Hello, I am using a FT232BL in order to connect a PIC18F2450 to a USB-PORT. The FTDI is using a 48MHZ and my serial port hat 9600 bis/s so I am using the baudrate 51. In order to test the FTDI-Device I am trying to send a string to a terminal (Hterm or Tera Term) but I just receive blanks "\n" :( Could you please help me to find the mistake in my code, thank you!!! #include <stdio.h> #include <usart.h> #include "p18f2450.h" #pragma config FCMEN = ON //Fail-Safe Clock Monitor enabled #pragma config IESO = OFF //Oscillator Switchover mode disabled #pragma config PWRT = OFF //Power-up Timer disabled #pragma config MCLRE = ON //MCLR pin enabled, RE3 input pin disabled #pragma config LPT1OSC = OFF //Disabled, T1 operates in standard power mode #pragma config PBADEN = OFF //PORTB<4:0> pins are configured as digital I/O on Reset #pragma config STVREN = ON //Stack full/underflow will cause Reset #pragma config LVP = OFF //Single-Supply ICSP disabled #pragma config WDT = OFF // NO WATCH DOG TIMER #define BAUD_RATE_GEN 51 void main (void){ unsigned char Txdata[]= "HELLO"; OpenUSART(USART_TX_INT_ON & USART_RX_INT_ON & USART_ASYNCH_MODE & USART_EIGHT_BIT & USART_CONT_RX & USART_BRGH_LOW, BAUD_RATE_GEN); while(1){ putsUSART((char *)Txdata); }//End while CloseUSART(); }//End void Best regards --------------------------------------- Posted through http://www.EmbeddedRelated.com
