On chip microcontroller timer T1 on P1.0 pin continuous square-wave cycle is 100 ms, a crystal vibration frequency of 12 MHZ, and requirements;
(1) use a timer interrupt, timer work requires the use of works 1;
(2) of the square wave per cycle of high level and low level time 500 ms
(3) requires the use of interrupt service routine implementation effect,

CodePudding user response:

What type of MCU?

CodePudding user response:

On chip microcontroller timer T1 on P1.0 pin continuous square-wave cycle is 100 ms,
(2) square wave of each cycle of high level and low level time 500 ms (the cycle of this sentence is 1000 ms=1 s)
The above two sentences have problems, whether the sentence is right,

CodePudding user response:

This function does not need to interrupt, timer configuration is achieved, but maybe want to take an examination of the interrupt, formulate a 50 ms timer interrupt, interrupt response program to take the p1.0 level,
