The interrupt request handler function is ruled to name after these predefined vectors. For example, I'm configuring extern interrupt from PA0, then I need to name my interrupt request handler function as: void

相反的如果我们从st自带的hal库中打开一个Example,可以看到st的hal库中的时钟设置部分都是放在main函数的开头的。 其实道理是一样的,因为systemInit执行完了后接着就会执行main函数了,所以时钟初始化放在systeminit的末位和放在main的开头是等效的。 好了,开始适配晶振。由于我使用的是12MHz的晶振,通过12MHz*6=72...
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...

Several lowpower modes are available to save power when the CPU does not need to be kept running, for example when waiting for an external event. It is up to the user to select the mode that gives the best compromise between low-power consumption, short startup time and available wakeup ...
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) and the low speed APB (APB1) ains. The um...
