具体来说，在进行I/O操作之前，要循环地去检测该设备是否已经就绪。如果是，就向控制器发出一条命令，...
比如,如下截图,我精简了STM32CubeF1 的模板,将工程名称修改为:SmartSonic_HelloChirp,并在工程下新建了 Drivers/BSP 和 Drivers/chirpmicro 两个Groups。 3. 将SmartSonic_HelloChirp_Example_v1_31_0文件中 SmartSonic_HelloChirp_v1.31.0sourcedriverschirpmicro路径下的src 和 inc 文件夹拷贝到自己的STM32工程...
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...

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) ...
