How to send and receive data from RS232 to PIC16F877? Is there any suggestion for the circuit and sourcecode?

ryusgnal,

I have something writen at Borland C++Builder 5.03.
If you want, I may post it here, or send to you.

download interfacing rs232 to pic16f877

You can use Visual Basic 6.0 to make GIU interface which is very simple. Firmware can be done by using USART module in PIC16F877. Good luck.

How about the C program for RS232 with PIC18F4550?

Hi,
you can use the UART rx/tx of pic16f877.
check the pic16f877 datasheet, where you find out the pins of UART...

The best and easy software is the c language for PIC microcontroller, CCS C PIC, or HITECH.
For PC, the visual basic is the best and easy way to comunicate with PIC16F877.

GOOD luckl

Hi,
You can check this example

Do you have this example in visual C version?

@ryusgnal

vISUAL c++ is for PC... you need one compiler for a uC.

I mean instead of using VB for interface. I prefer to use visual c++ because I'm not very good in VB and nobody can guide me in VB.

In vb example mscomm activex is used for serial comm.

To see how to use it in VC++ check this link

you should know about 9 pin and 25 pin RS 232 data traveler serial port data sheet
so download it and try to program in VB.net

I think you should check Microchip website. It is a general question.

Use a solderless breadboard or a pcb from Olimex.com. You will need a 16F877A , St232A and a power source. For the power source you could add your own with a 7805 regulator and a wart. Check Futurlec.com or mouser.com for parts and datasheet downloads. Connect the st232A output/inputs to the RX and TX pins on the 16F877A. Download the ST232A datasheet from mouser or www.stm.com

Next goto Oshonsoft.com and download the Pic-Simulator which includes a basic compiler. It also has a PC com port interface to talk to the 16F877A. You could also use any number of terminal emulators available on the internet. Use Google.

If you're willing to spend some money buy a PicKit2 from Microchip ($40.) and the Pic-Simulator (29 euro). If you want to make life very simple also use the bootloader on the Oshonsoft site. See projects.

I encourage everyone to take a look at http://www.piclist.com/techref/piclist/index.htm
You'll find there a plenty of resources and materiels related to PIC µC.

use the inbuilt function

#use RS232(BAUD=9600, XMIT=PIN_C6, RCV=PIN_C7)
output_c (0x40); //RC6/TX RS232 =1
SET_TRIS_c(0x98);

easy & fast
