记录一下esp32S3使用PlatformIO开发的常用配置

• 指定板子型号，开发框架

  [env:esp32-s3-devkitc-1]
  platform = espressif32
  board = esp32-s3-devkitc-1
  framework = arduino

• 设置8M flash

  board_build.arduino.partitions = default_8MB.csv
  board_upload.flash_size = 8MB
  board_build.flash_mode = dio

• 开启PSRAM，并设置C++20

  build_unflags = -std=gnu++11
  board_build.arduino.memory_type = qio_opi
  build_flags =
                 -DBOARD_HAS_PSRAM
                 -std=gnu++2a
                 -DCORE_DEBUG_LEVEL=ARDUHAL_LOG_LEVEL_VERBOSE
                 -DARDUINO_USB_MODE=1
                 -DARDUINO_USB_CDC_ON_BOOT=1

  其中，board_build.arduino.memory_type根据PARAM大小设置，如果使用2MB大小，则设置为qio_qspi；如果大小为8MB，则设置为qio_opi。

• 开启串口监视器解码esp32异常栈 ,显示时间 ,显示debug信息等

  monitor_filters = esp32_exception_decoder, time, debug
