Code is assembly language used to achieve a button control the timer start and suspension, are written in external interrupt and timer interrupt, external interrupt 0 each to a falling edge, can realize the function of pause and start, respectively, with C8051F310 debugging, point P0.1 feet, when the first falling edge, the timer is suspended, but then the computer is very loud, and then crashed and all sorts of debugging window are not response but, in fact, I step through the result of well realize the expected function, using 89 c51 single-chip computer simulation also didn't appear afore-mentioned problems,
Freshman for bosses to give directions

CodePudding user response:

Is the trigger mode? Whether you need waveform dissipation shaking? Interrupt the flip a state output pin oscilloscope see

CodePudding user response:

reference

then all kinds of debugging window not response crashed

The general conditions is something wrong with the simulator, such as no electricity
