![]() The specific baud rate of 9600 Bits Per Second (BPS) means we will have to do someĬalculations when setting up the PIC microcontroller. Receiving works as described, it means we have a valid RS232 interface. Specific LEDs when commands are sent to it over RS232, then the PIC should send the same command back to the computer after execution. The PIC will be interfaced to a standard Laptop via RS232 Serial communication. Standard baud rates should be used (9600 bps). The goal of this project is to build a communications interface that both sends and receives information orĬommands over RS232. The error checking functionality is not as necessary as it once was, due to better qualityĪ Simple RS232 Serial Communication Interface It has been simplifiedĭown many times so that only 3 pins are needed Transmit, Receive and Ground. ![]() The RS232 standard that exists today has changed dramatically, in a good way. An early form ofĭigital communication was given the standard name RS232 and it was used in the 1960's with Teletypewriters, often used by police to look up records on arrested All modern computers use a variety of different methods to communicate information. ![]()
