ESP32

STM32价格一路上涨，是时候来一起支持国产了！

而且ESP32它真的很香，硬件配置及其感人啊。

ESP8266做物联网的同学应该都听过、用过，来对比下：

NodeMCU-32S

我们来看安信可做的ESP32开发板——NodeMCU-32S

直接搞起来！

这是安信可资料链接：

https://docs.ai-thinker.com/esp32/boards/nodemcu_32s

 进去之后会发现其实最主要还是要看乐鑫官方github仓库：

GitHub - espressif/arduino-esp32: Arduino core for the ESP32

接着GitHub又会提示你，到乐鑫官网看文档：

Welcome to ESP32 Arduino Core’s documentation — Arduino-ESP32 2.0.0 documentation

 

你要的东西，就全部在这个地方了。

一定要收藏！

安装

Installing — Arduino-ESP32 2.0.0 documentation


最简单的安装方式，就是在arduino软件里面，用开发板管理器进行安装。

 如果出现“下载xxxx时出错”，那就还是要翻墙，因为github没有翻墙是很难访问的。

 

上传程序

安装完成之后，关闭再打开arduino软件，就可以看到上图这些个ESP32开发板，我们找到NodeMCU-32S，并且选中端口号——COM15。

 然后打开例程——GetChipID

 点击“上传”

 经过下面这番思想斗争之后，它就上传成功了！

打开串口监视器，就可以看到Chip ID是12599576

 主要代码是这样的：

void loop() 
	for(int i=0; i<17; i=i+8) 
	  chipId |= ((ESP.getEfuseMac() >> (40 - i)) & 0xff) << i;
	

	Serial.printf("ESP32 Chip model = %s Rev %d\\n", ESP.getChipModel(), ESP.getChipRevision());
	Serial.printf("This chip has %d cores\\n", ESP.getChipCores());
  Serial.print("Chip ID: "); Serial.println(chipId);
  
	delay(3000);

就这么简单的，跑起来了。
