1. 添加Button 插件
添加4个Button, 并配置好IO。
2. 添加相关代码
初始化代码：
void hal_button_init(void)
{
Button_Params params;
Button_Params_init(¶ms);
params.longPressDuration = 5000;
Button_open(CONFIG_BUTTON_LEFT, hal_button_left_cb, ¶ms);
Button_open(CONFIG_BUTTON_RIGHT, hal_button_right_cb, ¶ms);
Button_open(CONFIG_BUTTON_BACK, hal_button_back_cb, ¶ms);
Button_open(CONFIG_BUTTON_ENTER, hal_button_enter_cb, ¶ms);
}
回调函数代码：
void hal_button_left_cb(Button_Handle handle, Button_EventMask events)
{
Debug("button_left: 0x%02x", events);
/*! Button pressed down, may or may not subsequently have been released */
if (events & Button_EV_PRESSED)
{
hal_buzzer_start(50, 50, 1);
}
/*! Button held down for more than tLongpress (ms) */
if (events & Button_EV_LONGPRESSED)
{
}
/*! Button released after press or longpress */
