                             Sample Description
================================================================================
功能描述：
该样例演示了POSIF模块的霍尔功能使用配置，获取宽度，并配置霍尔宽度最大值，超过最大值配置产生中断
LED1每隔1s翻转一次。

Function descriptions:
This example demonstrates the configuration of the Hall function of the POSIF module, 
obtaining the width and configuring the maximum value of the Hall width. If the maximum value is exceeded, 
an interrupt will be generated. LED1 flips every 1 second.
