/*
 * 测试温度传感器驱动的读取功能
 *
 * 1. 查找名为 "ts" 的温度传感器设备。
 * 2. 打开设备，并确保设备成功初始化。
 * 3. 通过 rt_device_read 接口读取温度数据：
 *    - 每次读取的数据类型为 double；
 *    - 读取操作执行 5 次，以连续获取温度值；
 *    - 每次读取后打印温度值，格式为 "Temperature = XX.XX C"。
 * 4. 读取完成后，关闭设备并释放申请的内存。
 *
 * 硬件说明：
 * - 本测试基于 K230-01studio 开发板；
 * - 温度传感器为板载设备；
 * - 驱动已将硬件寄存器读取的原始 ADC 值转换为摄氏度的 double 值；
 * - 测试过程中，可在串口终端实时观察温度变化。
