FireBeetle 2 ESP32-S3 相机图1


本次测试的是将摄像头与屏幕结合起来,实现监控相机功能。
一、测试屏幕显示
使用DFRobot_GDL库自带的“bitmap”示例。
引脚定义:
#define TFT_DC  3
#define TFT_CS  18
#define TFT_RST 38
#define TFT_BL  47
屏幕定义:
DFRobot_ILI9341_240x320_HW_SPI  screen(/*dc=*/TFT_DC,/*cs=*/TFT_CS,/*rst=*/TFT_RST);

示例主程序:
  1. /*!
  2. * @file bitmap.ino
  3. * @brief Draw monochrome, colorful, and grayscale images based on the image array generated by the bitmap software.
  4. * [url=home.php?mod=space&uid=821650]@N[/url] The demo requires to be run on a main-controller with 40000 bytes of dynamic memory, like FireBeetle-ESP8266 and FireBeetle-ESP32 since there are 380,000 bytes in this project.
  5. * [url=home.php?mod=space&uid=843077]@n[/url] This demo supports mainboard FireBeetle-ESP32, FireBeetle-ESP8266, and FireBeetle-M0.

二、摄像头与屏幕结合
1、需要Arduino IDE安装GFX_Library for Arduino、TJpg_Decoder、DFRobot_AXP313A库。
2、引脚定义
  1. #define TFT_CS     18
  2. #define TFT_RST  38
  3. #define TFT_DC     3
  4. #define TFT_MOSI   15
  5. #define TFT_SCK    17
  6. #define TFT_MISO   16
  7. #define PIN_BTN 47
复制代码

3、要设置摄像头供电
  1. while (axp.begin() != 0)
  2.   {
  3.     Serial.println("init error");
  4.     delay(1000);
  5.   }
  6.   axp.enableCameraPower(axp.eOV2640);
复制代码

4、图像质量设置config.jpeg_quality = 12;
值越小越质量越好,但易出现重启。经测试小于6会出问题。
