Thanks for clarifying this.

Hi.
When is it an advantage to create a project with multiple compilation units and how effective is it compared to building a regular single project?

What a shocker. Of course. 'PER_SECOND' should be fixed since this is what determines the value for the counter. All that was required was a variable to set led_count a rate. Enter led_time.

Regar ...

Start using your brain a bit.

All you need to do is set the LED rate with a global variable, instead of with a define. Change the value of this variable in your main.

Ok, this part I understood. ...

Hi, Ttelmah,
One last help buddy.
Considering your code below which I made slight changes to fit the LED rate for my purposes:

#define PER_SECOND 126
int8 count;
#int_timer0
void TimerLED( ...

Thanks, I will try this.
Best regards.

Please, disconsider what I have said above.
This offset was from PT simulator. Before leaving home now, I did it with the protoboard and it was fine. Reading 4999-5000Hz.

Since we are into this, o ...

First, thank you very much.

Your original 'per second value'

#define PER_SECOND 125

was displaying an offset in the frequency value. 5000Hz signal was shown as 4960Hz.
I changed this value t ...

Yes, I don't know enough C to solve my problems. But I am striving. I knew nothing in early december. Thanks to some reading in this forum, today I am in the end part of my first code which is not so ...

I wrote another code only featuring the timer0 interrupt and the counter instruction in the main. It worked now.
I used Ttelmah's code, but another similar code also worked.

Well, I spent all day away from my protoboard and was simulating everyting in PT.
I just got home and put the code to test in the hardware. Actually the frequency counter is indeed working. But not t ...

Thanks, you're right. Should be 256 max. I was playing with the led rate and got lost in the value limit.

I just set it to 6 (256-6), but no change. Frequency counter offset value decreased but sti ...

I've got a problem with a frequency counter not working right when the LED starts blinking.
I have this LED in a TIMER0 interrupt and the frequency counter in the main code. When the interrupt is exc ...

I think I might have found something that I believe it's not included in the guidelines. It relates to Proteus.
I changed the delays of the LEDs making them longer and the PWM pulses shorter. The LEd ...
