大家好、

我´m 定制板来实现两个开关按钮、S1 (P0.4)和 S2 (P0.1)、我将 S1 (SW6)复制到 S2来实现它。我在 HAL_ISR_function (halKeyPort0Isr、P0INT_vector)和特殊寄存器(使用 IAR Registers 面板)中看到，当我按下 S1和 S2时，与每个代码相关的代码在一定程度上会在代码中工作(点击)。

我使用断点观察到、在两个按钮的 HalKeyPoll 中、已达到 HAL_PUSH_Button1 ()和 HAL_PUSH_Button2 ()行。它导致键值0x20 (正确值)和0x60 (0x20 + 0x040)。在这两个按钮在应用程序中引起相同的效果后、行将同时到达键和 HAL_KEY_SW_6以及键和 HAL_KEY_SW_7。

我不知道如何解决它。有人、请帮我吗？

´ll：我使用 Z-Stack Home 1.2.2a.44539、在实施后、我将升级到 Z-Stack 3.0.1。

下面的 I 包括所有与 S1和 S2相关的配置(hal_board_cfg.h、 hal_key.c、 hal_key.h 和 board.c)

hal_board_cfg.h

/* S1 */
#define PUSH1_BV          BV(4)

/* S2 */
#define PUSH2_BV          BV(1)
#define PUSH2_SBIT        P0_1

#define PUSH1_POLARITY    ACTIVE_HIGH
#define PUSH2_POLARITY    ACTIVE_HIGH

hal_key.h

/* Interrupt option - Enable or disable */
#define HAL_KEY_INTERRUPT_DISABLE    0x00
#define HAL_KEY_INTERRUPT_ENABLE     0x01

/* Key state - shift or nornal */
#define HAL_KEY_STATE_NORMAL          0x00
#define HAL_KEY_STATE_SHIFT           0x01

#define HAL_KEY_SW_1 0x01  // Joystick up
#define HAL_KEY_SW_2 0x02  // Joystick right
#define HAL_KEY_SW_5 0x04  // Joystick center
#define HAL_KEY_SW_4 0x10  // Joystick left
#define HAL_KEY_SW_3 0x08  // Joystick down ant 10
