CrossPack - A Development Environment for Atmel’s AVR Microcontrollers
CrossPack is a development environment for Atmel’s AVR® microcontrollers running on Apple’s Mac OS X, similar to AVR Studio on Windows. It consists of the GNU compiler suite, a C library for the AVR, the AVRDUDE uploader and several other useful tools. Features Does not depend on Xcode for building AVR code. Runs on Mac OS X 10.6 and higher. For a list of included software packages and versions see the Release Notes. Getting Started Since CrossPack consists of command line tools only (except the HTML manual which is linked to your Applications folder), you need to know some basic command names. bash$ cd Desktop bash$ avr-project Demo bash$ cd Demo bash$ ls -l total 0 drwxr-xr-x 3 cs cs 102 Nov 22 18:29 Demo.xcodeproj drwxr-xr-x 4 cs cs 136 Nov 22 18:29 firmware bash$ cd firmware bash$ ls -l total 24 -rw-r--r-- 1 cs cs 4139 Nov 22 18:29 Makefile -rw-r--r-- 1 cs cs 348 Nov 22 18:29 main.c Now we compile the code and send it to the device: That’s it.
Zener Diode Circuits and Applications
- a summary or tutorial covering the essentials of the Zener diode or voltage reference diode used in many power supply and other circuits. Zener diodes are used in many circuits in a variety of ways. The most common Zener diode circuit is one in which the Zener diode is used as a voltage reference element. This type of circuit uses the constant voltage as a reference in one of a variety of forms of power supply circuit. There are other Zener diode circuits and applications. Simple Zener diode ciruit for voltage regulator When used in a regulator cirrcuit, the Zener diode must have the current entering it limited. In a practical circuit, the simplest form of current source is a resistor. Simple circuit of a Zener diode shunt regulator The value of the series resistor is simple to calculate. Resistor value (ohms) = (V1 - V2) / (Zener current + Load current) Where: V1 is the input voltage V2 is the Zener diode voltage Zener diode circuit for PSU with series transistor Circuit tips By Ian Poole

595 Shift Register Simulator | ConductiveResistance
For beginners, the 595 series Shift Register isn’t easy to grasp. I’ve written an interactive 595 simulator so you can learn out the 595 works without having to wire one together. Play around with it. I would recommend the most recent versions of Firefox, or Safari “Wait a minute! Picture a box that has a hole on either side. That’s kind of how a shift register works. Try the following: Click the Serial Input Toggle button so that the SER pin goes red (that means it’s “HIGH”)Click on the Clock button (Notice the SRCLK pin goes HIGH)Now look at the Storage Register on the right. Now try those steps again, except press the Latch button after each Clock press. Here are a couple of characters for the 7-segment display to get you started: At least one person was looking for part numbers for 595 shift registers. What’s the difference? If you’re looking for one and aren’t sure where to start, I’d recommend going to SparkFun.

In the beginning, there are breadboard prototypes. An examples looks as below: Breadboard wiring is often done with so called "jumper wires". Jumper wires can be as simple as simple wires. Jumpe wires often come with headers, and for breadboards, wires with male type headers often make sense. Well, breadboards are just lo-fidelity prototypes. For example, in the case of combining a LEDlogics with an Arduino Micro, a setup with male headers on the PCBs and female headers on the wires looks like this: The combination of male header connectors on the board together with female headers on the jumper wires is also a popular option for most breakout boards, for example see the following Nunchuk break out board: If you think about advanced wiring of digital systems, things get quickly more complicated. An example is here wiring up an old joystick with an RS-232 interface. Connectors on ribbon cables are another topic. For sure, wiring is an interesting and important part of electronic projects.
