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
