Hello forum!

I'm facing a difficulties in configuring UART[2] receive on my LPC2368 board
from futurlec.com.
I've succeeded in writing character (transmit) to UART[2] by adapting from
the sample code given,
but I'm kinda confused with the sample code given to get character from
UART[2]. Here's the sample code I'll be adapting from:

if(U2LSR & 0x01)
{
uart_data = getchar2();
if(uart_data==0x0D)
{
sprintf(uart2_buf,"ET-JR ARM7 LPC2368 : UART[2]\n\r");
print_uart2();
}
putchar2(uart_data);
}

Since I'm gonna use the character received by UART[2] to deliver the
feedback from LCD projector (such as lamp hour),
I need more than an 0x0D (enter button). I need to get like "65h43m21s" kind
of data. Here's what I've done by adapting from the code above

if(U2LSR & 0x01)
{
uart_data = getchar2();
sprintf(LCDlife,"%c",uart_data);
}

Did I miss something on my program? Thanks in advance for your help!

Hey Daniel,

If you really want to learn what you missed in your proposition, try to
understand the following dirty&simple adaptation from your code.

...
if(U2LSR & 0x01)
{
uart_data = getchar2();
if(uart_data==0x0D) //or whatever end of line your system sends
{
LCDLife[charpos] = 0; //NULL termination for the string
charpos = 0; //charpos should be static to your function

//LCDLife array is now complete
//Do what you need to do with the information collected
...
}
else
{
LCDLife[charpos] = uart_data;
charpos = charpos + 1; //update the position on the array for the next
character
}
}
...
