| Abstract: | In the programming of 51 MCU, for-loop delay time program segment in C language is used frequently, but the time span of the delay time program segment is not convenient to get. This article compares the C language to its corresponding assembly language of the for - loop, and then gets the deciding factors of the time span of delay time program segment, finaly gives the common method of how to estimate the delay time of for - loop in 51 MCU |
