I just wish flowcode had an option to change comment color would be nice for bigger codes sections like for me when youve just added a comment a small star comes next to it on the left with a red Dot in the middle would be nice if you could click on that star and then opens up small boxes of colors ...

My charger code works really well am now going to build its transformer and control it's primary tapings for low and high charge.Just for my small battery connected on my alarm i coded in flowcode too here bads guys like taking what they have not worked for at night so i designed an alarm in flowcod...

Is using hex numbers instead of decimals reduce code size? Coz all my code has fit in well into the 16F88 now.

It's all your hard work Martin i wouldn't have done it without your help i was broken down back then you remember? not until you came in and opened my eyes thanks allot I also wanted to see the simulation work too as you said but if you have allot on you this is already enough thanks a million times.

Thanks allot Martin for all the info for which I've been able to come up with some words on the 7seg that am going to use in my simple 17Ah battery charger,these words will be flashed on and off together with the current battery voltage in an interval of 5 seconds for each that is (word and voltage)...

Just finding the numbers needed to display like 0,1,2 upto 9 and Boom just look at the resultant number generated for a used port so that someone does not need to calculate anything just look for the number u need to display and you are good to go,Martin this is so good you have simplified the 7seg ...

You said you can make the simulation possible too Martin before i do the update i would love to see this too as i can learn something from it never know coz finally Tes5b turned out to be interesting though i had to remove the switch with the red Dot and replaced it with a new one and also removed t...

Was going thru your Test5b but haha calculating each number from 0-9 to choose from based on the switch MPXstate number was a very nice interesting trick Martin what i still don't understand was the red Dot and what it does but theoretically I've got what the numbers mean very Bright trick there.

Was the common anode 7seg safe as all the output is low to activate the common? Just asking as this question won't be useful after Benj's update

Ok cool as i was going through your replies I found out that you had already answered my question as to why it didn't work out in the first place, thanks to Benj if he corrected that hope it will help many people out there who will need to use the 7seg display and not to go through the hardships we ...

No i will have more questions just because I've been busy with house work haven't really got to look into the code but i put up a question for you check above before your recent reply other questions will come in after I go through Test5b.Thanks for the good heart to teach Martin.

Thanks for the chip 16F1847 i need to find it but will have to order it from China can't get it here in Uganda .

But to study this well i need to get to the bottom side of it and know why all the other way that i had planned it before you came in didn't workout what was really the problem coz for you to see this you first tricked it with a 123 in one sec then u realized the problem what was it is a good questi...

I have used only 5a so far but I've changed it a little and it's working fine i removed Timer0 and it's count and transferred TmrMultiplex macro to be called into Timer2 interrupt and i set the interrupt frequency to 200 Hz and it's working well. With fairly reduced half lit LEDs am going to study 5...

This is so cool i think it's time for me to learn about the numbers in TmrMultiplex macro of Test5b if you have some more time Mr Martin.

This conversation is not over yet Martin don't even think for a second that it's over there is allot to learn from you the numbers in Test5b are troubling my head need to know what they mean but even i don't know how to thank you coz you have delivered me from the worst nightmare

Am going to go with Test5a tho Test5B works best it has no half lit LEDs and the decimaal on leg3 is now gone after your changes to clear B7 but it's complicated LEDs are lit very well but for Test5a if you look at seg1 and seg2 for example when it is displaying 12.2v there some LEDs that are slight...

I think I will have to go with Test5a coz Test5b looks complicated tho I want to learn this is completely off the map I've lost track need to learn this.

And I very much want to learn the tricks you used don't understand the numbers in TmrMultiplex switch what they actually mean and another thing there is no seg3 in TmrMultiplex macro yet the code works even for seg3 how did u do this?

Test5b also displays a decimal point on seg3 which it shouldn't be but anyways I can go with Test5a but my question is coz I have to make another pcb with a bigger chip like the 16F886 for all my code to fit in there question is will have to do the same in 16F886 or there is something to change?

Am done with Test5b it also works but the 3 on seg3 is half way lit it looks like a bracket ].

I first tested with voltage = 1.22 the i removed that calculation as i was most interested in the ADC so yes that is 12.2v as for my batery it all worked well am now testing Test5b.

Ok test5a has worked going to test5b now
