how to using PWM in zstack 1.2.2a？

Other Parts Discussed in Thread: TIMAC, Z-STACK

Hi all

i found there is some define （ HAL_PWM ） in the samplelight case！

#if (defined HAL_BOARD_ZLIGHT) || (defined HAL_PWM)
  HalTimer1Init( 0 );
  halTimer1SetChannelDuty( WHITE_LED, 0 );
  halTimer1SetChannelDuty( RED_LED, 0 );
  halTimer1SetChannelDuty( BLUE_LED, 0 );
  halTimer1SetChannelDuty( GREEN_LED, 0 );
...
#endif

but when i go to the function define halTimer1SetChannelDuty （） in hal_timer.c

there is a note ：

/*********************************************************************
 NOTE: Z-Stack and TIMAC no longer use CC2530 Timer 1, Timer 3, and 
       Timer 4. The supporting timer driver module is removed and left 
       for the users to implement their own application timer 
       functions.
*********************************************************************/

so does it mean although i have define HAL_PWM ， it doesn't work ！？？？

How could i set a PWM in application？ is there any more API function for user？

Actually, it means timer 1, 3, and 4 are free from Z-Stack/TIMAC and available for application developers. So, you can use those APIs.

1.Yes, it would work if you use those API.

2. You can find halTimer1SetChannelDuty in hal_timer.c which you can refer to the following screen shot.

I use Z-Stack Home 1.2.2a and you should find hal_timer.c under C:\Texas Instruments\Z-Stack Home 1.2.2a.44539\Components\hal\target\CC2530PMP4712

hal_timer.c in the \target\CC2530PMP4712 is different with the one in \target\CC2530EB

Thank you very much ！
