RF Communication Between Microcontrollers – Part I RF Communication Between Microcontrollers – Part I Jul 07, 2009 Avinash RF 28 In many situations a communication link between to devices becomes essential. This communication can be wired or wireless. If two devices are close to each other (like a MCU and a Memory) a wired link is preferred. How ever in many situations two devices are reasonably far apart.
O'Reilly Open Books Project O'Reilly has published a number of Open Books--books with various forms of "open" copyright--over the years. The reasons for "opening" copyright, as well as the specific license agreements under which they are opened, are as varied as our authors. Perhaps a book was outdated enough to be put out of print, yet some people still needed the information it covered.
View topic - LiquidTWI: High-performance LCD library for I2C Backpack Module I like fast things. And I like clean code. Often, the two go hand-in-hand ;) After looking through the modified LiquidCrystal library for use with the i2c backpack and darn near crying when I saw all the faux digitalRead() and pinMode() being done on each transfer, I was bound and determined to never let that happen to another friendly Arduino user again. I first made a proof of concept modification to the library to "burst" all the "LiquidCrystal::send" bits instead of digitalWrite()'ing them out one at a time (read I2C, modify, write... read, modify, write... read, modify, write... read, modify, write - over 16 I2C commands for each single character). It worked great.
Basic Linear Design: Analog Dialogue: Analog Devices Individual chapters--or a zip file containing all chapters--of the original Basic Linear Design seminar notes can be downloaded by selecting the appropriate links below. Cover (pdf, 2690 KB) Introduction (pdf, 115 KB) OSH Park ~ Pricing and Specifications There are currently three types of orders: The standard 2 layer order $5 per square inch, which includes three copies of your design. For example, a 2 square inch board would cost $10 and you’d get three copies of your board.
Circuit Simulator Applet This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage. Online Mathematics Textbooks Professor Jim Herod and I have written Multivariable Calculus ,a book which we and a few others have used here at Georgia Tech for two years. We have also proposed that this be the first calculus course in the curriculum here, but that is another story.... Although it is still in print, Calculus,by Gilbert Strang is made available through MIT's OpenCourseWare electronic publishing initiative. Here is one that has also been used here at Georgia Tech.
i2c / SPI character LCD backpack [v1] ID: 292 - $10.00 LCD backpacks reduce the number of pins needed to connect to an LCD. LCDs are a fun and easy way to have your microcontroller project talk back to you. Character LCDs are common, and easy to get, available in tons of colors and sizes. We've written tutorials on using character LCDs with an Arduino (or similar microcontroller) but find that the number of pins necessary to control the LCD can be restrictive, especially with ambitious projects. CrossWorks for ARM - C/C++ Compiler for ARM and Cortex Microcontrollers CrossWorks for ARM is a complete C/C++ and assembly language development system for Cortex-M, Cortex-A, Cortex-R, ARM7, ARM9, ARM11, and XScale microcontrollers. And when we say complete we mean complete — CrossWorks for ARM is packed full of features such as: CrossStudio Integrated Development Environment which takes care of edit, build, flash download, and debugging over JTAG. C, C++, and assembler toolchain from the GNU Compiler Collection.
Estudio libre en GNU/Linux : GNU/Linux Mi sinte preferido: ZynAddSubFX is a opensource software synthesizer capable of making a countless number of instruments, from some common heared from expensive hardware to interesting sounds that you'll boost to an amazing universe of sounds. The project started in March 2002, and I had written it because I wish to make a synthesizer that produces very beautiful sounds, but which is freely available to anybody who needs it. Features of ZynAddSubFX: - realtime synthesizer - polyphonic (allows playing more than one note at once), mutlitimbral (allows playing more than one instrument at once) synth - Microtonal capabilities with any scale, any number of notes per octave (well... the no. of notes per octave must be less than 128) and keymapping - 3 synthesiser engines: 1) first (called "ADsynth" or "ADnote") is a complex engine which makes sounds by adding a number of voices.
