CC2530 Interrupt Enable a GPI pin

Hello Reza,

You should be able to find an example using interrupts in the examples folder.  If you search for GPIO_Interrupt_Init(void);  You first have to enable the interrupt:

  /* Enable interrupts */
  HAL_ENABLE_INTERRUPTS();

That function will initialize the pin you want to use for the interrupt.  Here is an example of the initialization.  Search the both the files and the User Manual to see how and why these register values are set.

  P1IFG = 0;                // clear all interrupt flags for P!
  P1DIR &= ~BV(5);  // set bit as input
  PICTL |= BV(5);       // enable interrupt on Bit
  PICTL |= BV(0);       // enable rising and falling edge interrupt
  P1IFG &= ~BV(5);   // clear interrupt flag
  P1IEN |= BV(5);      // enable P1 interrupt
  P1 = 0x10;               // All pins on port 1 to low except P1_5 (button)

Then search the files for the ISR routine and read the HAL documentation pdf on how to implement it.

HAL_ISR_FUNCTION( MyIsr, P1INT_VECTOR )

Inside the ISR routine you will clear the appropriate flags for the interrupt that has occured after your code section

///.... your code here

  /*
    Clear the CPU interrupt flag for Port_1
    PxIFG has to be cleared before PxIF
  */
  HAL_KEY_LS_PXIFG = 0;

  HAL_KEY_CPU_PORT_1_IF = 0;

This is just a guide to get you started.  You will have to read the documentation, look through the code and then search the forum for specific problems you are having.

Thanks,

Hi,

You can refer to hal_key.c in \your TI installation folder\ZStack-CC2530-2.5.1a\Components\hal\target\CC2530EB.
