时间显示 基于ssd1306 I2C 调用开源库 事半功倍

简介

FireBeetle 2 ESP32-S3可以使用Arduino IDE、ESP-IDF、MicroPython进行编程，C语言、python都可以轻松的操纵硬件。我选择以vscode为主，插件platformio，需要安装python3.
Purple Pi开发板通过J12排针提供了丰富的GPIO接口，包括UART、SPI、I2C、GPIO等（还包括DC5V、DC3.3V、GND）。

引脚概述

• GPIO：常规引脚
• Analog：模拟输入引脚
• ADC：模数转换
• TOUCH：触摸引脚
• SPI：SPI接口
• I2C：I2C接口
• UART：UART接口
• USB：USB接口
• JTAG：调试接口
• 3V3：3.3V稳压电源输出
• VCC：电源输入/输出
• 输入：5V DC输入为FireBeetle供电（无法为锂电池充电）
• 输出：5V-USB 供电时输出USB电压，3.7V-锂电池供电时输出锂电池电压
• GND：公共地引脚

克隆开源库

# 新建一个项目 命名为01SHOWTIME，如~/1SHOWTIME
mkdir ~/01SHOWTIME
cd ~/01SHOWTIME
# 新建platformio.ini 追加一些必要参数
[env:dfrobot_firebeetle2_esp32s3] >> platformio.ini 
platform = espressif32 >> platformio.ini  
board = dfrobot_firebeetle2_esp32s3 >> platformio.ini 
framework = arduino >> platformio.ini 
lib_deps =  /
    thingpulse/ESP8266 and ESP32 OLED driver for SSD1306 displays@^4.4.0 /
    paulstoffregen/Time@^1.6.1 >> platformio.ini 
# 配置platformio环境好了 只需要几个就行了
pio check # 检查一些依赖文件，并补充完整
# 复制一些例子到项目中，如下命令：
cp ".pio/libdeps/dfrobot_firebeetle2_esp32s3/ESP8266 and ESP32 OLED driver for SSD1306 displays/examples/SSD1306ClockDemo/images.h" ./src
cp ".pio/libdeps/dfrobot_firebeetle2_esp32s3/ESP8266 and ESP32 OLED driver for SSD1306 displays/examples/SSD1306ClockDemo/SSD1306ClockDemo.ino" ./src/main.c # 需要换名字由ino后缀改为main.c
pio run  # 就这样烧录到开发板上面，你说简不简单不
