Using ADC n PWM to light up the LED dimmer - need help

i am doing ADC

I thought it was due last Monday.

I suggest you stop wasting your time online and start studying C

Which part of the code are you having trouble with?

Re: i am doing ADC

cos i quite urgent so i need u to tell mi the code is doing what. den from there i will slowly learn by myself

Added after 5 minutes:

i dunno the code is doing what.. jus tell mi first, can?

How's the studying going? The code is commented so it's not to tough to figure out.

Hint: The {} indicate a block of code.

PS "me" is not spelled "mi"

Don't they have electronic forums in Japan?

Re: i am doing ADC

jus tell mi the code tis code meaning unsigned int index=0, total_period= (unsigned int) 255*256, on_time=0; mean what? i dunno what is the meaning. is urgent

That line sets up your variable types and initial values
index = 0
total_period = 65280
on_time = 0

Re: i am doing ADC

can give more detail? explain more pls.. i really lousy in programming de

It's a single line of a program. It's a declaration and tells the compiler the variable type and initial value.

You can download free C compilers for your computer and try out programming in C for free.

I posted two links. What didn't you understand?

Dont pay attention to the UNIX.

Re: i am doing ADC

what is that UNIX mean?

 

[blueroomelectronics]

i am doing ADC

UNIX is a commercial operating system it's similar to Linux.

Re: i am doing ADC

now my ADC code can read the value but the PWM i have no idea hw to test n do the coding.. any guide? or help mi

 

[zj3515]

i am doing ADC

u can measure the wave duty of the PWM's output pin of the C8051.compare with your setting of PWM register

 

[jason1987]

Re: i am doing ADC

the problem is i don't even know how to measure the duty cycle and how to write the code. i need some guide

Re: i am doing ADC

use oscillograph to mesuear.you must read datasheet and then write code.
