Hi,
I have implemented a code in msp430f5438 evm which is working but not as expected.
Well, here is the code for configuring the IrDA mode in USCI of msp430f5438.
the output of this code is
correct me where i am wrong.

this is the IR receiver i am using and it is directly connected to the USCI Uart Rx pin which is configured in Irda mode.

Code:
void irda_init(void)
{
UCA1CTL1 |= UCSWRST;
UCA1CTL0 |= 0x00;
UCA1CTL1 |= UCSSEL__SMCLK;
UCA1MCTL |= UCBRF_0 + UCBRS_7 + UCOS16;
UCA1STAT &= ~UCLISTEN;
UCA1IRTCTL |= UCIRTXPL5 + UCIRTXCLK + UCIREN ;
UCA1IRRCTL |= UCIRRXFL5 + UCIRRXPL;// + UCIRRXFE;
UCA1CTL1 &= ~UCSWRST;
UCA1IE |= UCRXIE;
}
void hwi_irda(void)
{
_DINT();
System_printf("IRDATA = %d\t %x\t %c\n",UCA1RXBUF,UCA1RXBUF,UCA1RXBUF);
System_flush();
_EINT();
}the output of this code is
Code:
in irda init
