LPC 1227 UART 1 receiving delay

arunkollam · Jul 9, 2013

Hi,

Any have an idea about receiving strings without waiting more than 3 ms.

Code C - [expand]
1
2
3
4
5
6
7
8
9
10
11
int UART1_getchar (void)
 
    {
 
if (!(LPC_UART1->LSR & 0x01))
    {
    
    }
 
return (LPC_UART1->RBR);
    }

i tried to remove the loop, but it making errors in receiving the second and third data.so i need a proper counder or timer to me executed after sending the data.

Thanks
Arun

Hi
Iam working on a project based on uart communication on LPC 1227.The problem is that when ever i send a data through uart0 , my program is expected to receive a acknowledgement via uart1.so when ever the received data is missing or received in error, my program hangs and wait for the data which never come.So i need a function to identify the absence of string to avoid this hanging.

Thanks
Arun
