(ESP8266没内部DAC,如果要播放录音需要外加MAX98357A) 注:而由于内部DAC方式声音太小,所以本实验优先考虑使用MAX98357A,对于内部DAC输出直接调用第三方库,而不直接对i2s就行配置了(主要原因是我直接配置内部DAC的i2s输出的声音很杂,肯定是哪里没配好,只能用第三方库了,等我搞懂了再更新吧) 一、使用外部DAC即MAX...

将ChatGPT与ESP32进行结合,可以在物联网应用方面做出更有意思的事情,如聊天机器人、语音助手和自然语言界面。下面,我将在ESP32中使用ChatGPT API。 为了让ESP32从ChatGPT获得响应,我们需要进行以下步骤: 1、在OpenAI网站上注册,并在ESP32上安装必要的库。
