（1）频率测试功能：测频范围0.1H~200H。 测试精度：恒为百万分之一。 （2）脉宽测试功能：范围0.1us~1s，精度0.01us。 （3）占空比测试功能。-(1) the frequency of test functions: the scope of testing frequency 0.1H ~ 200H. Test accuracy: Constant for the parts per million. (2) pulse-width test functions: the scope of 0.1us ~ 1s, the accuracy of 0.01us. (3) duty cycle testing.

这个例子描述了如何配置和使用GPIOs通过STM32F1xxHAL_API。PD.07, PD.13, PD.03 and PD.04 IOs (configured in output pushpull mode)toggle in a forever loop.On STM3210C-EVAL RevC board these IOs are connected to LED1, LED2, LED3 and LED4.非常适合使用STM32做跨平台编程。对初学STM32的开发人员了解GPIO的配置很有帮助。
