WebThe GPIO functions require you to input variables in order to specify both a port and a pin. For ports, the variable GPIOx is used, where the x is replaced with the port letter (ranging from A to F). For pins, the variable GPIO_Pin_n is used, where the n is replaced with the pin number (ranging from 0 to 15) To configure and use a port pin: Web本文聊聊上海矽睿产的加速度传感器QMA6100P的使用。 1、特性. 高集成，小尺寸封装：2 x 2 x 0.95 mm LGA 14位数模转化，低噪声 · driving directions google ma
