Debugging a program on the stellaris launchpad board | Scompo Projects
OpenOCD now supports TI’s stellaris launchpad. Patching it it’s no longer necessary! The source it’s available here ! After creating a template for the Stellaris Launchpad, I wanted to debug it and my own programs as well. So I installed openOCD and used gdb (for arm-none-eabi) to debug it and see if it works properly.From Texas Instruments Embedded Processors Wiki Translate this page to Version 1.10 March 2013 Labs are based on CCS 5.3 Introduction The Getting Started with the Stellaris EK-LM4F120XL LaunchPad Workshop is a free, in-depth, hands-on introduction into Stellaris LM4F basics including: Introduction to the ARM® Cortex™-M4F and Peripherals Introduction to Code Composer Studio StellarisWare, Initialization and GPIO Interrupts and the Timers ADC12 The Hibernation Module USB Memory The Floating-Point Unit BoosterPacks and the Graphics Library Synchronous Serial Interface (no video yet) UART (no video yet) uDMA (no video yet)

ARM Cortex-M4F based development board from Texas Instruments.Description: The UBW board is a small board that contains a Microchip PIC USB-capable microcontroller, headers to bring out all of the PICs signal lines (to a breadboard for example), only costs about $15-$20 to build and is powered from the USB connection. I designed this board to be a simple parallel port replacement tool for Bruce Shapiro for use in his bits-to-bytes-to-bots class. Apologies to all other 'Whacker' projects like EDTP's Packet Whacker for stealing a great name <grin>. All tools used to design this project are free, and the design is open to anyone to use for whatever they wish. Please build your own and improve upon it!
UBW (USB Bit Whacker) Project
To change our opcodes to hex file format we need to (1) pad to 8-bit boundary, (2) convert to hexadecimal, (3) change the byte endian and (4) consider where to put our program. We have explained most of these changes in the previous section The configuration words . We have to consider where to place the program inside the PICs flash memory.

Billiard ball computer
A billiard-ball computer , also known as a conservative logic circuit , is an idealized model of a reversible mechanical computer based on Newtonian dynamics , proposed in 1982 by Edward Fredkin and Tommaso Toffoli . [ 1 ] Instead of using electronic signals like a conventional computer , it relies on the motion of spherical billiard balls in a friction-free environment made of buffers against which the balls bounce perfectly. It was devised to investigate the relation between computation and reversible processes in physics. [ edit ] Simulating circuits with billiard balls

ChipKIT Challenge | Watt Circuit Blog
So, we have finally finished our entry, a few hours before the deadline! The competition is about building an eco friendly or renewable based circuit that uses a ChipKIT board, and is run by designspark, Elektor and Circuit Cellar. We built a maximum power tracking circuit, which performs impedance matching to transfer power out of a source efficiently. Basically all energy sources have some resistance as part of their construction (like the internal resistance ), and we make sure that our circuit presents a load to the battery which wastes the least power.SecretsOfArduinoPWM
Learning Examples | Foundations | Hacking | Links Secrets of Arduino PWM by Ken Shirriff with further editing by Paul Badger the original document Pulse-width modulation (PWM) can be implemented on the Arduino in several ways. This article explains simple PWM techniques, as well as how to use the PWM registers directly for more control over the duty cycle and frequency. This article focuses on the Arduino Diecimila and Duemilanove models, which use the ATmega168 or ATmega328 .
Introduction This mini Logic analyzer is a tool for you to watch on LCD the logic transitions 0 or 1 of a digital data signal. A digital data signal can be found on the output pin of TSOP-1730 Infrared Receiver, on the Transmit and reveive pins of MAX-232 chip (RS-232), on Clock and Data pins of I2C data bus and many more electronic components. This circuit supports capturing for up to 100 kHz digital signals. Schematic of the circuit. Description

ELECTRONICS - THE KING OF HOBBIES!: Multitasking in AVR (A demo to run 7 tasks on an atmega32)
.INCLUDE "m32def.inc" .ORG 0x0000 rjmp startup .ORG 0x000e rjmp context_switchThe Science Tricorder Mark 2 was a wonderful adventure of discovery to develop. It's my pleasure to be able to share it with you. To introduce you to the Tricorder project, I'd like to begin with a story from the development of the very first Tricorder that I built. The first educational discoveries with the Tricorder came only moments after completing it, and walking about the workshop to "see what can't be seen". Upon holding the Tricorder near a power adapter plugged into the wall, you could see the oscillating magnetic fields on the magnetometer visualization.

If you have ever managed to break your XBee module, then fear not! A simple re-flash has worked for me many times. This has certainly worked a couple of times from my Series 1 radios. But I don't see why it wouldn't work for a Series 2.5 radio! Here's how: Connect a wire to pin 5 (reset) and leave the other end floating for now Open X-CTU On the 'PC Settings' tab, tick the 'No baud change' box On the 'Modem Configuration' tab, select the appropriate settings (In my case XBP24, Version 10CD) Tick the 'Always write firmware' box Click 'Write' It complains because your XBee is dead!
