There are two types of polling algorithms, (1) blocking and (2) non-blocking. (1) blocking functions will wait until a given event has occurred before moving on with code execution. Usually, delay ( ) functions are blocking because the purpose of the delay ( ) function is to suspend code execution for a given length of time.

The DAC block of STM32 micros can be operated in either with 8-bit or 12-bit resolution. The latter has greater precision while the former performs faster than latter. Each channel has its own converter and is not dependent on others. In STM32F103ZET6, there are two DAC channel outputs with two separate converters.

思路 简单说下思路,STM32自带一个两路独立输出的DAC。要输出正弦波,实质是要控制 DAC 以 v=sin(t)的正弦函数关系输出电压,其中 v 为电压输出,t 为时间。 而由于模拟信号连续而数字信号是离散的,所以使用 DAC 产生正弦波时,只能按一定时间间隔输出正弦曲线上的点,在该时间段内输出相同的.
