前言
POI 文档与示例方面对国人并不友好，往往不知道怎么使用，本系列主要用示例方式演示POI 4.1.2 API文档使用。提示：以下是本篇文章正文内容，下面案例可供参考
一、IndexedColors 所有颜色
IndexedColors 做为常用的颜色常量，下面演示了所有的颜色
二、使用步骤
1.pom.xml中引入依赖
代码如下（示例）：
<!-- https://mvnrepository.com/artifact/org.seasar.fisshplate/fisshplate -->
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>4.1.2</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-scratchpad</artifactId>
<version>4.1.2</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>4.1.2</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml-schemas</artifactId>
<version>4.1.2</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>ooxml-schemas</artifactId>
<version>1.4</version>
</dependency>
2.运行IndexedColorsExample main方法
代码如下（示例）：
package com.yuhan.excel.color;
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.*;
import java.awt.Color;
import java.io.FileOutputStream;
import java.io.IOException;
/**

在最后 excel保存在d://POIFillAndColorExample2.xlsx
总结
这里只是演示了Poi 中IndexedColors内置的所有颜色，下一篇将演示自定义RGB颜色如何使用

STM32学习过程记录11——基于STM32G431CBU6硬件SPI+DMA的高效WS2812B控制方法-程序员宅基地
文章浏览阅读2.3k次，点赞6次，收藏14次。SPI的详情简介不必赘述。假设我们通过SPI发送0xAA，我们的数据线就会变为10101010，通过修改不同的内容，即可修改SPI中0和1的持续时间。比如0xF0即为前半周期为高电平，后半周期为低电平的状态。在SPI的通信模式中，CPHA配置会影响该实验，下图展示了不同采样位置的SPI时序图[1]。CPOL = 0，CPHA = 1：CLK空闲状态 = 低电平，数据在下降沿采样，并在上升沿移出CPOL = 0，CPHA = 0：CLK空闲状态 = 低电平，数据在上升沿采样，并在下降沿移出。_stm32g431cbu6

文章浏览阅读10w+次，点赞93次，收藏352次。1、用strtok函数进行字符串分割原型： char *strtok(char *str, const char *delim);功能：分解字符串为一组字符串。参数说明：str为要分解的字符串，delim为分隔符字符串。返回值：从str开头开始的一个个被分割的串。当没有被分割的串时则返回NULL。其它：strtok函数线程不安全，可以使用strtok_r替代。示例：//借助strtok实现split#include <string.h>#include <stdio.h&_c++ 字符串分割
