使用MQ-8和PIC18F57Q43监测氢气泄漏以提高安全性

/*!
 * @file main.c
 * @brief Hydrogen Click Example.
 *
 * # Description
 * The demo application shows the reading of the adc 
 * values given by the sensors.
 * 
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Configuring Clicks and log objects.
 * 
 * ## Application Task
 * Reads the adc value and prints in two forms (DEC and HEX).
