I am working on a custom board with k10mcu mk10dx256. IM trying to implement uart program with it.I have attached the program.I am getting a garbage value on my serial terminal.
heres my program:
#include <__cross_studio_io.h>
#include "MK10DZ10.h"
main(){
char data = 'a';
int i;
unsigned long int SBR_value=0;
char data1,ch;
//pin selection
SIM_SCGC5 |= SIM_SCGC5_PORTD_MASK;
PORTD_PCR3 |= PORT_PCR_MUX(3);
PORTD_PCR2 |= PORT_PCR_MUX(3);
//uart selection
SIM_SCGC4 |= SIM_SCGC4_UART2_MASK;
UART2_C2 |= (1<<3)|(1<<2);
SBR_value = (int) ( (72*1000000)/ ( 16 * 9600) ) ;
UART2_BDH |= ( ( SBR_value >> 8 ) & 0x1F );
UART2_BDL = ( SBR_value & 0xFF );
while(1)
{
while( !(( UART2_S1 >> 7) & 0x01));
ch|= data;
UART2_D |=ch;
debug_printf("sending\n %s \n %d \n ",data,i#);}
}
i m getting interrupts but my data is not able to captured in receive program.
// MCG_C1 Reg Config
MCG_C1 &= ( MCG_C1_CLKS(0x00) | MCG_C1_FRDIV(0x00) );
MCG_C1 |= ( MCG_C1_IREFS_MASK | MCG_C1_IRCLKEN_MASK );
// MCG_C2 Reg Config
MCG_C2 = 0x00; // Disable all the functionalities
//SYSTEM_FREQUENCY
// MCG_C4 Reg Config selecting the range to 60 - 72Mhz
MCG_C4 |= (MCG_C4_SCFTRIM_MASK | MCG_C4_DMX32_MASK );
MCG_C4 |= ( 1 << ( MCG_C4_DRST_DRS_SHIFT + 1) ) ;
//---------- SIM Module
SIM_SOPT2 &= ~(SIM_SOPT2_PLLFLLSEL_MASK); // Selecting the FLL
// common for 72Mhz
SIM_CLKDIV1 |= ((SIM_CLKDIV1_OUTDIV4(0x02)) | (SIM_CLKDIV1_OUTDIV3(0x01)) | (SIM_CLKDIV1_OUTDIV2(0x01)) | (SIM_CLKDIV1_OUTDIV1(0x00) ) );
this is my clock configuration
for 72mhz.
this is my output after configuring the clock.
