详细说明： esp32-freertos-sdk 工具包 See the Getting Started guide links above for a detailed setup guide. This is a quick reference for common commands when working with ESP-IDF projects: Setup Build Environment (See Getting Started guide for a full list of required steps with details.) Install host build dependencies mentioned in Getting Sta rted guide. Add tools/ directory to the PATH Run python -m pip install -r requirements.txt to install Python dependencies Configuring the Project idf.py menuconfig Opens a text-based configuration menu for the project. Use up & down arrow keys to navigate the menu. Use Enter key to go into a submenu, Escape key to go out or to exit. Type ? to see a help screen. Enter key exits the help screen. Use Space key, or Y and N keys to enable (Yes) and disable (No) configuration items with checkboxes "[*]" Pressing ? while highlighting a configuration item displays help about that item. Type / to search the configuration items. Once done configuring, press Escape multiple times to exit and say "Yes" to save the new configuration when prompted. Compiling the Project idf.py build ... will compile app, bootloader and generate a partition table based on the config. Flashing the Project When the build finishes, it will print a command line to use esptool.py to flash the chip. However you can also do this automatically by running: idf.py -p PORT flash Replace PORT with the name of your serial port (like COM3 on Windows, /dev/ttyUSB0 on Linux, or /dev/cu.usbserial-X on MacOS. If the -p option is left out, idf.py flash will try to flash the first available serial port. This will flash the entire project (app, bootloader and partition table) to a new chip. The settings for serial port flashing can be configured with idf.py menuconfig. You dont need to run idf.py build before running idf.py flash, idf.py flash will automatically rebuild anything which needs it. Viewing Serial Output The idf.py monitor target uses the idf_monitor tool to display serial output from the ESP32. idf_monitor also has a range of features to decode crash output and interact with the device. Check the documentation page for details. Exit the monitor by typing Ctrl-]. To build, flash and monitor output in one pass, you can run: idf.py flash monitor Compiling & Flashing Only the App After the initial flash, you may just want to build and flash just your app, not the bootloader and partition table: idf.py app - build just the app. idf.py app-flash - flash just the app. idf.py app-flash will automatically rebuild the app if any source files have changed. (In normal development theres no downside to reflashing the bootloader and partition table each time, if they havent changed.) Erasing Flash The idf.py flash target does not erase the entire flash contents. However it is sometimes useful to set the device back to a totally erased state, particularly when making partition table changes or OTA app updates. To erase the entire flash, run idf.py erase_flash. This can be combined with other targets, ie idf.py -p PORT erase_flash flash will erase everything and then re-flash the new app, bootloader and partition table.
