在Arduino编程中,将String类型转换为int类型是一个常见的需求。Arduino提供了内置的函数toInt()来实现这一转换。以下是关于如何在Arduino中将String转换为int的详细步骤和示例代码: 1. 确认Arduino编程环境已正确安装并配置 在开始编程之前,请确保你的Arduino IDE已经正确安装并配置好。这包括安装Arduino IDE软件、连接Ar...
StringIndexOf - 寻找在字符串里字符的第一个或最后一个的状态 StringLength - 获得和修剪字符串的长度 StringLengthTrim - 获得和修剪字符串的长度 StringReplace - 替换字符串里的个别字符 StringStartsWithEndsWith - 检查一个给定的字符或子串(substrings)的开始或结尾 StringSubstring - 在给定的字符串里寻找"p...
