Re: ESP32 not working with external 5V source Postbyusername»Fri Apr 19, 2024 5:17 pm When you power it from the batteries do you get 3.3v on the 3.3v pin? Is EN and GPIO0 pins high ? did you try pressing the
配置GPIO引脚的输入/输出模式:通过gpio_config()函数配置,该函数在头文件driver/gpio.h中定义。 配置GPIO引脚电平触发和中断类型:通过gpio_set_intr_type()函数配置,可选择下降沿触发、上升沿触发、双边沿触发或者禁用中断。该函数在头文件driver/gpio.h中定义。 配置GPIO引脚的下拉/上拉电阻:通过gpio_set_pull_mod...

一、首先配置并安装好platformio 可以参考我这篇帖子:如何安装 PlatformIO? 二、下载并安装对应的库文件 1.在PIOHOME的HOME里面创建一个工程配置如下 2.在PIOHOME的libraries里面搜索并安装这两个库到你的工程中 lv_arduino lv_arduino 添加lv_arduino到工程目录下 ...
“Upper layer” main development board contains ESP32-PICO-D4 SiP, battery connector & charger circuit with LiPo charge status LEDs, Reset & pull-up IO0 buttons, and a green LED on GPIO4. “Lower layer” board has the USB connector and functions as a USB to UART bridge. Size: 17 mm...

You can use that table as a reference, or take a look at the following pinout to locate the different RTC_GPIO pins. The RTC_GPIO pins are highlighted with an orange rectangular box. You might also like reading:ESP32 Pinout Reference: Which GPIO pins should you use?
