Code and Life - Joonas Pihlajamaa

He has a Embedded Systems Programming Blog where you can read and learn programming for the small SBCs and Testing Chips on "USB Stick SBCs" that are now a standard.

He has useful tutorials on V-USB which is a software-only implementation of a low-speed USB device for 's AVR microcontrollers.

He also has many ideas on PC Interface Hardware and Code that may help Home Automation Projects. He reviews embedded starter evaluation boards. Many ideas on Audio and Video using these uC boards.

"All that was needed between the two devices was some jumper wire and two 1 kOhm resistors to form a voltage divider between Arduino TX pin and Pi RX pin – Arduino understands Pi’s 3.3V signal levels just fine so Pi TX to Arduino RX needed no voltage shifting at all."

Open source Wireless sensor platform - Waspmote

Waspmote may have two radios at the same time connected when using the Expansion Radio Board allowing the creation of bridges among different networks such as ZigBee and Wifi, Wifi and 3G/GPRS, RFID and Bluetooth, etc.

"The idea behind the Raspberry Pi to Arduino shields connection bridge is to allow to use any of the shields, boards and modules designed for Arduino in Raspberry Pi. It includes also the possibility of connecting digital and analog sensors, using the same pinout of Arduino but with the power and capabilities of Raspberry."

Running BitScope on Raspberry Pi

Create a complete stand-alone mixed signal oscilloscope, logic analyzer, spectrum analyzer and waveform generator. This tiny BitScope is USB powered by the Raspberry Pi and can be used with BitScope DSO which runs directly on the Raspberry Pi.

BitScope 10 is very low power. Unlike a lot of other gear, this means you don't need a USB hub. Simply connect directly to the Raspberry Pi, add a monitor and mouse, and you're good to go.

Breadboard One - A typical Mixed Signal Circuit

The first BitScope Ed project, a simple mixed signal circuit which explains the key elements of modern mixed signal systems. Electronic Projects Lab for Raspberry Pi based on Breadboard One to test the circuit.

This arrangement provides the power supply, waveform generator, clock generator. Even tools like a frequency meter or volt/Amp meter. Connections made via its Smart POD Interface. Breadboard One connects directly but logic probes or analog probes like DP01 can be used too. Some BitScopes have BNC inputs for use with standard oscilloscope probes.

Raspberry Pi - ARM with Linux Nano Computer

Raspberry Pi is a Miniature Computer that can Interface with a Display Device like TV and a keyboard.

Raspberry Pi - ARM with Linux Nano Computer

Learning Programming with DIY Computing

We now also have a tiny ARM SoC mini computer called Raspberry PI which helps you know how a computer works. Browse the Internet on your TV or learn coding in many programming languages.

(These ARM based devices power many of the small portable electronics we see today.)

Model A has been redesigned to have 256Mb RAM, one USB port and no Ethernet (network connection). Model B has 256Mb RAM, 2 USB port and an Ethernet port.

The SoC is a Broadcom BCM2835. This contains an ARM1176JZFS, with floating point, running at 700Mhz, and a Videocore 4 GPU. Overall real world performance is something like a 300MHz Pentium 2, only with much, much swankier graphics.

There is composite and HDMI out on the board, so you can hook it up to an old analogue TV, to a digital TV or to a DVI monitor. No VGA support.
