HMI35CTP Uart problem.

[San]

hi all,
Im stuck with simple UART receive processes with HMI35CTP.
Please have a look on my code.

void sendInqury()
{

unsigned char *msg1 ,*msg2;
unsigned char receive1[4];
int i = 0;

myUARTWriteCommand1(0x81, 0x09, 0x04, 0x35, 0xFF, 0,0,0,0,0); //UART1_write command

while(1)
{
while ((UART1_Data_Ready() ) && i<4)
{
receive = UART1_Read();
i++;
}
if(i == 4)
{
break;
}
}

Im sending 5 bytes to a Device & device response with 4 bytes. (see the attached pics)

Im trying to read receive bytes individually to an array. tried several methods but no luck.

I tried to use interrupts as well.(Not sure how to use UART RX interrupts) Some of the registers in FT900 nothing changing when I write into it.

example
UART1_FCRbits.FIFO_EN=0; or UART1_FCR=0x00 doesn't change anything on UART FCR FIFO register. ( Just tried to disable FIFO)

Any help welcome

Thanks
