The LEDMATRIX interface News: Now with lcd4linux driver I recently purchased 10 SLM1608 (SLM1606) LED matrix display units from Ebay (you might also contact the seller directly at [email protected]). These are 16×16 LED matrix units with a green and a red LED per pixel allowing each pixel to be switched to either green, red, amber […]

Attach any I2C client chip (thermo sensors, AD converter, displays, relais driver, …) to your PC via USB … quick, easy and cheap! Drivers for Linux, Windows and MacOS available. The i2c-tiny-usb project is an open source/open hardware project. The goal of i2c-tiny-usb is to provide a cheap generic i2c interface to be attached to […]

The Newnes Know It All Series takes the best of what our authors have written to create hard-working desk references that will be an engineer’s first port of call for key information, design techniques and rules of thumb. Guaranteed not to gather dust on a shelf! Circuit design using microcontrollers is both a science and […]

It’s using a two axis acceleration sensor to measure acceleration (caused e.g. by motion […]

The complete WLAN solution for AVR and other CPUsThe page is about equipping an Atmel AVR microcontroller based system with a Prism WLAN interface. This document is intended for people that already have experiences with the AVR microcontrollers and teaches them how to add a cheap but flexible WLAN interface to your AVR projects. Related […]

The following instructions are from early 2007 and are pretty outdated by now. They are still here for reference, but they are not maintained anymore and very likely won’t work with recent versions of MacOS anymore. After having developed software for the AVR under Windows and Linux the only major plattform missing was MacOS X. […]

The NanoVM is a java virtual machine for the Atmel AVR ATmega8 CPU, the member of the AVR CPU family used e.g. in the DLR Asuro robot, manufactured by AREXX engineering. With the NanoVM, the Asuro can be programmed in the popular Java language using the standard Sun JDK. The NanoVM and its tools are […]

Devices The EEprom programmer software supports the following devices. 28C16 28C256 28C17 29C256 28C64 Hardware Diode D1 and resistor R1 provide the VDD isolation when programming the 24 pin devices. The jumper J3 must be shorted for 24 pin devices, and open circuit for 28 pin device programming. Following EEPROMs are pin compatible with their […]

The AVR Microcontroller and Embedded Systems: Using Assembly and C features a step-by-step approach in covering both Assembly and C language programming of the AVR family of Microcontrollers. It offers a systematic approach in programming and interfacing of the AVR with LCD, keyboard, ADC, DAC, Sensors, Serial Ports, Timers, DC and Stepper Motors, Opto-isolators, and […]

In this tutorial we will make a “Digital Stop Watch” using an AVR ATmega8 Microcontroller. This will help you learn many concepts like Multiplexed Seven Segment Display Interfacing Using AVR Timers Using Interrupts And many others too. The code is written in C language for avr-gcc (WinAVR) . Steps to Build the “Digital Stop Watch” […]
