Working with ESP-IDF

The following development system defaults to Windows, and it is recommended to use the VSCode plug-in for development.

Develop with VSCode

Install VSCode

• Open the VSCode website to download according to the corresponding system and system bits.

• After running the installation package, the rest can be installed by default, but here for a better experience, it is recommended to check the box here in the 1, 2, and 3 items.
  • After enabling the 1 and 2 items, you can directly open the VScode by right-clicking the file or the directory to improve your experience.
  • After enabling the 3 items, you can directly select VSCode when choosing how to open,

Install Espressif IDF Plug-in

• Note: Currently the latest version of the plugin is V1.6.4, users can choose the same version as us for a consistent experience!
• Open VSCode, use Shift+Ctrl+X to enter the plug-in manager.

• In the search bar, enter Espressif IDF to select the corresponding plug-in and click "Install".

• Press F1 to input:

esp-idf: configure esp-idf extension

• Select express (this guide is for users who install it for the first time).

• Select download sever.

• Select the version of ESP-IDF you want to use now, we choose the latest V5.1.1 (note that only after V5.1 did ESP-IDF start to support ESP32-C6).

• The following two are the installation paths respectively for the ESP-IDF container directory and the ESP-IDF Tools directory.

• Note: If you have installed ESP-IDF before, or failed to do so, please be sure to delete the file completely or create a new path without Chinese.
• After configuring, click "Install" to download:

• Enter the download interface, and then it will automatically install the corresponding tools and environment, just wait for a second.

• After the installation is complete, you will enter the following interface, indicating that the installation is finished.

Official Demo Usage GUIDE

Create Demo (Demo Example)

• Press F1 to enter:

esp-idf:show examples projects

• Select the corresponding IDF version:

• Take the Hello World demo as an example:
  • ①Select the corresponding demo.
  • ②Its readme will state what chip the routine applies to (how the demo is used with the file structure is described below, omitted here).
  • ③Click to create the demo.

Select the path to place the demo, and the folder name should be aligned with the demo name.

Modify COM Port

• The corresponding COM ports are shown here, click to modify them.
• Please select the COM ports according to your device. It is recommended to use the COM port corresponding to the USB connector. (You can view it from the device manager.)
• In case of a download failure, please press the reset button for more than 1 second and wait for the PC to recognize the device again before downloading once more.

• Select the project or demo to use:

• Then we finish the modification of the COM ports.

Modify the Driver Object

• The driver object is displayed here, and you can modify it by clicking on it.
• Select the project or demo to use.

• Wait for a minute after clicking.

• Select the object we need to drive, which is our main chip ESP32C6.

• Choose the path to openocd, it doesn't affect us here, so let's just choose one at random.

The Rest of the Status Bar

• ①SDK configuration editor, supports modifying most functions of ESP-IDF.
• ②All cleanup, and clear all compiled files.
  
• ③Compile.
• ④Current download mode, default is UART.
• ⑤Flash the current firmware, please do it after compiling.
• ⑥Open the serial port monitor, used to view the serial port information.
• ⑦All-in-one button, compile, burn, open the serial monitor (most commonly used for debugging).

Compile, Program, Serial Port Monitoring

• Click on the all-in-one button we described before to compile, program, and open the serial port monitor.

• It may take a long time to compile especially for the first time.

• During this process, the ESP-IDF may take up a lot of CPU resources, so it may cause the system to lag.
• If it is the first time to burn the program for a new project, you will need to select the download method, and select UART.

• This can also be changed later in the Download Methods section (click on it to bring up the options).

• As it comes with the onboard automatic download circuit, there is no need for manual operation to download automatically.

• After successful download, automatically enter the serial monitor, you can see the chip output the corresponding information and be prompted to restart after 10S.
