Hi,

Thank you very much for your reply.

I read your reply and understood how to do it. Your step by step information really helped very much.
I'm going to use 16F88 as a replacement for 16F84. Then I can use it without changing my old circuits.

Also I checked about circuit and going to add that ...

Hi,

I tried to add a new topic on V5 forum. But I can't add one. That's why I posted this here. Sorry for that.

Anyway I want to get some help.
I mostly use Flowcode for make light designs. I want to know how to add a potentiometer to the IC to control the speed of lights.

I have V5 and I'm using ...

Thanks Mr. Benj and Mr. Martin.....
Today is my that day... yesterday i tried many many times to solve my problem and in the afternoon i thought to make my own decision.. So......i thought another long way (or somtimes short :D ) to make my LED Countdown Clock for today...then i used 2 16F877A PICs ...

Thanks for your reply..
I tried both...(if tick>122 and if tick<122). But that program doesn't work in Proteus or in the Circuit..i uploaded videos of all of it in circuit, in Proteus and my FC4....
What is the wrong with this...if you can please help me to solve it..
Video file is about 6Mb. so i ...

Thanks for reply..
I made your program with Flowcode v4. Program is correct as yours. But it did not work correctly in Proteus or the circuit..
Is Flowcode v5 and v4 are different? Because your v5 program works high speed in v5 (if tik<122). But in v4 it does not work with that speed.
I download v5 ...

Thanks for your reply...
This is the Proteus file and a pic of my circuit. I used 4MHz Crystal..
If you can please help me with this....because I'm stuck with this now...

I'm making a LED Countdown Clock for my schools' science day..
I used 16F877A pic and 6 common cathode 7segment displays for hour, min and sec for programming.
I used LEDs for make 7segments in circuit. The program works fine in Flowcode v4. But in the circuit LEDs does not turn on.
When program ...

Thanks Mr.Benj.
I will try to correct it....

Thanks for your information.
I made a light running circuit using 16F877A, 4MHz crystal with 22pFs. Circuit works correctly. But lights running speed is very very high. I cant see my designs.
I took RB0-RB6 and RC0-RC6 as outputs for lights. I changed FlowCode program options > clock speed to ...

Thanks again...
Now I'm trying to understand it..
Also can you help me in the future in my programming problems?
Thanks.

First thank u Mr. Martin for reply me..
I'm new for FlowCode. Also I'm still learning about PICs. I'm using FlowCode v4..
I'm making a 14 way LED running program with 16F877A for Vesak festival in Sri Lanka..
I will send you my original program tomorrow. Now i have a little design of it.
If you can ...

I want to dim LEDs or other lights..I mean like the LED light going down & coming up again. But I don't know how to do that. Please help me for it..
Also I want to know how to turn on 2PORTs at one time. Like 16F877A PORT C0 & PORT D0..Please help me how to do it in FlowCode...
Thanks..
