它是如何工作的?

2x4 RGB Click基于来自Würth Elektronik的2x4 RGB LED阵列(WL-ICLED 1312121320437),专为动态和色彩丰富的照明应用而设计。这些LED集成了一个IC(常称为可寻址或智能LED),通过脉宽调制(PWM)实现对每个二极管的红、绿、蓝组件的单独控制,从而实现精确的颜色混合,提供广泛的色彩输出。为确保与3.3V和5V逻辑系统兼容,该Click板™配备了LSF0102电压转换器,无缝控制LED,无论MCU

的逻辑电平如何,确保在各种系统配置中的可靠性能。2x4 RGB Click采用了独特的设计,支持MIKROE新推出的“Click Snap”功能。与标准版Click板不同,此功能允许通过断开PCB使主IC区域变为可移动状态,开辟了许多新的实现可能性。得益于Snap功能,1312121320437可以通过直接访问标记为1-8的引脚自主运行。此外,Snap部分还包含指定和固定的螺钉孔位置,允许用户将Snap板固定在所需位置,并在顶

部配备未焊接的J1接头,允许串联多个Snap单元进行控制。此Click板™可以通过VCC SEL跳线选择在3.3V或5V逻辑电压下运行。这样,支持3.3V和5V逻辑电平的MCU都可以正确使用通信线路。此外,该Click板™还配备了包含易于使用的函数和示例代码的库,可作为进一步开发的参考。

应用程序输出

1. 应用程序输出 - 在调试模式下,“应用程序输出”窗口支持实时数据监控,直接提供执行结果的可视化。请按照提供的教程正确配置环境,以确保数据正确显示。

2. UART 终端 - 使用UART Terminal通过USB to UART converter监视数据传输,实现Click board™与开发系统之间的直接通信。请根据项目需求配置波特率和其他串行设置,以确保正常运行。有关分步设置说明,请参考提供的教程

3. Plot 输出 - Plot功能提供了一种强大的方式来可视化实时传感器数据,使趋势分析、调试和多个数据点的对比变得更加直观。要正确设置,请按照提供的教程,其中包含使用Plot功能显示Click board™读数的分步示例。在代码中使用Plot功能时,请使用以下函数:plot(insert_graph_name, variable_name);。这是一个通用格式,用户需要将“insert_graph_name”替换为实际图表名称,并将“variable_name”替换为要显示的参数。

/*!
 * @file main.c
 * @brief 2x4 RGB Click Example.
 *
 * # Description
 * This example demonstrates the use of 2x4 RGB click board by cycling through
 * a set of colors, gradually increasing the brightness of each LED in a sequence,
 * and then decreasing the brightness before moving on to the next color in the array.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration which sets
 * the LEDs brightness and current gain to a minimum and the color to black (all LEDs off).
 *
 * ## Application Task
 * Cycles through a set of colors, gradually increases the brightness of each LED
 * in a sequence, and then decreases the brightness before moving on to the next
 * color in the array. The current color's name and RGB value are logged to the USB UART.
