### Hardware Environment

- `CanMV-K230-V1.x / CanMV-K230-V2.x / K230-UNSIP-LPx-EVB-V1.x`

### Source Code Location

The source code path is located at `k230_sdk/src/reference/fancy_poc`, with the directory structure as follows:

```shell
.
├── ai_scale
├── build_app.sh
├── cmake
├── CMakeLists.txt
├── face_recognition
├── finger_reader
├── housekeeper
├── meta_hand
├── meta_human
├── multimodal_chat_robot
└── version
```

### Compiling and Running the Program

#### a. Self-compiled Board Image

- Ensure that you have built the docker container and image according to the [K230 SDK official instructions](https://github.com/kendryte/k230_sdk).
- Navigate to k230_sdk/src/reference/fancy_poc.
- Execute build_app.sh, which will generate the corresponding large core and small core files in the k230_sdk/src/reference/fancy_poc/k230_bin directory.
- Select the POC executable file you want to reference from the k230_bin directory and copy it to the development board. (Refer to each POC's readme for the corresponding executable program).
- For the kmodel and other binary files required for each POC on the board, refer to the src/download.sh in the POC directory for download and use.

#### b. Direct Download of Official Board Image

1. Ensure that you have built the docker container according to the [K230 SDK official instructions](https://github.com/kendryte/k230_sdk).
1. Download the image from the [official resource library](https://developer.canaan-creative.com/resource).
1. Prepare the environment:

```bash
cd k230_sdk
make prepare_sourcecode # (If previously executed, please ignore)
make mpp
# Execute different commands based on the model of the development board
# If the model is CanMV-K230-V1.x, execute the following command
make CONF=k230_canmv_defconfig prepare_memory
# If the model is CanMV-K230-V2.x, execute the following command
make CONF=k230_canmv_v2_defconfig prepare_memory
# If the model is K230-xxx-xxx-EVB-V1.x, execute the following command
make CONF=k230_evb_defconfig prepare_memory
cd k230_sdk/src/reference/fancy_poc
```

- Execute build_app.sh, which will generate the corresponding large core and small core files in the k230_sdk/src/reference/fancy_poc/k230_bin directory.
- Select the POC executable file you want to reference from the k230_bin directory and copy it to the development board. (Refer to each POC's readme for the corresponding executable program).
- For the kmodel and other binary files required for each POC on the board, refer to the src/download.sh in the POC directory for download and use.
