vusb programmer #1

Thanks for a nice programmer using attiny 85. I loved this tiny programmer and using it. Just curious, is it possible to use this programmer to program AT89S51/52? If it can be, what changes are required to use it as a 89S5X programmer?

It's almost 10 years since I created the project and at least 5+ years since I worked on an AVR mcu. I am mostly onto msp430 micro-controllers now, so I am not able to help you.

My understanding is that the programmer project do reply on a very specific 16.5Mhz clock option that the ATTiny provides. So it is not very likely that you will be able to duplicate the project on an AT89 chip.

Hi, Thanks for your reply. I think my question confused you. I want to use this attiny85 based programmer to load hex file to 89S52 microcontroller.
