Thanks bro. I'll be test this one. Problem solving for pc without paralel  and serial port.

Response by Joy on 10/13/2009 6:59:50 AM

I've made the usbasp programmer according to the site "http://www.fischl.de/usbasp/"

& it is working pretty fine ..

But i couldn't understand what to do to make it program at89** series controllers ..

Please reply .. I really need it ..!

Response by Son2Labs on 10/13/2009 7:01:39 AM

Oh no.. in chinesse language.. pls.. anyone can help me for translate this project into english??

Response by azariah on 10/13/2009 6:58:02 PM

hi thank u overmuch i try this programmer i have to no what is (SV 1)
plz tell to me

Response by Joy on 10/13/2009 7:48:20 PM

r we supposed to use this softearw only ??
actually i've made my gui for avr controllers ..
after programming the atmega8 with the new hex , can i use avrdude to program at89** controllers ??

Response by Joy on 10/13/2009 8:11:17 PM

r we supposed to use this software only ??
actually i've made my own gui for avr controllers .. after reprograming atmega8 , can i use avrdude to flash at89** controllers ??

hi sir i con under stand the SV 1 sir will u explain sir

Response by weijie on 10/17/2009 8:30:59 PM

this meaning that we must at least have a ATmega8 microC programmer ? How to connect the ATmega8 chip with 89S ISP lines ?

Response by Ravi Kant on 10/20/2009 11:15:24 PM

I am trying to build ISP programmer using serial port, and I am using tantalum capacitors 1uf, the programmer  is not responding , and sometimes it responds, also when it responds, the message is programme enable failed.


Kindly help for the same.

Response by Ravi Kant on 10/22/2009 12:44:51 AM

Hi
Binu

I want to know wat are these J1,J2 and J3 for.

Kindly reply for the same,

Thanks in advance

Response by weijie on 10/22/2009 4:36:09 AM

this meaning that we need to have a AVR programmer first before can make this AT89S programmer ?

Response by dev on 10/24/2009 8:51:42 PM

programmer idea wanted for 89cxx AND 89sxx

Response by Ravi Kant on 10/27/2009 6:47:56 AM

Hi

Binu

I have Atmega8L, so is it different from Atmega8

Response by Joy on 11/6/2009 1:10:17 AM

yes atmega8L will not work at 12 Mhz ..

Response by Abhinav Jain on 11/10/2009 7:01:41 AM

hello sir
will u please tell me  
is it working or not for at89s52/51

Response by Pertamax on 11/16/2009 3:57:23 AM

Hi Binu,
May you explain more detail how to setting and operate Progisp...

thx

Response by Abhinav on 11/18/2009 7:59:21 AM

Hi joy can you please let me know which file you have downloaded from http://www.fischl.de/usbasp/. there are a lots of option and i am a bit confused.

Response by kapil on 11/18/2009 7:13:30 PM

Hi good work!

I have a quarry that I have already a USBASP and what I can directly used for the 8051 programming.
I not then what modification is required? is there is only change in firmware or the whole circuitry is changed>

what modification you done in the firmware ?
what is fuse byte for the the ATMEGA8 for 12MHz crystal/
thank you.

Response by kapil on 11/18/2009 7:19:13 PM

I have a suggestion that you improve your software as i can be easily used.
In your software there is a lot of check box and selection is there.
I can help you to improve your software.

( Please look "extreme burner" for avr programming it is a good tool for beginner and you also develop such type of programmer tool) even i am open for your help.
thanks for your time
kapil

Response by Kapeel on 11/27/2009 11:20:34 PM

If Kapil is sugestsiong to simplify ProgISP, the sugession is not valid for BINU. Coz the software is devloped by a chineese firm "www.zhifengsoft.com' But anyway.i am personally using the software since more than 4 versions by now.

Response by Kapeel on 11/27/2009 11:25:57 PM

By the way..in case anyone is intretsed in similar programmer, one may have a look at www.united77.com/keeprog.htm who has a programmer which will program all AVr's and 89Sxx chips which is supplied with Prog ISP. I am using the same since 4 months without any problems. Its really a worth buy for just 500/-Rupees

Response by Sajid on 1/9/2010 7:11:16 AM

Hi,

I just want to confirm. Is this hardware (the circuit) identical to the fiscle's USBASP? i.e., can I just reflash the atmega8 of my existing USBASP to add support of at89s52?

Response by Sajid on 1/9/2010 7:34:02 AM

and one more thing,

After flashing your firmware, is the programmer still called a USBASP in avrdude?

Response by Abhijeet on 1/13/2010 6:22:25 AM

Hello Binu...

i have a USBASP Programmers mentioned in the website
http://www.fischl.de/usbasp/

i programmed a new Atmega8 IC with main.hex in the USB51 firmware u have mentioned
and wen i replace the original ATmega8 IC From the programmer with the new programmed IC...
The usb isnt recognized...
can u plz tell me a solution for this...
im new with atmegaIC's... dunno about FuseBytes...

pls tell me a solution for this...
i have Windows XP...the working programmer programs ATmega8 ic successfully...dunno wat is wrong...

Response by raj on 1/14/2010 8:51:14 AM

hi, i have the same problem mentioned above.please reply.......want a solution.

Response by Smitha on 1/16/2010 11:44:19 PM

hi,

i am using atmega 16 and want to programm it through usb programmer.i have brought atmega8 and done the connections shown in the ckt but it is not yet programmed(atmega8). i have connected the atmega8 through usb port to the computer. it is then asking for Driver. but i am not able to find the setup of the Driver. can u plz tell me how to install the driver and where i can find the driver setup?

Response by Abhijeet on 1/17/2010 10:01:27 AM

@smitha

The Atmega8 u r using in ur USB Programmer, is it already programmed by the given firmware...
if yes...then it must be getting recognised as USBasp on ur PC..and then simply upload the driver from the directory where u have downloaded it...
here is the link to download the driver...
www.fischl.de/.../usbasp-windriver.2009-02-28.zip

or goto http://www.fischl.de/usbasp/
and download the driver, its given there...

and if the ATmega8 is not programmed..then u have to program it externally with some another AVR programmer with the given firmware...then u can use it as USB Programmer...

Regards
Abhijeet

Response by Nitin on 1/20/2010 3:07:17 AM

hi binu sir,
i have built the circuit and using progisp software.
but i am not able to program my AT89S52 chip.
i get the "Program Enable Error"
please clarify me the solution of this problem

Response by lukcy on 1/22/2010 3:14:23 AM

can u make a tutorial (ex:video) for using usbasp for at89xx

Response by Nitin on 1/22/2010 6:09:00 AM

@kapeel
i hav already tested keeprog mk2 bt i mgetting the error of
"chip enable program error"
is there any reason of error if i use 11.0592 MHz crystal than 4 MHz as shown in figure above...
please reply me ASAP..
i m stuck in the middle of a project..

Response by Pamkin on 1/28/2010 12:04:36 AM

Hello Sir Binu! Let me talk about steps install program usb ^^ ( my option, if it's wrong plz you correct it )
1.Program 89Sxx: first progam atmega8 then add 89Sxx into socket then program.
2.Program IC another: take out 89Sxx and run program progisp.exe.
Is this circuit program include atmega8 for 89Sxx?
3.If i don't want program 89Sxx, is this circuit program IC in list of software? So what program ATmega for support 89Sxx? is this file main.hex in usb51 folder?
Thank for read!

Response by Karan on 2/5/2010 1:56:14 AM

Hello,

I want to make above Programmer for  AT89SXX.

But I am zero in AVR Microcontroller and Programming.

Can I solder this circuit and  program the main.hex into an atmega8?

For program ATMEGA8 with Traditional Serial ISP Programmer?

Thanks

Response by Mostafa on 2/9/2010 11:49:11 AM

thank you for your programmer.
I have made your suggested circuit and I have programed ATMEGA8 with main.hex from your package. but like others when I connect the usb port to the computer only the red LED turning on but the usb is not recognized (I only changed fuse bit for external crystal and other fuse bits like lock, watchdog are not seted) another point is that I have disabled serial programming for ATMEGA for MOSI, MISO and SCK ports. please help me

Response by Mostafa on 2/9/2010 12:53:41 PM

I found the problem, only one of my laptop usb ports can recognize device.
but for programming I should read micro (for 89S52) to erase or read the signature, but when I want to program, "enable error" message is displayed.
please help
