Extensible Multiple Device Programmer 4 Base
The 5-volt microcontroller interfaces with the RS-232 serial connector and the USB-B connector. It is responsible for communicating with the checker, controlling the status LEDs, and setting the voltage for the low-voltage microcontroller. The low-voltage microcontroller operates at the voltage...
Rs232-to-cmos-line-receiver
This RS-232 type line receiver is designed to drive CMOS logic and incorporates a Schmitt-trigger feedback network that provides approximately 1-V input hysteresis, enhancing noise immunity. A potential issue in an interface connecting two devices, each connected to different AC...
How to get power from RS-232 port
This text aims to clarify how to extract power from a PC serial port. Many small circuits derive their operating power from the serial port, despite the absence of dedicated power output pins. Examples of such circuits include PC mice...
DS1621 IIC interface under Linux drives designing
The IIC bus line is a type of communication protocol that facilitates the transmission of data between devices. It is characterized by its simplicity in construction and wiring, making it suitable for various high-performance applications. The operating system, particularly Linux,...
i2c interface to USB interface
The i2c-tiny-usb project is an open source/open hardware project. The goal of i2c-tiny-usb is to provide a cheap generic i2c interface to be attached to the usb. It is meant as a replacement for those simple and cheap printer port...
SPI Interface Big 7-Seg LED
The circuit is an easy-to-build and use general-purpose Big LED with SPI serial interfacing. It is expandable for multiple digits while utilizing only three wires to receive data from any microcontroller boards. The design incorporates a serial-in-parallel-out shift register, the...
