使用STM32G071RB拥抱拉伸力测量的未来

/*!
 * \file 
 * \brief Stretch Click example
 * 
 * # Description
 * The application is for stretch measuring 
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enables GPIO and ADC, turn off the LED and starts write log. 
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of Stretch Click board. Stretch Click reads and display ADC value.
