Hi

The code written for rx data in LPC2129-uartO

U0LCR = 0x83;
U0DLL = 39; // baud rate = 9615 @ pclk = 6mhz
U0FCR = 0x07; //FIFO enable
U0LCR = 0x03; //Rx data as 8 bits, no Parity, 1 Stop bit

while(!(U0LSR & 0x01)); //executed untill U0RSR full
while(U0LSR & 0x01)
{
ch3[x] = U0RBR;
x++;
}

Transmitter sending stream of data among which only first 16 bytes of
data were stored in FIFO remaining were lost.Give me solution or
modify the above code such that FIFO can be erased when it fulls
without the loss of data stream

with thanks

The FIFO is automaticaly emptied as you read from it.

Change the code to:

U0LCR = 0x83;
U0DLL = 39; // baud rate = 9615 @ pclk = 6mhz
U0FCR = 0x07; //FIFO enable
U0LCR = 0x03; //Rx data as 8 bits, no Parity, 1 Stop bit

while (x {
while(!(U0LSR & 0x01)); //executed untill U0RSR full
while(U0LSR & 0x01)
{
ch3[x] = U0RBR;
x++;
}
}
