在嵌入式裸机开发中,经常有按键的管理需求,GitHub上已经有蛮多成熟的按键驱动了,但是由于这样那样的问题,最终还是自己实现了一套。本项目地址:bobwenstudy/easy_button (github.com)。
项目开发过程中参考了如下几个项目murphyzhao/FlexibleButton: 灵活的按键处理库(Flexible Button)| 按键驱动 | 支持单击、双击、连击、长按、自动消抖 | 灵活适配中断和低功耗 | 按需实现组合按键 (github.com),0x1abin/MultiButton: Button driver for embedded system (github.com)和MaJerle/lwbtn: Lightweight button handler for embedded systems (github.com)。
其中核心的按键管理机制借鉴的是lwbtn,并在其基础上做了比较多的改动,部分事件上报行为和原本处理有些不同。
下面从几个维度来对比几个开源库的差异。
注意:分析纯属个人观点,如有异议请随时与我沟通。
easy_button | FlexibleButton | MultiButton | lwbtn | |
---|---|---|---|---|
最大支持按键数 | 无限 | 32 | 无限 | 无限 |
按键时间参数独立配置 | 支持 | 支持 | 部分支持 | 支持 |
单个按键RAM Size(Bytes) | 20(ebtn_btn_t) | 28(flex_button_t) | 44(Button) | 48(lwbtn_btn_t) |
支持组合按键 | 支持 | 不支持 | 不支持 | 不支持 |
支持静态注册(可以省Code Size) | 支持 | 不支持 | 不支持 | 支持 |
支持动态注册 | 支持 | 支持 | 支持 | 不支持 |
单击最大次数 | 无限 | 无限 | 2 | 无限 |
长按种类 | 无限 | 1 | 1 | 无限 |
批量扫描支持 | 支持 | 不支持 | 不支持 | 不支持 |
可以看出easy_button功能是最全的,并且使用的RAM Size也是最小的,这个在键盘之类有很多按键场景下非常有意义。
现有的项目基本都不支持组合按键,基本都是要求用户根据ID在应用层将多个按键作为一个ID来实现,虽然这样也能实现组合按键的功能需要。
但是这样的实现逻辑不够优雅,并且扫描按键行为的逻辑不可避免有重复的部分,增加了mips。
本项目基于bit_array_static实现了优雅的组合按键处理机制,无需重复定义按键扫描逻辑,驱动会利用已经读取到的按键状态来实现组合按键的功能逻辑。
实际项目中会遇到各种功能需求,如长按3s是功能A,长按5s是功能B,长按30s是功能C。通过keepalive_cnt
和time_keepalive_period
的设计,能够支持各种场景的长按功能需要。
如定义time_keepalive_period=1000
,那么每隔1s会上报一个KEEPALIVE(EBTN_EVT_KEEPALIVE)
事件,应用层在收到上报事件后,当keepalive_cnt==3
时,执行功能A;当keepalive_cnt==5
时,执行功能B;当keepalive_cnt==30
时,执行功能C。
现有的按键库都是一个个按键扫描再单独处理,这个在按键比较少的时候,比较好管理,但是在多按键场景下,尤其是矩阵键盘下,这个会大大增加扫描延迟,通过批量扫描支持,可以先在用户层将所有按键状态记录好(用户层根据具体应用优化获取速度),而后一次性将当前状态传给(ebtn_process_with_curr_state
)驱动。
嵌入式按键处理驱动,支持单击、双击、多击、自动消抖、长按、长长按、超长按 | 低功耗支持 | 组合按键支持 | 静态/动态注册支持
参考lwbtn实现,当有按键事件发生时,所上报的事件类型只有4种,通过click_cnt
和keepalive_cnt
来支持灵活的按键点击和长按功能需要,这样的设计大大简化了代码行为,也大大降低了后续维护成本。
如果用户觉得不好用,也可以在该驱动基础上再封装出自己所需的驱动。
typedef enum
{
EBTN_EVT_ONPRESS = 0x00, /*!< On press event - sent when valid press is detected */
EBTN_EVT_ONRELEASE, /*!< On release event - sent when valid release event is detected (from
active to inactive) */
EBTN_EVT_ONCLICK, /*!< On Click event - sent when valid sequence of on-press and on-release
events occurs */
EBTN_EVT_KEEPALIVE, /*!< Keep alive event - sent periodically when button is active */
} ebtn_evt_t;
参考Flexible Button,本按键库是通过不间断扫描的方式来检查按键状态,因此会一直占用 CPU 资源,这对低功耗应用场景是不友好的。为了降低正常工作模式下的功耗,建议合理配置扫描周期(5ms - 20ms),扫描间隙里 CPU 可以进入轻度睡眠。
一般MCU都有深度睡眠模式,这是CPU只能被IO切换唤醒,所以驱动为大家提供了int ebtn_is_in_process(void)
接口来判断是否可以进入深度睡眠模式。
代码结构如下所示:
- ebtn:驱动库,主要包含BitArray管理和EasyButton管理。
- example_user.c:捕获windows的0-9作为按键输入,测试用户交互的例程。
- example_test.c:模拟一些场景的按键事件,对驱动进行测试。
- main.c:程序主入口,配置进行测试模式函数用户交互模式。
- build.mk和Makefile:Makefile编译环境。
- README.md:说明文档

Step1:定义KEY_ID、按键参数和按键数组和组合按键数组。
typedef enum
{
USER_BUTTON_0 = 0,
USER_BUTTON_1,
USER_BUTTON_2,
USER_BUTTON_3,
USER_BUTTON_4,
USER_BUTTON_5,
USER_BUTTON_6,

USER_BUTTON_COMBO_1,
USER_BUTTON_COMBO_2,
USER_BUTTON_COMBO_3,
USER_BUTTON_COMBO_MAX,
} user_button_t;
/* User defined settings */
static const ebtn_btn_param_t defaul_ebtn_param = EBTN_PARAMS_INIT(20, 0, 20, 300, 200, 500, 10);
static ebtn_btn_t btns[] = {
EBTN_BUTTON_INIT(USER_BUTTON_0, &defaul_ebtn_param),
EBTN_BUTTON_INIT(USER_BUTTON_1, &defaul_ebtn_param),
EBTN_BUTTON_INIT(USER_BUTTON_2, &defaul_ebtn_param),
EBTN_BUTTON_INIT(USER_BUTTON_3, &defaul_ebtn_param),
EBTN_BUTTON_INIT(USER_BUTTON_4, &defaul_ebtn_param),
EBTN_BUTTON_INIT(USER_BUTTON_5, &defaul_ebtn_param),
};
static ebtn_btn_combo_t btns_combo[] = {
EBTN_BUTTON_COMBO_INIT(USER_BUTTON_COMBO_0, &defaul_ebtn_param),
EBTN_BUTTON_COMBO_INIT(USER_BUTTON_COMBO_1, &defaul_ebtn_param),
};
Step2:初始化按键驱动
ebtn_init(btns, EBTN_ARRAY_SIZE(btns), btns_combo, EBTN_ARRAY_SIZE(btns_combo),
prv_btn_get_state, prv_btn_event);
Step3:配置组合按键comb_key,必须在按键注册完毕后再配置,不然需要ebtn_combo_btn_add_btn_by_idx
用这个接口。
ebtn_combo_btn_add_btn(&btns_combo[0], USER_BUTTON_0);
ebtn_combo_btn_add_btn(&btns_combo[0], USER_BUTTON_1);
ebtn_combo_btn_add_btn(&btns_combo[1], USER_BUTTON_2);
ebtn_combo_btn_add_btn(&btns_combo[1], USER_BUTTON_3);
Step4:动态注册所需按键,并配置comb_key。
// dynamic register
for (int i = 0; i < (EBTN_ARRAY_SIZE(btns_dyn)); i++)
{
ebtn_register(&btns_dyn[i]);
}
ebtn_combo_btn_add_btn(&btns_combo_dyn[0].btn, USER_BUTTON_4);
ebtn_combo_btn_add_btn(&btns_combo_dyn[0].btn, USER_BUTTON_5);
ebtn_combo_btn_add_btn(&btns_combo_dyn[1].btn, USER_BUTTON_6);
ebtn_combo_btn_add_btn(&btns_combo_dyn[1].btn, USER_BUTTON_7);
for (int i = 0; i < (EBTN_ARRAY_SIZE(btns_combo_dyn)); i++)
{
ebtn_combo_register(&btns_combo_dyn[i]);
}
Step5:启动按键扫描,具体实现可以用定时器做,也可以启任务或者轮询处理。需要注意需要将当前系统时钟get_tick()
传给驱动接口ebtn_process
。
while (1)
{
/* Process forever */
ebtn_process(get_tick());
/* Artificial sleep to offload win process */
Sleep(5);
}
具体可以参考example_user.c
和example_test.c
的实现。
为了更好的实现组合按键以及批量扫描的支持,驱动引入了BitArray来管理按键的历史状态和组合按键信息。这样就间接引入了key_index的概念,其代表独立按键在驱动的位置,该值不可直接设置,是按照一定规则隐式定义的。
key_id是用户定义的,用于标识按键的,该值可以随意更改,但是尽量保证该值独立。
如下图所示,驱动有2个静态注册的按键,还有3个动态注册的按键。每个按键的key_id是随意定义的,但是key_idx却是驱动内部隐式定义的,先是静态数组,而后按照动态数组顺先依次定义。
注意:由于组合按键也会用到key_idx的信息,所以动态按键目前并不提供删除按键的行为,这个可能引发一些风险。
按键根据不同的时间触发不同的事件,目前每个按键可以配置的参数如下。
名称 | 说明 |
---|---|
time_debounce | 防抖处理,按下防抖超时,配置为0,代表不启动 |
time_debounce_release | 防抖处理,松开防抖超时,配置为0,代表不启动 |
time_click_pressed_min | 按键超时处理,按键最短时间,配置为0,代表不检查最小值 |
time_click_pressed_max | 按键超时处理,按键最长时间,配置为0xFFFF,代表不检查最大值,用于区分长按和按键事件。 |
time_click_multi_max | 多击处理,两个按键之间认为是连击的超时时间 |
time_keepalive_period | 长按处理,长按周期,每个周期增加keepalive_cnt计数 |
max_consecutive | 最大连击次数,配置为0,代表不进行连击检查。 |

每个组合按键有一个管理结构体,用于记录组合按键组合配置参数,以及按键信息。
名称 | 说明 |

主要的就是初始化和运行接口,加上动态注册接口。
void ebtn_process(ebtn_time_t mstime);
int ebtn_init(ebtn_btn_t *btns, uint16_t btns_cnt, ebtn_btn_combo_t *btns_combo,
uint16_t btns_combo_cnt, ebtn_get_state_fn get_state_fn, ebtn_evt_fn evt_fn);
int ebtn_register(ebtn_btn_dyn_t *button);
int ebtn_combo_register(ebtn_btn_combo_dyn_t *button);
用于给组合按键绑定btn使用,最终都是关联到key_idx
上。
注意,key_id
注册接口必需先确保对应的Button已经注册到驱动中。
void ebtn_combo_btn_add_btn_by_idx(ebtn_btn_combo_t *btn, int idx);
void ebtn_combo_btn_remove_btn_by_idx(ebtn_btn_combo_t *btn, int idx);
void ebtn_combo_btn_add_btn(ebtn_btn_combo_t *btn, uint16_t key_id);
void ebtn_combo_btn_remove_btn(ebtn_btn_combo_t *btn, uint16_t key_id);
一些工具函数,按需使用。
void ebtn_process_with_curr_state(bit_array_t *curr_state, ebtn_time_t mstime);
int ebtn_get_total_btn_cnt(void);
int ebtn_get_btn_index_by_key_id(uint16_t key_id);
ebtn_btn_t *ebtn_get_btn_by_key_id(uint16_t key_id);
int ebtn_get_btn_index_by_btn(ebtn_btn_t *btn);
int ebtn_get_btn_index_by_btn_dyn(ebtn_btn_dyn_t *btn);
int ebtn_is_btn_active(const ebtn_btn_t *btn);
int ebtn_is_btn_in_process(const ebtn_btn_t *btn);
int ebtn_is_in_process(void);
其中ebtn_is_in_process()
可以用于超低功耗业务场景,这时候MCU只有靠IO翻转唤醒。
这里参考用户手册 — LwBTN 文档 (majerle.eu)对本驱动的按键实现机制进行说明。
在驱动运行中,应用程序可以会接收到如下事件:
EBTN_EVT_ONPRESS
(简称:ONPRESS
),每当输入从非活动状态变为活动状态并且最短去抖动时间过去时,都会将事件发送到应用程序EBTN_EVT_ONRELEASE
(简称:ONRELEASE
),每当输入发送ONPRESS
事件时,以及当输入从活动状态变为非活动状态时,都会将事件发送到应用程序EBTN_EVT_KEEPALIVE
(简称:KEEPALIVE
),事件在ONPRESS
和ONRELEASE
事件之间定期发送EBTN_EVT_ONCLICK
(简称:ONCLICK
),事件在ONRELEASE
后发送,并且仅当活动按钮状态在有效单击事件的允许窗口内时发送。
ONPRESS
事件是检测到按键处于活动状态时的第一个事件。 由于嵌入式系统的性质和连接到设备的各种按钮,有必要过滤掉潜在的噪音,以忽略无意的多次按下。 这是通过检查输入至少在一些最短时间内处于稳定水平来完成的,通常称为消抖时间,通常需要大约20ms
。
按键消抖时间分为按下消抖时间time_debounce
和松开消抖时间time_debounce_release
。
当按键从活动状态变为非活动状态时,才会立即触发 ONRELEASE
事件,前提是在此之前检测到ONPRESS
事件。也就是 ONRELEASE
事件是伴随着ONPRESS
事件发生的。
ONCLICK
事件在多个事件组合后触发:
- 应正确检测到
ONPRESS
事件,表示按钮已按下 - 应检测到
ONRELEASE
事件,表示按钮已松开 ONPRESS
和ONRELEASE
事件之间的时间必须在时间窗口内,也就是在time_click_pressed_min
和time_click_pressed_max
之间时。
当满足条件时,在ONRELEASE
事件之后的time_click_multi_max
时间,发送ONCLICK
事件。
下面显示了在 Windows 测试下的单击事件演示。
实际需求除了单击需求外,还需要满足多击需求。本驱动是靠time_click_multi_max
来满足此功能,虽然有多次点击,但是只发送一次 ONCLICK
事件。
注意:想象一下,有一个按钮可以在单击时切换一盏灯,并在双击时关闭房间中的所有灯。 通过超时功能和单次点击通知,用户将只收到一次点击,并且会根据连续按压次数值,来执行适当的操作。
下面是Multi-Click的简化图,忽略了消抖时间。click_cnt
表示检测到的Multi-Click 事件数,将在最终的ONCLICK
事件中上报。
需要注意前一个按键的ONRELEASE
事件和下次的ONPRESS
事件间隔时间应小于time_click_multi_max
,ONCLICK
事件会在最后一次按键的ONRELEASE
事件之后time_click_multi_max
时间上报。
下面显示了在 Windows 测试下的三击事件演示。
KEEPALIVE
事件在 ONPRESS
事件和ONRELEASE
事件之间定期发送,它可用于长按处理,根据过程中有多少KEEPALIVE
事件以及time_keepalive_period
可以实现各种复杂的长按功能需求。
需要注意这里根据配置的时间参数的不同,可能会出现KEEPALIVE
事件和ONCLICK
事件在一次按键事件都上报的情况。这个情况一般发生在按下保持时间(ONPRESS
事件和ONRELEASE
事件之间)大于time_keepalive_period
却小于time_click_pressed_max
的场景下。
下面显示了在 Windows 测试下的KEEPALIVE
事件和ONCLICK
事件在一次按键事件出现的演示。
而当按下保持时间大于time_click_pressed_max
时,就不会上报ONCLICK
事件,如下图所示。
在example_test.c
中对一些场景进行了覆盖性测试,具体可以看代码实现,测试都符合预期。
注意:time_overflow相关的case需要EBTN_CONFIG_TIMER_16
宏,不然测试时间太长了。
目前测试暂时只支持Windows编译,最终生成exe,可以直接在PC上跑。
目前需要安装如下环境:
- GCC环境,笔者用的msys64+mingw,用于编译生成exe,参考这个文章安装即可。Win7下msys64安装mingw工具链 - Milton - 博客园 (cnblogs.com)。
本项目都是由makefile组织编译的,编译整个项目只需要执行make all
即可。
也就是可以通过如下指令来编译工程:
make all
而后运行执行make run
即可运行例程,例程默认运行测试例程,覆盖绝大多数场景,从结果上看测试通过。

Executing 'run: all' complete!
当然可以用windows的按键进行交互测试,详见example_user.c
的处理,main.c
选择调用example_user()
。
