Hello
Im starting to learn how to program AT89S52 and i was wondering can some one give me a simple charts to build a programmer for my self
a have USBasp cable and i wish to use it for my programing
if some one can give me good advice im happy to read it
i dont see your upload
im looking for way to connect the USBasp whit the AT89S52
i had some problems whit connecting the USBasp to my Laptop but i fix it
i try this https://www.thierry-lequeu.fr/data/ISP-USB-5.jpg
but i get error on reading the microcontroller ( i used Resistors too )
IF you use a usb based programmer you need a pre programmed controller before you making your programmer
Other wise you can make programmer to burn controller(8051) through direct parallel port
and available the circuits in web
Congrats on your success.. I too need the exact way how to program AT89S52 using the same USBASP..
I referred the image you posted.. Do I need to connect the programmer, as it is in the image?? Were there any modifications you made??
I didn't understand what's "used 20 SJK instead of SJK 8 now everything work"??? Which frequency crystal oscillator did you use and are the capacitors 30pF only??
