Hi,
I have a "frame" of about 52 bytes that I am sending into the USART Rx pin. I would like to read this in and load the data into an array that I could later grab from. Using USARTC0.DATA, how would I load the "frame" into an array this size?

char frame[52];
for (i = 0; i < 52; i++) {
while (~USARTC0.STATUS & USART_RXCIF_bm);
frame[i] = USARTC0.DATA;
}
You can also do this using a FIFO buffer that is found in ASF.
ISR(USARTC0_RXC_vect){
switch(fifo_push_uint8_t(&fifo_rx_buffer, USARTC0.DATA)){
case FIFO_OK:
//Do something or not
break;
case FIFO_ERROR_OVERFLOW:
//Do something or not
break;
}
}
