Hi Harsh Pandya

 

Your answer so right i put 10K pull up resistance and it’s worked good… Thanks Pro.

 

And another discussion in this link if any one need more information.

If we can see example about this it will be great for us to calculate our HEX file.

Thanks dagakshay

Finaly I Complet my project with perfect measurement 8-Channal…

my friend ROMEL…

I found the ansower about random measurment of the ADC0808 that when we put a simple channal we must comman the ground with the ADC0808 (SINGLE ENDED Tying) i make the hardware & software with VB6 and it’s work with 8-chanal perfect.

 

MR.DAGAKSHAY

thanks to your help and for this site when i provide my project i wrote in the reference URL site of Engineersgarage so i’m greatful so math

lol

my freind Salman i mean interface a USB cam with microcontroller not with PC

Greeting to all

Hi every body…

Can i interface a webcom camera with USB port? if not what are kinds of the camera that can i use with???

This is the Code Romel

the delay function can i calculate the time delay by using ((1/11.0592*10^6)*80000)??

or ther is another way to calculate???

Hi dagakshay

 

Thank you very match nice teachnic. is this called shift the writing???

 

Thank you again

[Ahmed]

Hi dagakshay..

 

Atmega32 have only 4 ports like ATMEL C51 if i want to interface 6 7*5 dot matrix leds how can i provide external ports ????

I think you can interface just 3 dot matrix leds is that right or not ????

 

can we use another way to do this with one chip? and how ???

[Ahmed]

Hi Romel.

yes they are right just with win XP.

But i found crack that make the program work with 7 correctly

 

Her it is my friend

With Greads

[Ahmed]

Hi Romel.

I thing my previuse design the Vref was not correct but i remomber i check it with DC voltmetor it gives me 5 V and the IN0 determined the voltage correct but the oather going wrong, some times the software pass in errer however i repeat the design in case….

 

my fraiend i use Proteuse version 7.6 SP0 Pro with crack on win 7…

if you need me to upload it just tell me & i will this to y

 

Good Luck

Hi Romel

my friend after trying to solve the problem I asked my self what happend if i repeat the ADC0808 connection with the microcontrollor???

so i do it and don’t know how the procedure going well and give me exact result….

 

 

check this out and give me the report

Hi There

I have the same problem whene i put 8-chanal the chanal read random value????

But i found same project in the net with DC motor but give me the real result but don’t know how!!!????

i but my program in the net simulation (meains DC motot microcontroller) and give my exact resalt…..

 

this is the 2 proteus simulation MAIN(my simulation) & NET simulatin

 

REAPLY US if any one knows the problem…..

 Hi DAGAKSHAY

 

I promise to upload a video of my project….

 

this is it
