Startup code called from the reset vector determines the boot mode by checking GPIO_STRAP_REGregisterforbootstrap pin states. Depending on the reset reason, the following takes place: Reset from deep sleep:ifthe value in RTC_CNTL_STORE6_REG is non-zero, and CRC value of RTC memory in RTC...
pinMode(22,INPUT_PULLUP); pinMode(23,OUTPUT); digitalWrite(23,HIGH); Analog Input Pins Note that only a subset of ADC pins and functions are exposed. First, the supplied drivers expose only ADC1. The board layout of the ESP32-DevKitC only exposes some of the pins. Specifically, the f...
注意设计手册对WROOM封装的最小电路要求 带有SPIRAM时IO35/IO36/IO37不可使用; 部分支持ADC功能的GPIO在持续WIFI联网的情况下无法使用(下图黄色部分); 串口自动烧录电路接入GPIO0-BOOT和GPIO2-EN引脚,使用2个三极管实现 SPI设计应避开SPI0/SPI1,同时应尽量使用SPI默认引脚 其他电路不再赘述,均为基本的电源、烧录...
