中断模式 The interrupt method is an efficient way to do ADC conversion in a non-blocking manner, so the CPU can resume executing the main code routine until the ADC completes the conversion and fires an interrupt signal so the CPU can switch to the ISR context and save the conversion result...

A software interrupt is generated if enabled. Similarly, full interrupt management of the PLL clock entry is ailable when necessary (for example with failure of an indirectly used external oscillator). Several prescalers allow the configuration of the AHB frequency, the high speed APB (APB2) ...

添加peripheralpin 在PinMap_UART_TX中添加 该句一定要放在结束符 之前 同理在PinMap_UART_RX中添加 {PD_2, UART_5, STM_PIN_DATA(STM_MODE_INPUT, GPIO_PULLUP, 0)}, 关于STM_PIN_DATA(),这其实是一个宏定义,最后一个参数是一个复用的索引表,这个索引表在pinmap文件中有所体现。
