since the RS232 port is not availible in most of the PC and laptop, modify the RS232 signal to USB com port TTL signal for easy access during my teardown, the UT61D uses main chip FS9922-DMM4, where ...

Abstract: The purpose of this paper is to outline a universal RS232-to-GPIB interface which can enable a computer with an RS232 serial port to be a GPIB Talker or GPIB Listener and has the capable of ...

わけあってRS232とEthernet変換機が必要だったんですが、買うと結構高いので、ちょうど我が家に眠っていたArduino Nano Everyを使って作ってみました。実際は、ちょっと単なる電文のやり取りじゃなくて、ちょっとだけ文字列操作が必要だったんです。 GitHubに ...

The project provides the conversion between an RS232 serial interface and an SPI interface which uses the SSP port on a 16F819 device. It is possible to send any sequence of bytes on the SPI interface ...

A web interface, and command line tools for controlling a Monoprice 4x4 HDMI Switch (Version 3.0) via the RS232 Serial port on a Linux/Unix/Mac system. Using Command ...

The microchip PIC microcontroller incorporates an I2C interface on one side using bit-banging on a 12F675 device and an RS232 serial interface on the other. The RS232 in this device refers to ...

Dozens of serial data interfaces are used today. Most have been developed for specific applications. A few have become universal, such as I 2 C, CAN, LIN, SPI, Flex, MOST, and I 2 S. Then there’s ...
