This article shows how to do a simple communication via a RS232 interface with a PIC microcontroller. RS232 is a standard for a serial communication interface which. Project Moved. New home (starting with V3.0): moved to github: https://github.com/pyserial/pyserial; docs: https://pyserial.readthedocs.org/en/latest/. Ontrak Control Systems manufactures serial ( RS232, RS485, USB) Data Acquisition and Control Interfaces. The purpose of a null-modem serial cable is to permit two RS-232 devices to communicate with each other without modems or other communication devices between them.

Windows Serial Communications component library for C/C++. C++ developer tool for serial port communications programs; Supports RS232, multidrop RS422 and RS485 ports.

The easiest way to access COM ports in Visual Basic 6 is by placing the Microsoft Comm control on a form, and writing code to read and write each serial port.

Microchip PIC micros and CC sample code for PIC micros and Hi- Tech CSample projects for the Microchip PIC micro series of microcontrollers, including the PIC1. PIC1. 6x, PIC1. 8x, PIC2. PICx microcontrollers.

This project is a modified form of the CDC (Communications Class Driver) available from www. The www. htsoft. com forum has some discussion on this code. Note: ensure that you read . Schematics: this code runs on the PICDEM- FS board from Microchip. To make your own schematic, place a PIC1. F4. 55. 0 on a breadboard, ensure that you are using a 2. Mhz crystal, place a 4.

F capacitor on port Vusb, and hook the USB directly to the chip. It should start to work straight away. Download the PICDEM- FS datasheet for the exact schematic to use with this code.

Result: start up Hyper. Terminal or putty, find the new COMx port that has been enumerated. Set it to 1. 15. 20. N,8,1. The actual COM port speed doesn't matter, as its a virtual comm port. You will see . You can find the exact number of the virtual COM port by going into . You can change the number of the virtual comm port by going into properties, and selecting the new COM port.
