Rex Niven EDN 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 ...

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 ...

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 ...

Part 1 - Schematic The software drivers My previous Nokia QVGA reverse engineering efforts that you can find documented extensively on this site have left me with a flexible and expandable driver that will make a good base from which to add support ...
