Help My Project(12CH LED Driver)??

[Nandika]

Hi Friends,
I have some basic knowledge about MicroC.
I am coding for 12 channel LED drivr/flasher for Poson
I have MicroC and Protus for debug/coding it.

However,I have Little problems.
This is my 1^st

I want a command to MikroC for Manipulate each bit of Port.
Simply,
i want to turn on channel4 witch was connected to 3^rd bit/pin of PORTB.
I have tried before,But

My Try....And My MikroC About window

err1.jpg (99.34 KiB) Viewed 21867 times

I have also used this code.

Code: Select all

PORTB.F2

please,Give me a command or example for this.
Thanks

2^nd question is....

I want to add heder file like C++.
please,tel me how to add it and #include it.

Thans

[Nandika]

Friends,
It's OK
I could solve my problem.

Answer for 1^st question is,

Code: Select all

PORTX.Fn

X=PORTA,PORTB.....
n=pin/bit(0,1,2....)

Answer for 2^nd question is,
1.manually create .h file in project folder.
2.use add file in Project manager of MikroC.
3.code this(it's like C++ )

Code: Select all

#include filename.h

filename=manually created file name

However,Your help will want me for this Project.

I'm not discouraging you on Mikro C. But I should say HI-TECH C is very good for PIC, dsPIC programming. It is the only 3rd part C compiler recommended by Microchip. The main point I love about HI-TECH C is, it is very straightforward. MikroC has fancy libraries which make it looks like a very high level environment. I don't see any advantage in driving a say LCD with a library where we don't know what is happening inside. No fun when we don't know what is happening. Assembly is the best, but since time is also important C is the most suitable option.

Thank you ZevenZero,

I really know HI-TECH C is good.before,i worked with HI-TECH C.I created some small project using it.
But,Now i haven't HI-TECH C.I must download it feature.
Actually,I can understand that you said.I'm a beginner for PIC.therefore,I must use Assembly like languages.It is advice for understand reality of Micro controller.
Till,I download HI-TECH C,please help me for Mikro C.(I never discourage )

Now,I have some big problem.I want to adjust Time delay in code.Now,it's constant.like this,

Code: Select all

Delay_ms(500)

I want to add Variable resistor for adjust it.
I used PIC16F877A.PORTB,C,D ware dedicated to LED channels.
I have PORTA for connect VR.

Please,give me example code or learning source for do this.
thanks

There are two methods to do this.
1. Saw tooth method , with a op-amp and count duty cycle. [analog jam , I love this believe me,I could help you
on this].
2. ADC way.

Choose the first method if your micro does not contain a ADC unit.
Which way you prefer.

[Nandika]

Thanks SemiconductorCat,
I like to learn both.
But,Now,I like to use 2^nd one.because,i think,it's easy for this time.
My micro is PIC16F877A.it has ADC unit.
First, tell me ADC Way

After,if you can,if you have time, tell me OP-AMP,saw tooth method.really,i like it.because,i am also learning about OP-AMP.

[SemiconductorCat]

There is a example here :
http://www.mikroe.com/download/eng/docu ... ibrary.htm

as it sounds the first two methods is by using ADC.
and last one uses internal RC jam.

[Nandika]

Nice.. Thank you SemiconductorCat,
I already have it in MiKroC user manual.I forgot that.
ADC system is easy,But, .We can't get more idea from it.

If u can Please,explain your OP-AMP system.
not now..
