ESP32-CAM模块Arduino环境搭建测试

一.ESP32+OV2640摄像头模块CameraWebServer视频查看

二.测试ESP32-CAM(后续称cam模块)代码是否上传执行成功测试

const int led0 = 12;
const int led1 = 13;void setup() {// put your setup code here, to run once:pinMode(led0, OUTPUT);pinMode(led1, OUTPUT);
}void loop() {// put your main code here, to run repeatedly:digitalWrite(led0, HIGH);digitalWrite(led1, HIGH);delay(5000);digitalWrite(led0, LOW);digitalWrite(led1, LOW);delay(500);
}

PS:上叙代码是测试cam模块代码是否执行成功

二.由于之前使用的是Arduino IDE 1.8.5版本,ESP32-CAM模块上传代码后报错 Camera probe failed with error 0x105(ESP_ERR_NOT_FOUND) Camera init failed with error 0x105 , 代码如下

代码片段①

#include <esp_camera.h>// 定义摄像头模块的引脚连接
#define CAMERA_MODEL_AI_THINKER // 如果你使用的是 AI Thinker 摄像头模块，请取消注释此行

}void loop() {// 拍照camera_fb_t *fb = NULL;fb = esp_camera_fb_get();if (!fb) {Serial.println("获取图像缓冲区失败");return;}// 在串口打印图像大小Serial.printf("分辨率: %dx%d, 图像大小: %u bytes\n", fb->width, fb->height, fb->len);// 闪烁 LED 表示拍照完成digitalWrite(ledPin, HIGH);delay(500);digitalWrite(ledPin, LOW);// 释放图像缓冲区esp_camera_fb_return(fb);
}

ps:上叙代码片段报错 Camera probe failed with error 0x105(ESP_ERR_NOT_FOUND) Camera init failed with error 0x105,
获取图像失败！

}

串口报错 Camera probe failed with error 0x105(ESP_ERR_NOT_FOUND) Camera init failed with error 0x105, 报错ESPAsyncWebServer.h,esp_camera.h not found , 获取图像失败！

代码片段③

#include "esp_camera.h"// 定义摄像头配置
camera_config_t config;void setup() {Serial.begin(115200);// 配置摄像头config.ledc_channel = LEDC_CHANNEL_0;config.ledc_timer = LEDC_TIMER_0;config.pin_d0 = 32;config.pin_d1 = 35;config.pin_d2 = 34;config.pin_d3 = 5;config.pin_d4 = 39;config.pin_d5 = 18;config.pin_d6 = 36;config.pin_d7 = 19;config.pin_xclk = 27;config.pin_pclk = 21;config.pin_vsync = 25;config.pin_href = 26;config.pin_sscb_sda = 22;config.pin_sscb_scl = 23;config.pin_reset = -1; // 不使用复位引脚config.xclk_freq_hz = 20000000;config.pixel_format = PIXFORMAT_JPEG;// 启动摄像头esp_err_t err = esp_camera_init(&config);if (err != ESP_OK) {Serial.printf("摄像头启动失败！错误代码: 0x%x\n", err);return;}Serial.println("摄像头已启动！");

}

上叙代码还是同样报错,导致一度怀疑摄像头是坏的

三.成功运行成功代码.

PS 后经过查询,看到很多博主教程中使用的都是Arduino 版本都是比本人使用的高,并且选择的工具开发板是AI -Thinker ESP32-CAM, 本人使用的1.8.5版本经过折腾始终没有出现AI-Thinker ESP32-CAM选项, 干脆升级到了 Arduino 2.1.0 版本
安装过程中使用魔法后依然报错Error: 2 UNKNOWN: Get “https://github.com/espressif/crosstool-NG/releases/download/esp-2021r2-patch5/xtensa-esp32-elf-gcc8_4_0-esp-2021r2-patch5-win64.zip”: dial tcp 20.205.243.166:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. 解决办法直接使浏览器贴入https://github.com/espressif/crosstool-NG/releases/download/esp-2021r2-patch5/xtensa-esp32-elf-gcc8_4_0-esp-2021r2-patch5-win64.zip, 下载下来后,粘贴到 C:\Users\Search\AppData\Local\Arduino15\staging\packages, 注:每个人电脑C:\Users\Search\路径不一样, 然后接着点击安装
新版本 2.0.11也尝试安装但是失败
文件首选项开发板管理器地址中的https://dl.espressif.com/dl/package_esp32_index.json,经过查询最新版本只能到1.0.6
https://arduino.me/packages/esp32.json经过查看最新版本能到2.0.9

猜测是导致2.0.11安装失败的原因吧,
