But i few doubts.
1.When should i execute this command---killall rkipc
2.Previously i have downloaded the same link,do i have compile diffrent file for Pro/Max

If so please explain the complilation process for it

Thank you

git clone https://github.com/luckfox-eng29/luckfox_pico_rknn_example.git    

cd luckfox_pico_rknn_example/example/luckfox_retinaface_facenet/cpp_spi

#add_definitions(-DLUCKFOX_PICO_PLUS). 

mkdir build
cd build
make && make install

rkipc is a program that starts automatically when Luckfox-Pico boots up, used for quick functionality verification. Most applications requiring access to the camera need to close it.

As for Luckfox-Pico Pro/Max and Luckfox-Pico Plus, they have different external pin configurations. For ease of use, I've placed two compiled executable files in luckfox_pico_rknn_example/example/luckfox_retinaface_facenet/demo. If you need to compile them yourself, follow these steps:

1.Clone the program repository.

Code: Select all

git clone https://github.com/luckfox-eng29/luckfox_pico_rknn_example.git    

2.Navigate to luckfox_pico_rknn_example/example/luckfox_retinaface_facenet/cpp_spi.

Code: Select all

cd luckfox_pico_rknn_example/example/luckfox_retinaface_facenet/cpp_spi

3.Modify CMakeLists.txt by commenting out add_definitions(-DLUCKFOX_PICO_PLUS). This is because I use definitions to control the pin groups.

Code: Select all

#add_definitions(-DLUCKFOX_PICO_PLUS). 

4.Enter the build directory and execute the build command.

Code: Select all

mkdir build
cd build
make && make install

5.To send the output folder （luckfox_pico_rknn_example/example/luckfox_retinaface_facenet/cpp_spi/luckfox_retinaface_facenet_spi_demo）to the development board.
