Rs-485 Isolated Interface

An IDE interface board is currently being developed, along with driver software to support reading and writing on a hard drive under the OS-X 2.0 RTOS. An assembled IDE interface board is available for reference. The PCB layout files...

74hc573 is used to store data so that the previous content on SS is not vanish when we disable LE pin. T0 select the proper latch 74hc238, 3x8 decoder is used. And to convert BCD into decimal, 74ls48 converter...

Many RS-485 and RS-422 networks require isolation for safety, noise reduction, or ground loop elimination. A conventional circuit is shown in Figure 1. Unfortunately, optocoupler isolation is slow, complicated, and unreliable. Although RTS does not require the same speed...

The circuitry of the ZXInterface2 is straightforward, consisting of a single custom-made integrated circuit (IC) that handles address decoding for the dual joystick interface. The ROM cartridge socket provides access to signals already present at the Spectrum's edge connector....

Several possible interface circuits are presented for use with a remote-control transmitter. The circuit labeled A demonstrates a typical FM stereo MUX decoder with a load connected directly to the open-collector output of a TA7343 PLL. The circuit labeled...

Alphanumeric LCD displays are widely used in microcontroller applications due to their versatility and ability to enhance project functionality. They provide text messages that offer user instructions and feedback, contributing to a more professional and user-friendly experience. LCDs are...
