Ja vielen Herzlichen Dank für diese tollen Informationen

Es läuft!

Hier mal nen Beispiel falls jemand das gleiche Prob hat.

C Code:

int index=0;
    char ch[19];
c = uart_getc();
        if ( c & UART_NO_DATA )
        {
            /* 
             * no data available from UART 
             */
        }
        else
        {
            /*
             * new data available from UART
             * check for Frame or Overrun error
             */
            if ( c & UART_FRAME_ERROR )
            {
                /* Framing Error detected, i.e no stop bit detected */
                uart_puts_P("UART Frame Error: ");
            }
            if ( c & UART_OVERRUN_ERROR )
            {
                /* 
                 * Overrun, a character already present in the UART UDR register was 
                 * not read by the interrupt handler before the next character arrived,
                 * one or more received characters have been dropped
                 */
                uart_puts_P("UART Overrun Error: ");
            }
            if ( c & UART_BUFFER_OVERFLOW )
            {
                /* 
                 * We are not reading the receive buffer fast enough,
                 * one or more received character have been dropped 
                 */
                uart_puts_P("Buffer overflow error: ");
            }
            /* 
             * send received character back
            */ 
           uart_putc( (unsigned char)c );
           
           if((unsigned char)c!=13)
           {
                ch[index]=c;
                index++;   
           }            
            else
            {
                ch[index]=0;
                index = 0;
                if (strcmp (ch,"TEMP1")==0)
                {
                    // Temperatur soll angefragt werden
                    uart_puts("Temperatur1=..........\n");
                }
                if (strcmp (ch,"TEMP2")==0)
                {

                    uart_puts("Temperatur2=..........\n");
                }
                if (strcmp (ch,"PH")==0)
                {
                    // Temperatur soll angefragt werden
                    uart_puts("PH=..........\n");
                }
                if (strcmp (ch,"HUMIDITY")==0)
                {
                    // Temperatur soll angefragt werden
                    uart_puts("Humidityr=..........\n");
                }
                ch[0]=0;
