[SOLVED] how to merge two adc codes to one code for same mcu

[Muhammad.Saad]

hi
I just want to know how to manage two different codes to one code, as i have one code for digital voltmeter and second for voltage limits. but I want to make both of them working on same controller. the code is pasted below:

Why do you want to merge the codes? The second code uses 7 Segment display to display ADC value. The first code is written by me.

 

[Muhammad.Saad]

thanks milan your code really helped me.
I want to use these codes for a same mcu. when voltage on 7segment is higher than 4.5 volts first led should on, and when voltage is less than 1.5 volts second led should on. I am also attaching proteus file plz check it. actually I want to make over under voltage limits for digital voltmeter. looking for help.

 

[milan.rajik]

Zip and post your mikroC project files. I will edit and post the modified code.

 

[Muhammad.Saad]

here are project files

 

[milan.rajik]

You need to use Transistors (BC547) to drive the enable/disable pin of SSD. You will need 3 BC547s.

 

[Muhammad.Saad]

did you get the code? and plz also make modifications in proteus file.
looking to hear from you soon. thanks milan

 

[milan.rajik]

The file you posted doesn't contain complete mikroC Project files. Zip and post complete mikroC files. Mention what SSD are you using, CC or CA type? What is the range of voltage you want to measure?

 

[Muhammad.Saad]

SSD i am using is CA. the range of voltage i want to measure is from 0 to 5 volts as shown in proteus file. but i want to add one more feature , i.e voltage limitation.
When voltage value which is displaying on ssd is less than 1.5 volt the led which is connected with port D pin o should on.
When voltage value which is displaying on ssd is higher than 4.5 volt the led which is connected with port D pin 4 should on.

i have codes for both (ssd and voltage limiatation) but i want to make one project file, actually i want to merge two codes in one mikroc project
i am sending the complete project but i couldn't add tthe feature of voltage limitation which is mentioned above

 

[milan.rajik]

Working project attached. See sim.avi video inside .rar file. I have used Proteus 8.1 SP1. If you have older version of Proteus then redraw the circuit in that version.

When voltage value which is displaying on ssd is less than 1.5 volt the led which is connected with port D pin o should on.
When voltage value which is displaying on ssd is higher than 4.5 volt the led which is connected with port D pin 4 should on.

There is no PORTD in PIC16F873A. I have used PORTC instead.
