1. /**
   
2. *  \brief Modifies the contents of the PIO data output register. PIO pins must be set to
   
3. *  outputs via PioSetDir32() before they can be driven high or low through this
   
4. *  trap. This trap also sets pull direction for PIOs used as inputs.
   
5. *   
   
6. *   Note that all PIOs must be mapped in before they can be used.
   
7. *   See the PioSetMapPins32() documentation for information on valid PIO
   
8. *  directions
   
9. *   and PIO mapping.  
   
10. *   BlueCore has internal resistors which can be configured to either pull-up or
    
11. *   pull-down the pins used for input. This is controlled by the value
    
12. *   written to the output register using PioSet32().
    
13. *   The resistors pull-down if the value is zero, and pull-up otherwise, so the
    
14. *   following fragment sets pins 1 and 2 to inputs with pin 1 configured to
    
15. *   pull-up and pin 2 configured to pull-down.
    
16. *   \code
    
17. *   PioSet32(2|4, 2);
    
18. *   PioSetDir32(2|4, 0);
    
19. *   \endcode
    
20. *  \param mask Each bit in the mask corresponds to a PIO line. Bits set to 1 in this mask will
    
21. *  be modified. Bits set to 0 in this mask will not be modified.
    
22. *  \param bits Each bit in the "bits" value corresponds to a PIO line. Bits set to 1 in this
    
23. *  value will result in that PIO line being driven high. Bits set to 0 in this
    
24. *  value will result in that PIO line being driven low.
    
25. *  \return A 32 bit mask. If any bit in this mask is high then that PIO could not be
    
26. *  driven to the level specified; note that no action will have been taken on any
    
27. *  PIOs.
    
28. *
    
29. * \note This trap may NOT be called from a high-priority task handler
    
30. *
    
31. * \ingroup trapset_core

int pio_mask = (1

谢谢，可以是可以了，但是我发现我用在main.c时候，要先把下面那个portability.h的define那一堆，再main里面又定义一次。才能用你给的函数。想要include这个h文件，又会出错。请教是不是哪里用错了？

adk是6.3 好多跟4.几不一样了， 反而不会用了

你好，我也找到了这里，但是都是注释掉的，你的adk是多少?

ADK6.4~~

我的6.4，你6.3的也应该可以直接用这几个接口的，在pio.h里包含的有。

你好，你的这一段代码是在pio.h里面的，但是是灰色注释掉了的，前面有一个#if TRAPSET_CORE，应该如何使用？谢谢

sink项目里面默认是有定义TRAPSET_CORE的
