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...
问带有定时器和DMA的STM32F103脉宽调制用于WS2812中断功能的不断调用EN我正试图用一个定时器产生的脉宽调...
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...
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...
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 ...

A software interrupt is generated if enabled. Similarly, full interrupt management of the PLL clock entry is available 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) ...
1. 从官网获取 SmartSonic_HelloChirp_Example_v1_31_0.exe 源码(CHx01 官网源码的硬件平台MCU: ATSAMG55;IDE:MicrochipStudio) 2. 获取一个STM32F103CB 的例程,比如我直接使用 STM32CubeF1 的模板。(当然你也可以用 STM32CubeIDE 创建一个工程)在这之前,假设你已经掌握了KeilIDE 工程下的文件添加、编译等...
