ESP32-CAM模塊Arduino環(huán)境搭建測(cè)試

一.ESP32+OV2640攝像頭模塊CameraWebServer視頻查看

二.測(cè)試ESP32-CAM(后續(xù)稱cam模塊)代碼是否上傳執(zhí)行成功測(cè)試

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:上敘代碼是測(cè)試cam模塊代碼是否執(zhí)行成功

二.由于之前使用的是Arduino IDE 1.8.5版本,ESP32-CAM模塊上傳代碼后報(bào)錯(cuò) Camera probe failed with error 0x105(ESP_ERR_NOT_FOUND) Camera init failed with error 0x105 , 代碼如下

上敘代碼還是同樣報(bào)錯(cuò),導(dǎo)致一度懷疑攝像頭是壞的

三.成功運(yùn)行成功代碼.

PS 后經(jīng)過(guò)查詢,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,并且選擇的工具開(kāi)發(fā)板是AI -Thinker ESP32-CAM, 本人使用的1.8.5版本經(jīng)過(guò)折騰始終沒(méi)有出現(xiàn)AI-Thinker ESP32-CAM選項(xiàng), 干脆升級(jí)到了 Arduino 2.1.0 版本
安裝過(guò)程中使用魔法后依然報(bào)錯(cuò)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. 解決辦法直接使瀏覽器貼入https://github.com/espressif/crosstool-NG/releases/download/esp-2021r2-patch5/xtensa-esp32-elf-gcc8_4_0-esp-2021r2-patch5-win64.zip, 下載下來(lái)后,粘貼到 C:\Users\Search\AppData\Local\Arduino15\staging\packages, 注:每個(gè)人電腦C:\Users\Search\路徑不一樣, 然后接著點(diǎn)擊安裝
新版本 2.0.11也嘗試安裝但是失敗
文件首選項(xiàng)開(kāi)發(fā)板管理器地址中的https://dl.espressif.com/dl/package_esp32_index.json,經(jīng)過(guò)查詢最新版本只能到1.0.6
https://arduino.me/packages/esp32.json經(jīng)過(guò)查看最新版本能到2.0.9

猜測(cè)是導(dǎo)致2.0.11安裝失敗的原因吧,

當(dāng)你安裝成功后

四.運(yùn)行示例代碼注意事項(xiàng)

驗(yàn)證代碼過(guò)程中會(huì)報(bào)錯(cuò)項(xiàng)目太大了；閱讀以下頁(yè)面的提示減小文件大小。
