合宙ESP32C3硬件配置信息串口打印输出

🌴ESP32C3硬件简介

📝ESP32-C3 搭载 RISC-V 32 位单核处理器，时钟频率高达 160 MHz。具有 22 个可编程 GPIO 管脚、内置 400 KB SRAM,集成 2.4 GHz Wi-Fi 和支持长距离的 Bluetooth 5 (LE),支持蓝牙 Mesh (Bluetooth Mesh) 协议和乐鑫 Wi-Fi Mesh.

• 🔖ESP32C3资料文档
• https://www.espressif.com.cn/sites/default/files/documentation/esp32-c3_datasheet_cn.pdf
• ✨经检测，通过Arduino IDE编译上传的代码可以打印外置spi flash 容量，而通过VSCode PIO编译上传的代码就查询不到有关flash容量的信息。
• 📢另外需要注意的地方：通过Arduino平台编译上传代码时，flash Mode一定要选择DIO模式，否则会无限重启。

• 🌼基于VSCode PIO编译相同的代码

🌿程序代码编译只占1.7%符合自定义分区表的配置。但是在VSCode PIO编译上传的代码有一个问题，就是通过函数无法读取外置SPI flash 容量。
