Web21 jun. 2024 · STC15系列 单片机 的外部中断0（INT0）和外部中断1（INT1）的触发有两种方式，上升沿和下降沿均可触发方式和仅下降沿触发方式。 在实际应用中，有时候需要上升沿触发。 这时有两种方案可以解决。 1.将触发方式设置成仅下降沿触发。 当外部电路产生一个上升沿时，通过硬件电路加一个三极管进行反向变成下降沿。 2.这种方法不需要改变 … Web0. The integral of 0 is C, because the derivative of C is zero. Also, it makes sense logically if you recall the fact that the derivative of the function is the function's slope, because any function f (x)=C will have a slope of zero at point on the function. Therefore ∫0 dx = C. (you can say C+C, which is still just C). Web10 jun. 2016 · An integer 0 cast to a pointer is also a null pointer. A system could have many different (bit-wise) null pointers.
