Timer2 call with Timer2 disabled

[Jan Lichtenbelt]

I use timer2 and timer4. I get silly result using timer2 and timer4.

To find out what happens I disabled (did not enabled) timer 2 by means of goto label A in macro "Send_Bits". Nevertheless the timer2 interrupt macro "Timer2_Interrupt" is called by the program. This can easily be shown because this interrupt macro is the only one which can change the output state of B0. And I see B0 changing with 77.5 Khz.

How can help me?


Kind regards

PS. In the meanwhile I produced the same program also in Flowcode5. That one works as it should be / as expected.

Hi Jan,

Think I have spotted the problem. The timer 4 interrupt is calling the timer 2 macro. Just noticed it by comparing the C code produced by v5 and v6.

If one looks to long to a problem, one will miss the details.

Thanks a lot for helping. Indeed the wrong interrupt macro has been used for timer4.

Kind regards

Jan
