Hi,
I have been trying to use the inbuilt IrDA decoder and encoder in msp430f5438.
but it is giving output as 255 always and for all type of commands and for all different remotes.
the ir receiver i am using is TSOP38438.
Please help me if you can.
Output:
data=> 255
data=> 255
data=> 255
data=> 255
data=> 255
data=> 255
data=> 255
data=> 255
THANKS IN ADVANCE

UCA1BR1 = 0;
UCA1MCTL = UCBRS_7 + UCBRF_0 + UCOS16;
UCA1IRTCTL = UCIRTXPL2 + UCIRTXPL0 + UCIRTXCLK + UCIREN;
UCA1IRRCTL = UCIRRXPL; // Light = low pulse
UCA1CTL1 &= ~UCSWRST; // Resume operation
UCA1IE |= UCRXIE; // Enable RX int
System_printf("out irda\n");
