你问的是 ESP32-S2?但你这几行代码是 ESP32 的,S2 的应该是这样的: Code: Select all // 0~47 except from 22~25, 47 are valid #define SOC_GPIO_VALID_GPIO_MASK (0xFFFFFFFFFFFFULL & ~(0ULL | BIT22 | BIT23 | BIT24 | BIT25 | BIT47)) // GPIO 46, 47 are input only #define...
I'm developing a board using ESP32-Wrover-E in which it is running out of available GPIOs. So, I was wondering if I could use its GPIO 34 (input only) as a RX for the TX of the GPS module (L76L-M33). Is that possible? Should I use a pull-up resistor? photo_2024-08-12_...
现在，当您的ESP32 WROVER启动时，它将自动配置GPIO34、35和39为数字输入，并启用上拉电阻。同时，串口...

ESP32S3学习笔记(1)—— GPIO输出 前言 (1) (2)本章节主要是学习ESP32的GPIO输出实验。 (3)教程仓库: 实验代码 CMakeLists.txt (1)在工程目录下打开CMakeLists.txt,修改为如下内容。 # 指定CMake最小版本 cmake_minimum_required(VERSION 3.16)
Tested it for all GPIOs that can be a DI. Works for all of them but not for GPIO34 ... GPIO39. They work as input but get not pulled up. Same with INPUT_PULLDOWN. These input-only pins don't have PU/PD circuits. OK, thanks for the information. ...
ESP32的GPIO(通用输入输出)可以用于多种功能,包括数字输入/输出、PWM信号生成等。对于舵机控制,我们主要使用GPIO来生成PWM信号。 研究9g舵机的工作原理和信号要求: 9g舵机是一种小型舵机,通常通过PWM信号来控制其转动角度。标准的PWM信号频率通常为50Hz,占空比决定了舵机的转动角度。 编写ESP32 IDF代码以生成舵机控制...
