[ESP8266/ESP32] FireBeetle 2 ESP32-S3 测试1--连接透明显示屏、测试摄像头 |
本帖最后由 Anders项勇 于 2023-9-6 23:24 编辑 这次幸运抽取到试用FireBeetle 2 ESP32-S3,先测试其基本功能: 1.Arduino环境: arduino先安装ESP32-S3板子,但是连接国外网络原因,经常安装经常容易失败,可以按后面这个方法安装会快很多https://arduino.me/a/esp32 2.连接摄像头、1.51”透明单色OLED显示屏: 这么小的板子能同时连接摄像头和显示屏是不错的,头一次用1.51”透明单色OLED显示屏,显示效果不错。屏幕要安装U8g2_Arduino库文件。 测试当中有时会碰到“上传失败: 上传错误:exit status 2”,只要按下boot键,然后再重新上传就好了。有时刷程序报端口错误,看设备管理器里面端口一下接通一下不通,比较奇怪,换一根数据线好了,然后在换回原来数据线又好了,不知道何原因。 案例测试代码:/*! * @file Cube.ino * @brief Rotating 3D stereoscopic graphics * @n This is a simple rotating tetrahexon * * @copyright Copyright (c) 2010 DFRobot Co.Ltd (http://www.dfrobot.com) * @licence The MIT License (MIT) * @author [Ivey](Ivey.lu@dfrobot.com) * @maintainer [Fary](feng.yang@dfrobot.com) * @version V1.0 * @maintainer [Fary](feng.yang@dfrobot.com) * @version V1.0 * @date 2019-10-15 * @url https://github.com/DFRobot/U8g2_Arduino */ #include <Arduino.h> #include <U8g2lib.h> #include <SPI.h> /* * Display hardware IIC interface constructor *@param rotation:U8G2_R0 Not rotate, horizontally, draw direction from left to right U8G2_R1 Rotate clockwise 90 degrees, drawing direction from top to bottom U8G2_R2 Rotate 180 degrees clockwise, drawing in right-to-left directions U8G2_R3 Rotate clockwise 270 degrees, drawing direction from bottom to top U8G2_MIRROR Normal display of mirror content (v2.6.x version used above) Note: U8G2_MIRROR need to be used with setFlipMode(). *@param reset:U8x8_PIN_NONE Indicates that the pin is empty and no reset pin is used * Display hardware SPI interface constructor *@param Just connect the CS pin (pins are optional) *@param Just connect the DC pin (pins are optional) * */ #if defined ARDUINO_SAM_ZERO #define OLED_DC 7 #define OLED_CS 5 #define OLED_RST 6 /*ESP32 */ #elif defined(ESP32) #define OLED_DC D2 #define OLED_CS D6 #define OLED_RST D3 /*ESP8266*/ #elif defined(ESP8266) #define OLED_DC D4 #define OLED_CS D6 #define OLED_RST D5 /*AVR series board*/ #else #define OLED_DC 2 #define OLED_CS 3 #define OLED_RST 4 #endif U8G2_SSD1309_128X64_NONAME2_1_4W_HW_SPI u8g2(/* rotation=*/U8G2_R0, /* cs=*/ OLED_CS, /* dc=*/ OLED_DC,/* reset=*/OLED_RST);
