1# Niobe407开发板OpenHarmony外设编程开发——RNG
2随机数发生器（RNG）是一个以连续模拟噪声为基础的随机数发生器，在主机读数时提供一个 32 位的随机数。
3本示例将演示如何在Niobe407开发板上通过rng获取随机数。

6## 编译调试
7- 进入//kernel/liteos_m目录, 在menuconfig配置中进入如下选项:
8
9 `(Top) → Platform → Board Selection → select board niobe407 → use talkweb niobe407 application → niobe407 application choose`
10
11- 选择 `102_peripheral_rng_number`
12
13- 回到sdk根目录，执行`hb build -f`脚本进行编译。
