Get Started

What You Need
To develop applications for module you need:

• 1 x ESP32-C6-MINI-1U
• 1 x Espressif RF testing board
• 1 x USB-to-Serial board
• 1 x Micro-USB cable
• 1 x PC running Linux

In this user guide, we take Linux operating system as an example. For more information about the configuration on Windows and macOS, please refer to ESP- IDF Programming Guide.

Hardware Connection

1. Solder the ESP32-C6-MINI-1U module to the RF testing board as shown in Figure 2.
2. Connect the RF testing board to the USB-to-Serial board via TXD, RXD, and GND.
3. Connect the USB-to-Serial board to the PC.
4. Connect the RF testing board to the PC or a power adapter to enable 5 V power supply, via the Micro-USB cable.
5. During download, connect IO9 to GND via a jumper. Then, turn ”ON” the testing board.
6. Download firmware into flash. For details, see the sections below.
7. After download, remove the jumper on IO9 and GND.
8. Power up the RF testing board again. The module will switch to working mode. The chip will read programs from flash upon initialization.

Note:
IO9 is internally logic high. If IO9 is set to pull-up, the Boot mode is selected. If this pin is pull-down or left floating, the Download mode is selected. For more information on ESP32-C6-MINI-1U, please refer to ESP32-C6 Series Datasheet.

Set up Development Environment
The Espressif IoT Development Framework (ESP-IDF for short) is a framework for developing applications based on the Espressif ESP32. Users can develop applications with ESP32-C6 in Windows/Linux/macOS based on ESP-IDF. Here we take Linux operating system as an example.

Install Prerequisites
To compile with ESP-IDF you need to get the following packages:

• CentOS 7 & 8:
  • sudo yum -y update && sudo yum install git wget flex bison gperf python3  cmake ninja-build ccache dfu-util libusbx
• Ubuntu and Debian:
  • sudo apt-get install git wget flex bison gperf python3 python3-venv cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0
• Arch:
  • sudo pacman -S –needed gcc git make flex bison gperf python cmake ninja ccache dfu-util libusb

Note

• This guide uses the directory ~/esp on Linux as an installation folder for ESP-IDF.
• Keep in mind that ESP-IDF does not support spaces in paths.

Get ESP-IDF
To build applications for ESP32-C6-MINI-1U module, you need the software libraries provided by Espressif in ESP-IDF repository.
To get ESP-IDF, create an installation directory (~/esp) to download ESP-IDF to and clone the repository with ‘git clone’:

1. mkdir -p ~/esp
2. cd ~/esp
3. git clone –recursive https://github.com/espressif/esp-idf.git

ESP-IDF will be downloaded into ~/esp/esp-idf. Consult ESP-IDF Versions for information about which ESP-IDF version to use in a given situation.

Set up Tools
Aside from the ESP-IDF, you also need to install the tools used by ESP-IDF, such as the compiler, debugger, Python packages, etc. ESP-IDF provides a script named ’install.sh’ to help set up the tools in one go.

1. cd ~/esp/esp-idf
2. ./install.sh esp32c6

Set up Environment Variables
The installed tools are not yet added to the PATH environment variable. To make the tools usable from the command line, some environment variables must be set. ESP-IDF provides another script ’export.sh’ which does that. In the terminal where you are going to use ESP-IDF, run:

1. $HOME/esp/esp-idf/export.sh

Now everything is ready, you can build your first project on ESP32-C6-MINI-1U module.

Create Your First Project

Start a Project
Now you are ready to prepare your application for ESP32-C6-MINI-1U module. You can start with get-started/hello_world project from examples directory in ESP- IDF.
Copy get-started/hello_world to ~/esp directory:

1. cd ~/esp
2. cp -r $IDF_PATH/examples/get-started/hello_world .

There is a range of example projects in the examples directory in ESP-IDF. You can copy any project in the same way as presented above and run it. It is also possible to build examples in-place, without copying them first.

Connect Your Device
Now connect your module to the computer and check under what serial port the module is visible. Serial ports in Linux start with ‘/dev/tty’ in their names. Run the command below two times, first with the board unplugged, then with plugged in. The port which appears the second time is the one you need:

1. ls /dev/tty*

Note:
Keep the port name handy as you will need it in the next steps.

Configure
Navigate to your ‘hello_world’ directory from Step 3.4.1. Start a Project, set ESP32-C6 chip as the target and run the project configuration utility ‘menuconfig’.

1. cd ~/esp/hello_world
2. idf.py set-target esp32c6
3. idf.py menuconfig

Setting the target with ‘idf.py set-target ESP32-C6’ should be done once, after opening a new project. If the project contains some existing builds and configuration, they will be cleared and initialized. The target may be saved in environment variable to skip this step at all. See Selecting the Target for additional information.
If the previous steps have been done correctly, the following menu appears:

You are using this menu to set up project specific variables, e.g. Wi-Fi network name and password, the processor speed, etc. Setting up the project with menuconfig may be skipped for “hello_word”. This example will run with default configuration
The colors of the menu could be different in your terminal. You can change the appearance with the option ‘-̉-style’̉. Please run ‘idf.py menuconfig -̉-help’̉ for further information.

Build the Project
Build the project by running:

1 idf.py build

This command will compile the application and all ESP-IDF components, then it will generate the bootloader, partition table, and application binaries.

1. $ idf.py build
2. Running cmake in directory /path/to/hello_world/build
3. Executing ”cmake -G Ninja –warn-uninitialized /path/to/hello_world”…
4. Warn about uninitialized values.

17. or run ’idf.py -p PORT flash’

If there are no errors, the build will finish by generating the firmware binary .bin file.

Flash onto the Device
Flash the binaries that you just built onto your module by running:

1. idf.py -p PORT [-b BAUD] flash
   Replace PORT with your ESP32-C6 board’s serial port name from Step: Connect Your Device.
   You can also change the flasher baud rate by replacing BAUD with the baud rate you need. The default baud rate is 460800.
   For more information on idf.py arguments, see idf.py.

Note:
The option ‘flash‘ automatically builds and flashes the project, so running ‘idf.py build‘ is not necessary.

When flashing, you will see the output log similar to the following:
