This chapter mainly introduces how to use the 8ms sdk for local development. As for UI development, please refer to the 8ms platform documentation.

## Download sdk

```
git clone https://github.com/wireless-tag-com/8ms-sigmastar.git

Copy the debugged screen parameters (header file) directly to 8ms-sigmastar/ssd20x/panel.h, which is the debugged parameters for 7-inch screen by default

```
cd 8ms-sigmastar
make CHIP=ssd20x
```

The executable file is located in bin/qmsd-demo

```
cd /tmp
tftp -g 192.168.1.111 -r qmsd-demo
