# framebuffer_OpenCV
This is a replica of the CoreMP135_framebuffer_OpenCV project by nnn112358, used to demonstrate the application of OpenCV on CoreMP135.

This project requires the use of a higher version of gcc.

```bash
sudo apt install arm-linux-gnueabihf-g++ arm-linux-gnueabihf-gcc

scons

scons push
```

### result in CoreMP135
```bash
