添加 Ti Botton Driver

环境

1. 系统：Windows 10
2. SDK：simplelink_cc13x2_26x2_sdk_4_20_01_04
3. IDE：Code Composer Studio, Version: 10.0.0.00010
4. 代码工程：simple_peripheral_oad_offchip_CC26X2R1_LAUNCHXL_tirtos_ccs (已删除不必要的代码，请看：删除simple_peripheral_oad_offchip工程多余的代码)

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(&params);
    params.longPressDuration = 5000;

    Button_open(CONFIG_BUTTON_LEFT, hal_button_left_cb, &params);

    Button_open(CONFIG_BUTTON_RIGHT, hal_button_right_cb, &params);

    Button_open(CONFIG_BUTTON_BACK, hal_button_back_cb, &params);

    Button_open(CONFIG_BUTTON_ENTER, hal_button_enter_cb, &params);
}

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)
    {

    }
