midi interface

This page describes how to build this full-bandwidth single-port (one input and one output) MIDI interface. The interface is buffered (that is, if the PC gets behind you won’t lose data) and it works in Windows 3.1 and Windows...

This interface circuit provides electrically isolated RS422 communication interface to the PC serial port. The isolation circuit protects the PC from direct connection to hazardous voltages. More: Figure 1 shows the circuit diagram of RS422 interface. Connector K1 is...

The FTDI DLP-USB245M is a USB-to FIFO interface module that simplifies the control of multiple stepper motors by a PC. The FTDI DLP-USB245M module is designed to facilitate communication between a PC and various electronic devices, specifically enabling the control...

The circuit features a serial coded modulated control signal that amplifies and transmits high-voltage isolation. It utilizes a 556 timer-based circuit along with resistors R1, R2, capacitors C1, and R3, R4, C2 to form two astable multivibrators. The circuit...

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...

This document provides information for developing a Vehicle Accessory Computer Interface (VACI). The project involves a straightforward design that required approximately three weeks of planning, programming, and debugging. The interface has garnered significant interest, with many users expressing a...
