MSP430FR2355: In MSP430FR2355 example code for SPO2 produces junk values always. How to get rid of it?

Part Number: MSP430FR2355

LOG_waitCommand();

PPG_appStart();

PPG_appSleep();

PPG_appStop();

while running the code the system goes to wait state

void LOG_waitCommand(void)
{
// wait for UART command
UCA1IE |= UCRXIE; // Enable USCI_A1 RX interrupt
__bis_SR_register(LPM0_bits | GIE); // Enter LPM0 w/ interrupts
__no_operation();
}

If i commentout LOG_waitCommand then the program produces its own values 

Hi Ganna,

This is LOG mode, in this mode, MCU will waiting the command from GUI, then capture the lighting data and send to GUI.

This is a debug mode, you would like to capture some data via GUI? right?

If you want to run normal function, you need change ENABLE_DATA_LOG to 0(PPG.h)

Thanks!

Best Regards

Johnson
