GreenBee Project

@Sir Majoka,
Sir, i do have a question about this link,http://www.8052.com/users/AT89S52InSystemProg/,it says in there that i must burn the firmware into an AT89C2051 and i will need a conventional parallel Programmer to Program it). This parallel programmer involves another circuit sir?And do i need another programmer software which is different from the AT89SXX ISP Flash Programmer Software to burn this so called firmware?
And i also consider this simple programmer which i got from one of the links you have provided. http://chaokhun.kmitl.ac.th/~kswichit/tahan/boards51/Board%20S51.htm. Could i use this sir for making the greenbee project?
Thanks for the future response about this matter sir!Sorry for the series of long questions ..
More Power to you sir majoka!

http://chaokhun.kmitl.ac.th/~kswichit/tahan/boards51/Board%20S51.htm

this is a test board for initial stage u can also make it but u need as well as programmer that is also in the link that is of parallel port

http://www.8052.com/users/AT89S52InSystemProg/

in this circuit AT89C2051 is used u need a programmer for that i suppose that u has programmer in university by using that u burn and after that it will burn the other chips

I think its easier to use AVR controler like ATmega8 for this project.
Even the programmer is easy to make.

@ firoz3321
PIC ,AVR or any brand that is available in local market that can be used
AVR are costly so less people use that

but ATmega8 has internal ADC too so it solves many connection issues. Because i have done GreenBee i see it easy on AVR than on 89C , also the cost is approx 80 INR variation.

at the time of my project i was not aware of the ATmega8, but now i have done a few on this so i feel we can easily have the programmers too.

i completely relied on my college KITS for programming , because i didnt have the programmer with me then.

@ firoz3321
yes AVR programmers are small in size and AVR are fast controllers
PIC can also be used it also has internal adc as well as other peripherals as AVR has

I personally never worked on PIC

@ firoz3321
if u worked on AVR then it means u worked on PIC
all controllers logically are same logic is same almost timer, counters are same

I wrote the following code from scratch for AVR controller last night.
I knw its still incomplete, can someone please let me knw WHAT am I missing ?
Does this code even work ?

I am a beginner and not good with coding, but just wrote this for time pass. please suggest the MISSING PARTS. and MISTAKES in the code SO FAR

@ firoz3321
is it working and u want to ask for improvement in coding or ur getting error or problem in that sense u want to ask
