EUSART for Pic16f1937

[mina.tawfik]

I am trying to send and recieve data from PIC16f1937 to PC via RS232 . can any1 send a sample MikroC code of how to initialize and send texts and communicate with the PC
thnanks

Hi,

Please, try this code :

Code: Select all

char uart_rd;
unsigned int i;

void main() {
  ANSELA = 0;                     // Configure AN pins as digital
  ANSELB = 0;
  ANSELD = 0; 
  ANSELE = 0;

  UART1_Init(19200);               // Initialize UART module at 9600 bps
  Delay_ms(100);                  // Wait for UART module to stabilize

  UART1_Write_Text("Uart1 start");

  while (1) {                     // Endless loop
    if (UART1_Data_Ready()) {     // If data is received,
      uart_rd = UART1_Read();     // read the received data,
      UART1_Write(uart_rd);       // and send data via UART
    }
  }
}

Regards,
Filip.

it didnt work at all ... I thinks the EUSART has a different way to initialize it and use it

Hi.

I have a similar problem. I hadn't been unable to initialize the EUART2 of pic18f66k90 , and I followed your advice to put instead of 9600 bps 19200bps . This worked !! but now my problem is that I have an enabled port to 19200 bps when in fact I need to have a speed of 9600. What can I do ?

Hi,

Did you set the oscillator correctly ?

the code you provided is not working correctly here are the scren shots.
actually i ave also a problem in pic18f452 in transmitting the data using uart, but there is no issue in recieveing the data through uart .. kindly elp me also. thanks
