Thank you guys so much for your helping @zan I tried your circuit agian, it is work with me perfectly. My problem was that sending data from USART Terminal but now I tried to send data from Virtual Terminal from Proteus as you siad. I forgot to tell you that I use Virtual Serial Port Driver as you ...

This code says if you send 'a' or any data from PC to PIC, PIC will send same data from PIC to PC. Please, don't forget that you are working in Proteus, so if you send 'a' from virtual terminal to PIC, the PIC will return 'a' to virtual terminal. I send data from USART Terminal in MikroC Pro to PIC...

I tried it but nothing happened. Also How you want PIC send data without COM ? in your connection no sender and no reciever. This code says if you send 'a' or any data from PC to PIC, PIC will send same data from PIC to PC.

You should work with Vurtual Terminal or Compim component. You can not use both of them like you did. Also, TX pin from PIC, need to be connected with RXD pin, and RX pin to TXD pin. Thank you zan for your reply if I connnect TX pin from PIC to RXD not work (I don't no why?) I searched in web about...

Hello for all, I want send data (letters or numbers) by USART Terminal tool in MikroC Pro This is my code ( example from help file in MikroC Pro ) char uart_rd; void main() { ANSEL = 0; // Configure AN pins as digital ANSELH = 0; UART1_Init(9600); // Initialize UART module at 9600 bps Delay_ms(100)...

Hello Eng_Bandar, I think the problem could be in port assignement, I mean, you configured COM2 port in ISIS, then you configured COM1 in MATLAB, and I suppose both programs are going to send data via the same physical port right?, am I right? No, I think problem not from that because must find sen...

Hello braus,

Thank you braus for your helping.

the problem not solved.

Did you see the video ?

Hi all, I work now in a project contains Matlab, Porteus, MikroC Pro and Virtual Serial Port Driver. My project if I send 'g' letter to PIC 16F877 LED will be turn on. Unfortunately LED not work. I don't know where is the problem. MikroC Pro Code char data_1; void main() { trisd=0; // all portb are ...

^^^^^^^^^
Thank you for your helping

my project if I send letter G from computer to pic led will on and this is my code char data; void main() { trisb=0; // all portb are output UART1_Init(9600); // speed is 9600 while(1) { if(UART1_Data_Ready()==1) { // when receiving data data = UART1_Read(); // read data and store it in variable if(...
