Hi Benj
Thanks for all the info.
Now I am getting a bit more understanding and I am busy changing the code.
Works great so far.
However I ran into problems without getting any warning in the "Building CASM file"

Just one more question.
The MOD function is a no no in interrupt macros. And others ...

Hi Benj.
So basically it would be best to be safe would be to just use the + and minus in a timer interrupt and do the rest of the calculation all in the main program.
Will it also help to use a different variable outside the interrupt. For example you have the variable "Minutes" in the interrupt ...

Hi
I do not understand fully.
If I use the plus function like (+) In an interrupt I must not use the plus function at all in the main macro?
Or I must not use the plus function for the same variable? Etc.

Hi
Thanks for the info.
So I just learned that you should not use the division function within the timer interrupt.
Could you please point me to some more info what functions I should not use in timer interrupt?
Is division function anything like this (hours=minutes/60) etc.

Best Regards:

Hi
Thanks for the modified code.
You basically put all the calculations back into the Timer macro. Except the (dislpay=0)
And then it all works fine. Also I would not want to split the Hour an tenth. Because I want to use that number to calculate average amp usage in real time.
Now I am trying to ...

I don't think Watchdogtimer is resetting, numbers like temperature and other numbers like other counters are not affected.

Hi Benj.
I found some code of concern.
Attached is the code of concern.
This code is about a timer in Hours with two decimals.
When I use the calculation (hours=seconds/36)
So I want to keep the calculation outside the timer interrupt and put it into the main Program.
But it gives me only random ...

Hi I have written a quite complex program for temperature control and energy saving.
The problem I have Is this.
Suddenly the Displays light goes off and the program hangs. (display light intensity is controlled by an Interrupt, with a software pwm)
I have enabled watchdog timer. I have only one ...

Hi
Thanks for the reply.
I just wonder why I did not find this thread when I was searching for error 120.
I already rebooted my Mac and it did not help.
I realised with an Apple computer using parallels a reboot of the computer does not reboot Windows.
After rebooting Windows alone instead of ...

Hi I have this issue with Flowcode 5.

Since today it refuses to compile any code.
I tried some old programs that compiled ok. which I never modified. And even those can not be compiled.
I get the following error message:


Launching the compiler...
C:\Program Files (x86)\Flowcode\v5\Tools\boostc ...

Hi Benj.
Thanks for the answer.
I understand your Idea this will work for changing colour, but how would you turn OFF both LED's at the same time?

Ok I see the option set duty cycle 10 Bit
But the Periosdregister still can have a maximum count of 255 which according to my knowledge is still eight ...

Hi what I actually was thinking of is Half bridge mode.
I guess this will not work because both pins will have the same duty cycle,
so probably it will be best to stick to the Software Pwm in the Code a posted in the beginning.

I have another question.
How do change the PWM to 10 bit mode?
The data ...

Hi Kernix
What I actually want is to change color not brightness.
So I alternate between read and green very fast at least 200 Hz and changing the duty cycle to have the color I want.
If Red is 90% then green is 10% If red is 50% green is 50% etc. If red is on green is off if green is on red is off ...

Hi Kernix
Thanks for your answer.
So I was certain this PWM was working.
The fault was on hardware. One of the vias was not connected, and therefore the Pic16F1825 did not have a proper ground.
So when the input to the ADC was 0 Volt it must have gotten ground through the ADC.
Since I fixed this ...

Hi.
I just wrote a program for using a Hardware PWM with also a software PWM
I get the strangest things with it.

If I use the software PWM only it works fine.
As soon as the Hardware PWM is enabled the software PWM becomes unstable.
I also have a ADC input on pin Number 7 for measuring voltage ...

Hi I am Talking about Flowcode5
Using a program in real Hardware.
A Pic 16F1939
My code is working now. I just want to learn More about variables.

Hi Benj
Thanks for the Info.
What I have noticed is that some calculations gave a return of 0 instead of the right result.
"A=(b*c)/d"

After I broke the calculation down into smaller ones

"A=b*c
A=a/d"

it works fine.

Hi I have a question about calculations.
Is it possible to use different variable Types in the same calculation?

C=A/B

Say the result "C" is bigger than 255 therefore it needs a Int variable.
"A" is a long number therefore it needs a Long variable and "B" is always less than 255 therefore it only ...

Hi Acestu
I find some things in your code that I do not understand.
First the macro tick is empty are you not using it anymore?
Secondly I do not understand what you want to do with the boost macro.
Are you checking if all the Timer Status variables are 0 ?
If that is what you want to do I guess ...

Hi
I have modified this code so that I can have a plain number.
Because I want to use the tempf variable in a calculation in order to switch a transistor.
I have used this code for several months now but somehow I suspect there is something wrong.
It seems that minus temperatures are not displayed ...

Hi Kersing
Thanks for the reply:
I renamed the files and it is now in english.

Hi Martin Thanks
I see the 19.6609MHz xtal gives some nice interrupt Frequencies and makes things easier.
I am using the Internal Oscillator at 32MHZ , the only Frequency I found that has no decimal point was 3125Hz. I realize it is slowing down the program unnecessarily.
Is there a simpler way to ...

Hi I downloaded the patch,
Now I can open the files from the forum.
Unfortunately flowcode is showing in German. I guess because I am using a german keyboard.
I trie to change the Language to Englisch, but I can not find the option for english in the drop down menu.

I can see German French Arabic ...

Hi I will try downloading the patch when it is convenient.
Our internet is very slow.
Is there a direct link to the patch?
If I want to do it from Flowcode Help.
Then I am forced to use windows to download it I would prefer to use the apple program. It is safer for me.

As for the flowcode5 programs ...

Hi I downloaded the Flowcode6 release version
Registration worke fine.
But Some files I downloaded from the forum do not open.

File name "20min.fcfx"

Error message.

"Failed to open document

I was downloading flowcode6 in the hope that I can use it to participate ...
