Timer2 - Printf function

Ed Lau

Hi,

Sorry for the mistake. Here is the question again:

I need to use 89C52 timer2 counter function. However, when I use the timer2, I cannot use printf function to debug my program, that is, no display output. However, printf function works fine for timer0 and timer1 function.

How I can use printf within the timer2 program?

Thanks

Ed

    I wrote timer0, timer1 and timer2 counter all in one program. When I invoke timer0, or timer1, I can use printf in the main program and the ISR. However, when I invoke timer2, I cannot use the printf in the ISR and the main program. System not hang, but just ignore to display.

    Any idea?
