The example program contains an endless do-nothing loop. The chip’s data sheet details the functions of the register bits. In the PIC, several registers enable the port, set the bit rate, and store received data and data to transmit. NET project to use with it are available from and my website, .)

Listing 1 is PICBASIC code that configures the PIC’s serial port and runs the main program loop. Plus, the number of microcontrollers with embedded serial ports is much greater than those with embedded USB controllers. The program code to access a serial port is less complex than what’s required to communicate via USB. Why use a serial port and not USB? Serial ports are a good choice when you want to keep things simple and inexpensive. With a probe on pin 2 of each connector on the cable, the resistance should measure close to zero. To connect a PICDEM 2 Plus board to a serial port on a PC, use a straight-across cable, not a null-modem cable or adapter, which swaps the lines in the cable. USB/RS-232 adapters are also available with these connectors. Most RS-232 serial ports on PCs have male 9-pin D-subs. The board has a 9-pin female D-sub connector for the RS-232 cable. On the board, the PIC’s serial port interfaces to a MAX3232 chip, which converts between the PIC’s 5V signals and RS-232 voltages.

I ran the code on Microchip’s PICDEM 2 Plus development board. PORTC.6 (TX) is the serial output, and PORTC.7 (RX) is the serial input. The chip’s EUSART manages serial communications and supports an asynchronous mode that is compatible with serial ports on PCs. Like many PICs, the PIC18F4520 has a built-in serial port. I wrote the code in this article for a PIC18F4520 microcontroller.

I’ll also show how to use an RS-422 interface to create serial links as long as 4000 ft. The program detects received commands, takes requested actions, and sends responses. This month I’ll show a companion PICBASIC PRO program for a PIC microcontroller. I described a Visual Basic application that sends commands and receives responses from a device connected via a serial port. NET to transfer data via a PC’s serial ports, including USB virtual COM ports. Last time I showed how to use Visual Basic.
