合宙ESP32C3硬件配置信息串口打印輸出

ESP32C3硬件簡介

ESP32-C3 搭載 RISC-V 32 比特單核處理器，時鐘頻率高達 160 MHz。具有 22 個可編程 GPIO 管脚、內置 400 KB SRAM,集成 2.4 GHz Wi-Fi 和支持長距離的 Bluetooth 5 (LE),支持藍牙 Mesh (Bluetooth Mesh) 協議和樂鑫 Wi-Fi Mesh.

• ESP32C3資料文檔
• https://www.espressif.com.cn/sites/default/files/documentation/esp32-c3_datasheet_cn.pdf
• 經檢測，通過Arduino IDE編譯上傳的代碼可以打印外置spi flash 容量，而通過VSCode PIO編譯上傳的代碼就查詢不到有關flash容量的信息。

  delay(1000); // wait for a second

  digitalWrite(12, LOW);    // turn the LED off by making the voltage LOW

• 基於VSCode PIO編譯相同的代碼

程序代碼編譯只占1.7%符合自定義分區錶的配置。但是在VSCode PIO編譯上傳的代碼有一個問題，就是通過函數無法讀取外置SPI flash 容量。
