MSP430F1611: MSP430F1611 SPI problem

Hi Rizwan,

please understand that we can't provide example code for complete applications. In your case you have three components.

1. I2C communication

2. Push button event

3. LED on or blinking

For LED blink please see this examples in the code examples: fet140_1.c

We don't have an example for the push button event for the MSP430F1611, but you can use one of the MSP430G2553. The only difference is, that the MSP430G2553 has an internal pull up and the MSP430F1611 has not. You need to place one external. The pull up is necessary to have a defined signal and to not leave the pin floating.

#include <msp430.h>

int main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                 // Stop watchdog timer
  P1DIR = 0x01;                             // P1.0 output, else input
  P1OUT =  0x10;                            // P1.4 set, else reset
// The MSP430F1611 has no internal pull-ups 

// P1REN |= 0x10;                            // P1.4 pullup  
  P1IE |= 0x10;                             // P1.4 interrupt enabled
  P1IES |= 0x10;                            // P1.4 Hi/lo edge
  P1IFG &= ~0x10;                           // P1.4 IFG cleared

  __bis_SR_register(LPM4_bits + GIE);       // Enter LPM4 w/interrupt
}

// Port 1 interrupt service routine
#if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)

{
  P1OUT ^= 0x01;                            // P1.0 = toggle
  P1IFG &= ~0x10;                           // P1.4 IFG cleared
}
