使用LTC2986和STM32F410RB实现无与伦比的温度监测精度和可靠性

/*!
 * @file main.c
 * @brief TempProbe Click example
 *
 * # Description
 * This is an example that demonstrates the use of the Temp Probe Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes SPI interface, setting temperature format to celsius and performs a device 
 * configuration for proper functioning and configures the desired channels. 
 *
 * ## Application Task
 * Measure temperatures from all sensors and display the measurements on the serial port.
