Pin configuration problem of Keyfob and USB dongle

I changed hal_key.c .h and hal_led.c .h, and hal_board_cfg.h, seems led is working well, but the switch is not working, what else file I have to take care of?

Hi Xiaochuan,

glad to know you are having progress but please try to keep your questions in a single thread. Please remove and / or verify one of them. tomorrow if you have doubts I'll try to do keyfob program tests in my work place ;)

Hi kazola,

I verify theother one problem, still I could not make the dongle work. the following is the keyfob side hal_key.h original defination, I think I might have problem in this part, could you tell me how to change this part? the original port is SW1 P0_0 and SW2 P0_1, I want to change it to SW1 P1_2 and SW2 P1_3.

/* SW_1 is at P0.0 */
#define HAL_KEY_SW_1_PORT   P0
#define HAL_KEY_SW_1_BIT    BV(0)
#define HAL_KEY_SW_1_SEL    P0SEL
#define HAL_KEY_SW_1_DIR    P0DIR

/* SW_2 is at P0.1 */
#define HAL_KEY_SW_2_PORT   P0
#define HAL_KEY_SW_2_BIT    BV(1)
#define HAL_KEY_SW_2_SEL    P0SEL
#define HAL_KEY_SW_2_DIR    P0DIR

#define HAL_KEY_SW_1_IEN      IEN1  /* CPU interrupt mask register */
#define HAL_KEY_SW_1_ICTL     P0IEN /* Port Interrupt Control register */
#define HAL_KEY_SW_1_ICTLBIT  BV(0) /* P0IEN - P0.0 enable/disable bit */
#define HAL_KEY_SW_1_IENBIT   BV(5) /* Mask bit for all of Port_0 */
#define HAL_KEY_SW_1_PXIFG    P0IFG /* Interrupt flag at source */
#define HAL_KEY_SW_2_IEN      IEN1  /* CPU interrupt mask register */
#define HAL_KEY_SW_2_ICTL     P0IEN /* Port Interrupt Control register */
#define HAL_KEY_SW_2_ICTLBIT  BV(1) /* P0IEN - P0.1 enable/disable bit */
#define HAL_KEY_SW_2_IENBIT   BV(5) /* Mask bit for all of Port_0 */
#define HAL_KEY_SW_2_PXIFG    P0IFG /* Interrupt flag at source */

#define HAL_KEY_SW_1_EDGEBIT  BV(0)

Ein?

You can't! The buttons of the keyfob are soldered to the indicated input pins.

I mean change the configuration of software, make the software work.

Hi Xiaochuan,

That would be something like this;

/* SW_1 is at P1.2 */
#define HAL_KEY_SW_1_PORT P1
#define HAL_KEY_SW_1_BIT BV(2)
#define HAL_KEY_SW_1_SEL P1SEL
#define HAL_KEY_SW_1_DIR P1DIR

/* SW_2 is at P1.3 */
#define HAL_KEY_SW_2_PORT P1
#define HAL_KEY_SW_2_BIT  BV(3)
#define HAL_KEY_SW_2_SEL P1SEL
#define HAL_KEY_SW_2_DIR  P1DIR

#define HAL_KEY_SW_1_IEN IEN1 /* CPU interrupt mask register */
#define HAL_KEY_SW_1_ICTL P1IEN /* Port Interrupt Control register */ 
#define HAL_KEY_SW_1_ICTLBIT BV(2) /* P1IEN - P1.2 enable/disable bit */ 
#define HAL_KEY_SW_1_IENBIT BV(4) /* Mask bit for all of Port_1 */ 
#define HAL_KEY_SW_1_PXIFG  P1IFG /* Interrupt flag at source */
#define HAL_KEY_SW_2_IEN IEN1 /* CPU interrupt mask register */
#define HAL_KEY_SW_2_ICTL P1IEN /* Port Interrupt Control register */
#define HAL_KEY_SW_2_ICTLBIT BV(3) /* P1IEN - P1.3 enable/disable bit */
#define HAL_KEY_SW_2_IENBIT BV(4) /* Mask bit for all of Port_0 */
#define HAL_KEY_SW_2_PXIFG  P1IFG /* Interrupt flag at source */

#define HAL_KEY_SW_1_EDGEBIT BV(0)

For more details, please have a look in the CC2540 User Guide found here, especially the "2.5 Interrupts" and the "7. I/O Ports" Chapters.

Hi Nick, Thank you for your answer, but still the switch is not working, could you tell me which related files I have to change to modify the pin configuration?
