dsPIC30F6015, ede1144.

[acampos1]

I am trying to display on the LCD screen the key of the keypad. For that to happen I am using a keypad encoder(ede 1144). I have the keypad encoder connected to 9600. Every time I enter a key, what is display is 255, instead of the actual key I pressed. I am not really familiar with the UART, so could anybody take a look at my code. Thanks


void initUART()
{
U2MODEbits.UARTEN = 1;
U2MODEbits.PDSEL0 = 0;
U2MODEbits.PDSEL1 = 0;
U2MODEbits.STSEL = 0;
U2STA = 1;
IFS1bits.U2RXIF = 0;
IEC1bits.U2RXIE = 1;

U2BRG = 0X00C7;

}
void __attribute__((__interrupt__)) _U2RXInterrupt(void)
{
char buff[50];
sprintf(buff, "%i", U2RXREG);
Send_String(buff);

IEC1bits.U2RXIE = 0;
U2MODEbits.UARTEN = 0;
//RTFbits.RF5 = 1;
IFS1bits.U2RXIF = 0;
IEC1bits.U2RXIE = 1;
U2MODEbits.UARTEN = 1;
}
