(源码)基于BlueMicroBLE框架的自定义键盘固件构建系统.zip

/* 这段代码是一个用于蓝牙键盘的固件，主要用于处理键盘扫描、按键事件、蓝牙连接、电池监控以及RGB LED和PWM LED的更新。以下是详细的代码功能解释： 1. **初始化配置**：`setupConfig`函数初始化键盘的配置，包括LED状态、连接模式、电池监控等。`loadConfig`函数加载存储在Flash中的配置信息，如果没有找到有效配置，将调用`resetConfig`函数进行重置并保存新配置。 2. **键盘扫描**：`scanMatrix`函数负责扫描键盘矩阵，检测按键的按下和释放事件，并将这些事件转换为键盘报告。 3. **按键处理**：`process_user_macros`和`process_keyboard_function`函数处理用户的宏和键盘功能键。`process_user_special_keys`函数处理特殊的按键事件。 4. **通信**：`sendKeyPresses`函数负责将键盘报告发送到连接的计算机或其他设备。`sendlayer`函数发送当前键盘层信息。 5. **电池监控**：`batterymonitor`类用于监控电池状态，包括电压、百分比和类型。 6. **RGB LED和PWM LED**：`updateRGB`和`updatePWM`函数用于更新RGB LED和PWM LED的状态。 7. **主循环**：`loop`函数是固件的主循环，负责执行各种任务，包括更新蓝牙连接状态、电池状态、RGB LED和PWM LED状态，以及发送键盘报告。 8. **空闲任务**：`vApplicationIdleHook`函数是FreeRTOS的空闲任务，用于在没有其他任务执行时降低设备的功耗。 9. **其他任务**：`keyscantimer_callback`函数是键盘扫描计时器的回调函数，负责扫描键盘和发送键盘报告。`batterytimer_callback`函数是电池计时器的回调函数，用于更新电池状态，但在这个代码中已被注释掉。`NormalPriorityloop`和`LowestPriorityloop`是优先级不同的循环，用于执行不同优先级的任务。 注意，这段代码使用了一些自定义的宏和函数，如`EXPAND_ALT_CODE`，它们可能是用来扩展特殊按键组合的。此外，代码中使用了`cppcheck-suppress`注释，用于抑制某些cppcheck的警告，这可能表明某些函数或代码段是故意被忽略的。 */ /**************************************************************************************************************************/ #include <Arduino.h> #include <bluefruit.h> #include "firmware.h" #include <Adafruit_LittleFS.h> #include <InternalFileSystem.h> /**************************************************************************************************************************/ byte rows[] MATRIX_ROW_PINS;
