I am trying to enable simple Uart communication with my computer.
I am using atmega32 microcontroller and inbuilt Terminal in Atmel Studio 7
This is my code:
#ifndef F_CPU
#define F_CPU 1000000ul
#endif
#include <avr/io.h>
#include <util/delay.h>
#include <stdlib.h>
#include <stdio.h>
void init()
{
UCSRB |= (1<<TXEN) | (1<<RXEN);
UCSRC |= (1<<URSEL) | (1<<UCSZ0) | (1<<UCSZ1);
UBRRL = 6
UBRRH = (6 >> 8);
}
void USART_Transmit(unsigned char data)
{
while(!(UCSRA & (1<<UDRE)));
UDR = data;
}
unsigned char USART_Receive(void)
{
while((UCSRA & (1<<RXC)) == 0);
return UDR;
}
int main(void)
{
unsigned char c;
init();
while (1)
{
c = USART_Receive();
USART_Transmit(c);
}
}
The problem is when I try to send the character I'm getting back garbage value like this (¥§¶ß··öŸ)
Can you help me please!
