Failed to compile reason being there is a missing componet: IsSim1::Check and one question what is the red dot next to the switch in macro TmrMultiplex for?

Copy that sir i will be waiting thanks for all the efforts GOD BLESS you.

How in the world did you do this Martin!! It works as you command it to this has been a one time nightmare for me.

Ok your Test 3 was flashing solid clear 123 at an interval of one second on seg0 and seg2 check the attachment

While I was building my pcb this is how I noted it's pins as in the image below this is in my note book.

Yes it must be hardware or chip haven't done all the test am going to do test number two now.The 7seg part number is as it appears on the image below it's a common cathode i got from China but i followed all it's letters and commons and they were matching the standards before i put it on my pcb.I do...

After forcing the output voltage to be 1.23v as you requested i got a funny display as you can see below.

Here is the one sec Tester.

An3, yes i did and there was 1 volt with that one volt was supposed to give me around 12v output on the 7seg but it shows clear flicker zeros and changes to some numbers like like 549 with decimal points on seg2 and seg3 in all the code i never activated decimal point on seg3.And i also did the one ...

Martin you are not going to believe what am seeing when i was doing the one sec test.Check out all the attachments, in the code i decided to display a 0 and a 1 on Digit0 only in an interval of one sec to work as on and off but to my surprise on the real boad two Digits were lit that is Digit1 and D...

On measuring the An3 pin zenner with the Peak Atlas Zen50 tester i got 5.18 zenner volt @ 2ma , 5.19v @ 5ma , 5.20v @ 10ma and 5.21v @ 15ma my question , is this zenner fit for my An3 pin with the extra 0.21v at highest?

An3, yes i did and there was 1 volt with that one volt was supposed to give me around 12v output on the 7seg but it shows clear flicker zeros and changes to some numbers like like 549 with decimal points on seg2 and seg3 in all the code i never activated decimal point on seg3 right now am going to t...

Wawo! thanks Martin i can see you are trying had to make me understand as any very good teacher who loves his job would do and i believe this information you provide is helping other people in the windows of this chat ,to some extent now am beginning to like things that fail to work out in the first...

Am i supposed to build the 1 one second flasher led on a real board or even doing it within flowcode is ok?

Ok let me do that now but you talked about my 3D scaling that it's not right how do i correct it?

Thanks Martin for all the effort to help me out of this nightmare i think it's not flowcode problem there is something am not doing right first for 8mhz what should the OSCCON value be? Looking at the 1 second i got this have a look at the attachment.

Don't know if its a bag in flowcode v8. ok i did what you told me first to put the ADC read into main and this time this one worked really well with no display flicker at-all but sending to the hardware still doesn't work maybe you can try it for me on your hardware you used last time and see the ou...

Ok the code was too big to fit in the 16F88 so i had to remove all the voltage calibration lines and the battery Volt cut lines to make it fit in my current chip.So the remaining code is for displaying voltage on the 7seg only.But when i loaded it in, it only displays zeros yet in simulation it work...

Hi Martin thanks for your advise of the stop watch example,sorry for the delay reply coz i was abit disappointed with my 7seg so i didn't work on your example at first until this covid19 lock down that i gave it a second thought.When i was going thru the stop watch example it seemed very interesting...

Steve001 i dont want to know about charging my battery what i need is a battery charger circuit code that is working for my deep cycle 17Ah battery or to fix my 7 seg circuit.

"I have produced flowcharts that drives 7seg displays just fine, so if you are not getting one to work or chage your mind, In will sort the display out for you." That will be so nice Martin, i really love to learn this 7 segment in flowcode but of all things am learning this has caused more trouble...

You know Martin i Respect you so much but I've given up on this particular project if you have a better charger that uses may be PWM or any other good methods please help with the flowchat then i will make another circuit for it but I've had enough stress with this particular project more so with th...

Ok LeighM just did your config and i think its the same way recommended in the datasheet of most MCUs to use 10K but as u can see i got the same results as before.Measured 12v battery with 13 volts on it says the multi meter but this one showed me only 8.90.v, ok i always calibrate the voltage to ma...

Ok LeighM i will also try that and see the out-come tho i've been using that same config in quiet a number of circuits with a division factor of 11 and it has been making wonders measuring voltages accurately compared with good multi meters.because i prefer dealing with the noise than dealing with c...

Hi LeighM here is my PCB image its in PDF any help for this circuit to work as required is highly welcome and also if anyone has a better charger code maybe by use of pulse width control will also be of an added advantage.
