HardFault with FreeRTOS at STM32 - New Project

WebI'm using the ADC channels (12-bit resolution) of a STM32F0 microcontroller to read voltage values in three different points of a board. What I want to do is to read the values every 2 seconds (I have 2 seconds to read the values in the three points) and send them by the UART interface. Web输入捕获的考题十分明确，就是测量输入脉冲波形的占空比和频率，对我们的板子而言，就是检测板载的两个信号发生器产生的信号：具体来说就是使用pa15和pb4来做输入捕获。输入捕获能够对输入信号的上升沿和下降沿进行捕获，并且记录下捕获时定时器的数值以及触发中断。
