@tapu:
My suggestion: try to use a better 5V power supply with decoupling capacities (as close as possible to the RTC).
The DS1307 is very sensitive to the quality of its power supply.
Re: Ds3231 RTC: temperature display (mikroC)
Yes, because my post above is a (well-functioning) solution, not a question. I just wanted to help others, so I published it.
Kind mods, please move this to the right place (I couldn't find any better). Thank you.

On request I wrote a simple and fast function to display the temperature
measured by the Ds3231 internal sensor.
- no any floating operation (integer arithmetic only)
- no any character buffer (each digit is displayed immediately after computed)
From the Ds3231 datasheet:
Temperature is...
As I see this is a hard, very big but nice job. Thanks!
Unfortunately, I don't have the time to watch long videos, but I know they may be useful.
It would be good to see the whole project with the source files (in a RAR).
Kind regards:

PS:
I gave you some points on the board (as a thank you)
Hi dahmano;
I wrote such VU meter programs but in mikroC, not in mikroBasic. You can find them here, on the forum ...
However, long ago I wrote VU programs using the Proton Basic (PDS).
Now I upload (only for you :wink:) two versions.
I'm using the Proton Basic also now, but only as a very...
This is an almost impossible "mission", the input pulse is too short.
And ..you know the usual rule:
the transistor (used as a fast switch) should not be driven into the saturation range ...
Hi Garyl;
I advise you to try it in reality. I've readed this somewhere:
In Proteus the T0CON.TMR0ON bit works incorrectly in counter mode (ie if T0CON.T0CS = 1),
but it's working in timer mode (T0CON.T0CS = 0).
Tried also by me, it's true.
My rearranged (and repaired) initialization:
//...
Attached the expanded and improved version 2.1
What's new ..
- Two new projects:
-- the 'one-line' stereo VU meter, in the "ONELINE" folder (see my post #2)
-- On request a 2x10 LED version, in the "16F88_2x10led" folder.
- Fixes:
-- The displaying of the text "lin/log" on the upper LCD...
Hi Andy;
I do not know if it can be, but maybe that will help a little:

Using this you can see and also print the lay6 file.
Hi mcmsat13;
Do you know that the PIC16F628A does not have AD converter but only two analog comparators?
Please study its datasheet.
However, the PIC12F683 has a 4-channel 10-bit AD converter.

Hi schmitt trigger!
I think you are more of an 'analogue' man (nomen est omen ;-)). For a long time I was also like you, too ...
Thank you for your kind words.
Welcome to the club (although I am only 73 years old :lol:).
At this time I also built a VU meter, first with discrete transistors, but...
