MPLAB for the Arduino User – Digilent Inc. Blog

I recently had to take a sojourn from the comfortable Arduino IDE to the relatively foreign work-space of MPLAB X IDE. It was a brief trip; just long enough to figure out how to blink an LED on board my chipKIT DP32, but it left a lasting impression that’s given me a greater appreciation for the Arduiino IDE. #include <stdio.h> #include <stdlib.h> #include <p32xxxx.h> int main(int argc, char** argv) { int i = 0; TRISBbits.TRISB2 = 0; while(1) { LATBbits.LATB2 = ~PORTBbits.RB2; for(i = 0; i < 10000; i++); } return (EXIT_SUCCESS); } The code above is the cut-down, uncommented version of my simple LED blinking program, written in the MPLAB X IDE.

How to choose a flyback diode for a relay? Why don't relays incorporate flyback diodes? Relay's Flyback Diode - Is it necessary? Select the Right Varistors for Overvoltage Circuit Protection. Varistors, also called metal-oxide varistors (MOVs), are used to protect sensitive circuits from a variety of overvoltage conditions.

Select the Right Varistors for Overvoltage Circuit Protection

Essentially, these voltage-dependent, nonlinear devices have electrical characteristics similar to back-to- back Zener diodes. Download this article in .PDF format Voltage TransientsVaristors feature high durability, which is essential for withstanding repeated high-peak pulse currents and high-energy surge transients. They also offer a wide voltage range, high energy absorption, and fast response to voltage transients. Peak current ratings range from 20 to 70,000 A, while peak energy ratings range from 0.01 to 10, 000 J. In this context, “voltage transients” are defined as short-duration surges of electrical energy. . • Lightning: In fact, transients induced by lightning are not the result of a direct strike.

OpenScope MZ: Open-source All-in-one Instrumentation - Digilent. As seen on Kickstarter!

OpenScope MZ: Open-source All-in-one Instrumentation - Digilent

OpenScope MZ is a portable multi-function programmable instrumentation module. What does that mean? It's a device that you connect to your computer (through WiFi or a USB cable) that allows you to acquire, analyze, visualize, and control signals from circuits, sensors, and other electronic devices. Unlike typical USB instruments, OpenScope MZ can also be programmed to run standalone like an Arduino or Raspberry Pi, but with high-speed precision analog and digital I/O. At the core of the OpenScope MZ is a powerful Microchip PIC32 MZ Processor. A tiny USB Mixed Signal Oscilloscope. They don't come any smaller than this!

A tiny USB Mixed Signal Oscilloscope

Just like BS10 this is a fully featured mixed signal test & measurement system, a mixed signal scope in a probe! 20 MHz Bandwidth. 40 MSps Logic Capture. 2 Analog Scope Channels. 2 Analog Comparator channels. 6 Logic/Protocol Analyzer channels. 8 & 12 bit native analog sample resolution. Decodes Serial, SPI, I2C, CAN and more. Windows, Linux, Mac OS X & Raspberry Pi. Built-in analog waveform & clock generators. We call it BitScope Micro, a go anywhere problem solver that fits in the palm of your hand.

Home - Correlated Magnetics. Serial Terminal Basics. Favorited Favorite 7 CoolTerm is useful no matter which operating system you’re using.

Serial Terminal Basics

However, it is especially useful in Mac OS where there aren’t as many terminal options as there are in Windows. You can download the latest version of CoolTerm here. Making a Connection Download and open a CoolTerm window. To change the settings, click the Options icon with the little gear and wrench. Here, you can select your port, baud rate, bit options, and flow control. Now click on the Terminal tab on the left.

Here, you can change the enter key emulation (carriage return/line feed), turn local echo off or on, and you can switch between line mode and raw mode. Once all your setting are correct, the Connect and Disconnect buttons will open and close the connection. If you need to clear the data in the terminal screen, click the Clear Data icon with the large red X on it. Extended Features One awesome feature of CoolTerm is Hex View. Here I’ve typed hello and <enter>.

Learn about switch basics, including the pole and throws naming convention, normally open (NO) and normally closed (NC) terminology, different switch topologies, and types of switches such as electromechanical relays, reed relays, solid state relays, and field-effect transistor (FET) switches.

Switch Types and Common Terminology

This tutorial is part of the Instrument Fundamentals series. 27800 Parallax. Diegotrap/electronics. Negative Feedback and Negative Feedback Systems. Negative Feedback Systems Negative Feedback, NFB is the most common form of feedback control used in process, micro-computer and amplifier systems.

Negative Feedback and Negative Feedback Systems

Feedback is the process by which a fraction of the output signal, either a voltage or a current, is used as an input. If this feed back fraction is opposite in value or phase (“anti-phase”) to the input signal, then the feedback is said to be Negative Feedback, or degenerative feedback. Negative feedback opposes or subtracts from the input signals giving it many advantages in the design and stabilisation of control systems. For example, if the systems output changes for any reason, then negative feedback affects the input in such a way as to counteract the change. Feedback reduces the overall gain of a system with the degree of reduction being related to the systems open-loop gain.
