AVR microcontroller---serial port sending-EEWORLD

the first method:

void send1_1byte(float k)

{

while(UCSR1A.5==0){;}

UDR1=k;

while(UCSR1A.6==0){;}

UCSR1A.6=1;

}

void send0_1byte(float k)

{

while(UCSR0A.5==0){;}

UDR0=k;

while(UCSR0A.6==0){;}

UCSR0A.6=1;

}

This method is commonly used.

The second method:

putters (k);
