硬件概览

它是如何工作的？

BATT-MAN 2 Click基于MAX77654，这是一款针对低功耗应用的高集成电池充电和电源管理解决方案，来自Analog Devices。它采用单电感、多输出(SIMO)升降压稳压器，能够高效地提供三个独立可编程电源轨，这些电源轨在板载端子上标记为VSB0、VSB1和VSB2。此外，它还有一个100mA的LDO输出，标记为VLDO，具有音频和其他对噪声敏感应用的纹波抑制功能。该LDO输出还可以配置为负载开关，通过在不需要时断开外部模块来管理功耗。通过填充JP2板载跳线可以激活/停用LDO输出。MAX77654还具有集成的高度可配置线性充电器，支持范围广泛的Li+电池容量，具有多种充电电流和充电终止电压选项，具备电池温度监测以增加安全性（JEITA）。当CHG电源无效（电源范围为4.1V至7.25V）、禁用或电池电量不足时，充

电器功能将关闭。除了板上的所有输出端子外，还有一个标记为VSYS的系统电源输出端子。除了为系统资源和设备的控制逻辑提供电源外，VSYS还设计用于外部使用。BATT-MAN 2 Click使用标准I2C 2线接口与MCU通信，以配置和检查设备状态。由于传感器的运行需要1.8V逻辑电压电平才能正常工作，因此使用了一个小型调节LDO，即Analog Devices的ADP160，从mikroBUS™导轨提供1.8V输出。因此，还配备了电压电平转换器。I2C接口总线线路被引到双向电压电平转换器，使此Click板™能够与3.3V和5V的MCU正常工作。板载开关标记为ENABLE，主要用于生成唤醒信号，通过将开关设置为适当位置1或0来打开稳压器。此外，此Click板™还具有一些额外功能，例如，复位引脚连接到mikroBUS™插座上的RST引脚，在

设备断电时将处理器保持在复位状态。它还使用中断引脚，即mikroBUS™插座的INT引脚，以指示设备状态的重要变化，而三个额外的LED指示灯，红色、黄色和蓝色LED，标记为LED2、LED3和LED4，可以用于可选的用户配置视觉指示。此外，该设备包括一个模拟多路复用器(AMX)，连接到mikroBUS™插座上的AN引脚，切换多个内部电压和电流信号到外部节点，以便通过外部ADC进行监测。此Click板™可通过VCC SEL跳线选择使用3.3V或5V逻辑电压水平，这样，既3.3V又5V的MCU都可以正确使用通信线路。此外，此Click板™配备了包含易于使用的功能和示例代码的库，可用作进一步开发的参考。

 * @file main.c
 * @brief BATTMAN2 Click example
 *
 * # Description
 * This library contains API for BATT-MAN 2 Click driver.
 * The library initializes and defines the I2C bus drivers 
 * to write and read data from registers. 
 * The library also includes a function for configuring appropriate charge current, 
 * charge voltage, prequalification voltage, 
 * Buck, Buck-Boost and Linear regulator configuration, etc.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of the I2C module, log UART, and additional pins. 
 * After the driver inits and executes a default configuration, 
 * the app disables charging, sets charger configuration, 
 * enables charging, displays charger configuration, 
 * or sets Buck-Boost configuration.
 *
 * ## Application Task
 * This is an example that shows the use of a BATT-MAN 2 Click board™.
 * The choice of example profile tasks depends on uncommented code.
 * Examples profile: CHARGER and BUCK-BOOST.
 * In the CHARGER profile, while on the BATT-MAN 2 click board™ the 
 * blue LED is the battery charging indicator, 
 * while the red LED indicates the cessation of battery charging. 
 * The yellow LED is an indicator of the BUCK-BOOST profile.
 * Results are being sent to the USART terminal where the user can track their changes. 
 * 
 * ## Additional Function
 * - static void display_charger_status ( void )
 * - static void display_sbb_status ( void )
