# Quick Start

## Compile and Run the Test Program.

Boot the development board and run the Debian system. Once the system is up, clone the TB-RK3588SD-Power code repository.

  ```
  apt-get update && apt-get install git build-essential
  git clone https://github.com/rockchip-toybrick/sd_power.git
  ```

After completing the above steps, you will obtain a directory named sd_power. 

Compile sd_power:

  ```
  cd sd_power
  make
  ```
Running test program:
  ```
  chmod a+x sample
  ./sample
  ```
The operation result is as follows:

The main page displays the ToyBrick logo.

- When button 1 is pressed, the red RGB LED lights up, and the network information display page is entered. At this point, pressing buttons 1 and 2 toggles between displaying different network interfaces and IPs. Pressing button 3 returns to the main page.
- When button 2 is pressed, the blue RGB LED lights up, and the system load display page is entered. At this point, pressing buttons 1 and 2 toggles between displaying different CPU loads. Pressing button 3 returns to the main page.
- When button 2 (note: this should be button 3 for clarity) is pressed, the green RGB LED lights up, and the six-axis sensor display page is entered. At this point, pressing buttons 1 and 2 toggles between displaying gyroscope and accelerometer status. Pressing button 3 returns to the main page.
