Help: problem with UART of atmega 128

[boydtvt32]

hi everybody!
I used Mikro C Pro for code atmega 128,but i can't sent and received data. i used UART Library of Mikro C and Proteus 7.10 to emulation.Please help!




this my exam code:

Code: Select all

char uart_rd;
void main() {

  UART1_Init(9600);               // Initialize UART module at 9600 bps
  Delay_ms(100);                  // Wait for UART module to stabilize
  UART1_Write_Text("Init");
  UART1_Write(13);UART1_Write(10);
  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
    }
  }
}

Hi,

Do you have a real hardware on which you have tried this ?

Hi,

The UART on ATmega128 functions OK for me on the real hardware.
Are you sure that this line is functioning correctly ?
