What is the difference between pyb.delay and time.sleep? [Copy link]

 

It’s still Xiaobai’s problem.

When learning micropython, I came across pyb.delay and time.sleep, both of which can achieve delay. What is the difference between them, or what impact do they have on the efficiency of the program?

I first came into contact with assembly language, and I have always been unsure about what high-level languages are doing. Recently, I learned micropython and felt that it was very efficient when writing things.

There is no difference, they are all delays, the same as the delay in C language.

There is a difference. If it is a delay in an IC driver, it is strongly recommended to use pyb.delay, which has higher accuracy than time.sleep. I had a driver that was unstable when using time.sleep and would timeout. I changed it to pyb.delay and this problem did not occur.

pyb.delay(ms) delay in milliseconds, time.sleep(s) delay in seconds, the units are different, I am also learning, for reference only!

Try to use the time library for delay, which is more versatile. Many of the previous pyb functions have been put into machine, time, etc.
