Texas Instrumentsâ buffer features stuck bus recovery Texas Instrumentsâ TCA4307 is a hot-swappable I2C bus buffer that supports I/O card insertion into a live backplane without corruption of the data and clock lines. Control circuitry prevents the backplane-side I2C lines (in) from being connected to the card-side I2C lines (out) until a stop command or bus idle […]

Introduction Even in a digital world, classic analog clocks have a timeless style. This simple but universal technology is presented in the article. The implemented project uses a dual-rail GreenPAKâąÂ SLG46121 which can perform all the active electronic functions needed in an analog clock, including motor driver and crystal oscillator. Additionally, GreenPAK ICs are low-cost and tiny

Most microcontroller implementation these days, use the traditional capacitor + crystal approach to generate their clock, this approach sometimes, however, lead to problems, especially when used in prototyping situations with a breadboard, jumper wires, etc., all of which have an (unknown) inherent capacitance that could lead to the clean 8 or 16MHz signal we desire,

DC motors are the most widely used motors. These motors can be found almost everywhere from small projects to advanced robotics. We previously interfaced DC Motor with many other microcontrollers like Arduino, Raspberry pi and used it in many robotic projects. Today we learn to control DC motor with AVR Microcontroller Atmega16. But before going ahead letâs know more about

When working on projects with computation-intensive routines and (or) near real-time performance requirements, having a âlightning-fastâ RAM is usually a good thing for developers. This is one of the reasons while STMicro included the Core Coupled Memory (CCM) RAM in a good number of its STM32 microcontroller series, and Dim Tass recently demonstrated how to use it, in a blog post

Stephen Holdaway recently announced his project, a beautiful vintage VQB71 7-segment display based GPS Clock. Inspired by the fantastic appearance of the LEDs, Holdaway explains that the clock was built with a handful of vintage VQB 71 seven-segment LED displays and an u-box NEO-6M GPS module. âThere are only so many applications for a 7-segment display

Clock generator I recently build a pulse generator and it does its job well. It produces pulses of variable length and at several frequencies. But the number of frequencies it can produce is limited and for many jobs the length of a pulse is less important than its frequency. E.g. when you are testing a
