Hello everyone. I am trying to check the output data using spi from the MSP430F5529 Launch Pad kit in Digital Oscillscope. Can anyone let me know what changes to be made in clock settings in programming and any changes to be made in Oscillscope hardware. I have initialized the clock and tried monitoring the data, but No output resulted in the Hardware. Any help would be greatly appreciated.
Thanks in Advance.
void initClockTo16MHz()
{
UCSCTL3 |= SELREF_2; // Set DCO FLL reference = REFO
UCSCTL4 |= SELA_2; // Set ACLK = REFO
__bis_SR_register(SCG0); // Disable the FLL control loop
UCSCTL0 = 0x0000; // Set lowest possible DCOx, MODx
UCSCTL1 = DCORSEL_5; // Select DCO range 16MHz operation
UCSCTL2 = FLLD_0 + 487; // Set DCO Multiplier for 16MHz
// (N + 1) * FLLRef = Fdco
// (487 + 1) * 32768 = 16MHz
// Set FLL Div = fDCOCLK
__bic_SR_register(SCG0); // Enable the FLL control loop
// Worst-case settling time for the DCO when the DCO range bits have been
// changed is n x 32 x 32 x f_MCLK / f_FLL_reference. See UCS chapter in 5xx
// UG for optimization.
// 32 x 32 x 16 MHz / 32,768 Hz = 500000 = MCLK cycles for DCO to settle
__delay_cycles(500000);//
// Loop until XT1,XT2 & DCO fault flag is cleared
do
{
UCSCTL7 &= ~(XT2OFFG + XT1LFOFFG + DCOFFG); // Clear XT2,XT1,DCO fault flags
SFRIFG1 &= ~OFIFG; // Clear fault flags
}while (SFRIFG1&OFIFG); // Test oscillator fault flag
}
