UART communication between two PSoC

[Anonymous]

Hi all,

I was trying to for UART communication between two PSoCs.

The first PSoC keeps sending 5bytes of data at every 10ms. The first bytes is constant say 0x08 and rest 4 byte is a float value.

And the second PSoC is recieving.

Both UART were configured at 57600baud rate.

The second PSoC receives everything in correct order, when it is programmed. But after a power cycle, it receives 5 bytes but sometimes not in the correct order.

eg.

if you are sending 200 as float. 200 --> 0x42c80000

first psoc is sending 08 00 00 c8 42.

But SOMETIMES after power cycle, second might receive  c8 42 08 00 00. but sometimes in the rights order.

CY_ISR(uart_rx)
{
    uint8 Index = 0;
    float value;
    if (UART_GetRxBufferSize() == 5)
        {
            for(Index = 0; Index < UART_RX_BUFFER_SIZE; Index++)
                COM_UART_Rx_Buffer[Index]= UART_GetChar(); 
            if (COM_UART_Rx_Buffer[0] == 0x08 )
                {
                    memcpy(&value,&COM_UART_Rx_Buffer[1],4);   
                }
             UART_ClearRxBuffer();  
        }       
}

The Rx buffer of second PSoC is 5.

I dont know how can i synchronise the two PSoCs.

Thanks in advance
