/init.d/ (or the symbolic link /etc/rc.d/), and are referred to as 'init scripts.' They help dictate which services are active in each runlevel, and also allow the services to be manually controlled. For more information on runlevels, see this article. Each service that ships with Novell/SUSE Linux installs a script in /etc/init.d/. Increasing Ubuntu Wubi disk image. Invent Your Own Computer Games with Python. Raspberry Pi Challenge.

Magic Wand

So that 1 << 8 will actually generate a number 0x100. The & is the bit wise and operation and is used to probe the individual bits in a byte. So the software will build up an array of bit patterns (numbers) to send to the LEDs in turn. These are then fired at the hardware at a regular rate to produce the flashing pattern we need. This is synchronised to your swing by looking when the motion switch changes direction. Now reliable delays are not a strong point of a multitasking environment like Linux. Also, I think you get better results if you just produce the scan on one swing and not both. Reading Analogue Sensors With One GPIO Pin.

Unlike some other devices the Raspberry Pi does not have any analogue inputs.

Reading Analogue Sensors With One GPIO Pin

All 17 of its GPIO pins are digital. They can output high and low levels or read high and low levels. This is great for sensors that provide a digital input to the Pi but not so great if you want to use a sensor that doesn’t. Basic Resistor Sensor Reading on Raspberry Pi. We've already covered how to use an Analog-to-Digital Converter chip with a Pi.

Basic Resistor Sensor Reading on Raspberry Pi

These chips are the best way to read analog voltages from the Pi. However, there's a way to read many sensors without an ADC! By measuring the sensor as a resistor that is used to 'fill up' a capacitor, we can count how long it takes. It's not nearly as precise as an ADC and its a little flakey (since it depends on the Pi timing itself which can vary based on how 'busy' the computer is) The way we do this is by taking advantage of a basic electronic property of resistors and capacitors.

R-Pi Troubleshooting. Back to the Hub.

R-Pi Troubleshooting

This page lists the most common problems and suggests some solutions. See RPi_Bugs for problems that are bugs. Power / Start-up Note: if you have any kind of booting problems, start off by reading the "Is your Pi not booting? (The Boot Problems Sticky)" in the troubleshooting section of the Official Raspberry PI forum [1]. A good power supply that will supply 5 volts and at least 1 amp (5V 1A) is vital. Note that the Pi has no BIOS, so nothing will be displayed on screen unless the Pi successfully boots! Normal LED status. The MagPi.
