在处理Arduino中的`uint8_t`类型时，将其转换为`string`可以方便地进行字符串操作、比较和输出，使代码逻辑更加清晰。通过上述示例，我们可以看到如何简单地将`uint8_t`转换为`string`并进行输出。这些技术在处理Arduino通信和用户界面时非常有用。
要将String转换为uint8_t数组,我们需要遍历字符串中的每个字符,并将其转换为uint8_t类型。以下是一个示例函数,实现了这一转换: cpp #include <Arduino.h> // 函数声明 uint8_t* stringToUint8Array(const String& str, uint8_t* buffer, size_t bufferSize); void setup() { Serial.begin...
VS Code开发Arduino，但是Arduino相关的包管理、库管理、编译上传等功能都得由Arduino IDE提供，所以我们还是需要安装Arduino IDE。软件的安装这里略过，只说一下配置。 在上面两个软件安装完成后，接下来打开VS Code，在扩展中搜索Arduino，选择Microsoft出品的那个，安装该扩展：今天...

I'm using the RadioHead Packet Radio library from airspayce.com. In the example (nrf24_reliable_datagram_client & server) they let two nodes communicate with each other by sending strings back and forth. Now I want to send an int instead of a string there, and do something with this ...

Convert from uint8_t * to char * in C. I am programming in C using Atmel Studio (for those unfamiliar with this it is used to program to micro controllers such as arduino. You can not simply print, you have to send the data Serially to an application such as Terminal.) uint8_t ...
