So as the title states, instead of sending a byte of information at a time, I would like to be able to send a whole string. What I tried to do was that I tried to put the user input in an array and get each element of that array to be transmitted. However I was only able to get the first few letters to transmit not the whole array, here is my code:
//tx serial
#include <avr/io.h>
#define F_CPU 16000000
#define BUAD 9600
#define BUAD_RATE_CALC ((F_CPU/16/BUAD) - 1)
int main(void){
char ar[]= "hello";
//High and low bits
UBRR0H = (BUAD_RATE_CALC >> 8);
UBRR0L = BUAD_RATE_CALC;
////////////////
//transimit and recieve enable
UCSR0B = (1 << TXEN0)| (1 << TXCIE0) | (1 << RXEN0) | (1 << RXCIE0);
UCSR0C = (1 << UCSZ01) | (1 << UCSZ00); //8 bit data format
////////////////////////////////////////////////////////////////
int i = 0;
while (1){
while (( UCSR0A & (1<<UDRE0)) == 0){};
for (i = 0; i < strlen(ar); i++){
UDR0 = ar[i];
}
}
}
What would the problem be with this?
