I have built a mechanism for sending the letter 'O' every few seconds. After that I catch the recieved Data with fgets in MATLAB. fgets gives me a batch of lettters after some time which is not optimal because i want to see the arrival of each letter LIVE. Is there a way to do it in matlab?
Thanks.
while (1)
{
buffer[0] = 'O';
Delay(1000);
GPIO_PinOutSet(LED_PORT_E,15);
Delay(1000);
USART_Tx(USART1,buffer[0]);
GPIO_PinOutClear(LED_PORT_E,15);
Delay(1000);
}
