[ESP32 IDF+Vscode]OLED多级菜单显示(摇杆控制)
ADC介绍
ESP32集成了两个 12位SAR(逐次逼近寄存器)adc ，共支持18个测量通道。
1、两个 ADC 通道简介：
ADC1：
- 支持 8 个通道，包括：GPIO32 - GPIO39（并非按顺序）
ADC2：
- 支持 10 个通道，包括：GPIO0, GPIO2, GPIO4, GPIO12 - GPIO15, GOIO25 - GPIO27（并非按顺序）
ESP32 内置霍尔传感器，采用 ADC1 的通道0和3（GPIO36 和 GPIO39）。如果想要使用ESP32内置的霍尔传感器，请不要对这两个GPIO做任何配置！
接线方式
