MSP430F249: MSP430F249

Hi Swarna Latha

May I know which HEX format you selected

I select TI hex

The HEX file content is different with yours

Thanks

Hi Xiaodong LI ,

The example code is build in IAR tool ( Linker settings to generate the hex file)

Then used the FET-PRO Tool with the below settings 

I also tried the LED example code, LED blinks once even though the code is in awhile loop. 

//******************************************************************************
// MSP430x2xx Demo - Software Toggle P1.0
//
// Description; Toggle P1.0 by xor'ing P1.0 inside of a software loop.
// ACLK = n/a, MCLK = SMCLK = default DCO
//
// MSP430x2xx
// -----------------
// /|\| XIN|-
// | | |
// --|RST XOUT|-
// | |
// | P1.0|-->LED

//******************************************************************************

#include "msp430.h"
volatile unsigned int i;
int main(void)
{
WDTCTL = WDTPW + WDTHOLD; // Stop WDT

P3DIR |= 0x01;  // Green LED
P6DIR |= 0x01;  //RED LED

while (1){

volatile unsigned int i; // volatile to prevent optimization

P3OUT ^= 0x01; // Toggle P1.0 using exclusive-OR

__delay_cycles(500000);
P6OUT ^= 0x01;

}

}

2. 32.768KHz  crystal is connected to XIN& XOUT of MCU MSP430F249. Without settings these the code exists ?? or why the LED blink is not happening. I see only once when I reprogram the hex image. 

Hi Swarna Latha

Could you provide the link of the LED example code?

I download and checked the example code of this device on https://www.ti.com/tool/download/SLAC149

But I haven't found this code

Thanks
