Michele Costantino EDN This Design Idea describes a simple and effective way to provide optoisolation for devices connected on the I 2 C bus (Figure 1). It improves on an earlier version (Reference 1). SDA and SCL are on the bus master’s side ...

Dan Meeks EDN Most current microprocessors, DSPs, and field-programmable gate arrays integrate hardware and software resources that support either or both of two common interface standards SPI (serial-peripheral interface) and I 2 C ...

The ubiquitous LCD (Figure 1) (and VFD) modules based on the HD44780 controller IC can require up to 12 lines from the host. Figure 1. A typical LCD module. This hardware interface Design Idea (Figure 2) reduces the connection to just one wire, ...

Ryan Metivier, Analog Devices EDN Home-based power-line networking signals are similar to xDSL (digitalsubscriber- line) signals in that they both typically employ a form of OFDM (orthogonal frequency-division multiplexing). Both applications ...

I stood in stunned silence at the smoke billowing up from the hardware on the workbench. Just moments before, it had been operating as expected, before self-destructing with a sound that can only be compared with a gunshot. The failure of the ...

Girish Choudankar Electronic Design The 1-Wire interface is low-cost and effective, but useful only for a very short distance; by using a standard bus-buffer IC, this distance can be extended while creating a convenient interface to a ...

By Darwin Tolentino The controller area network (CAN) serial-bus topology allows devices and microcontrollers to communicate with each other without the use of a host computer. Featuring arbitration-free transmission, it places a controller and a ...

Reference Design APP 5610 December 2013 Yuriy Kurtsevoy, Stuart Smith This reference design shows how to develop a high-performance, high-voltage 2- or 3-wire 4­20 mA current-loop transmitter suitable for industrial process control and smart ...

Application Note AND9149/D August 2013 NCN5120 is a receiver-transmitter IC suitable for use in KNX® twisted pair networks (KNX TP1-256). It supports the connection of actuators, sensors, microcontrollers, switches or other applications in a ...

Part 1 - Schematic Part 2 - Software Optimising the line drawing algorithm The first versions of my driver code featured the Extremely Fast Line Drawing Algorithm (EFLA). It seemed to perform well and so I didn’t turn my attention to ...
