content: So for years, I've used a PG302 from Iguana labs to program some chips. My programmer finally seems to have died and I can't get it to work.I bought a cheap programmer from aliexpress and can't figure out what to do with it. It came with no documentation at all.The programmer is and ep51https://www.amazon.com/Microcontroller-Programmer-Ep51-Burn-AT89/dp/B00A1OLLPI/ref=cm_cr_arp_d_product_top?ie=UTF8Can someone please help me figure out how to use this thing. I've tried numerous different softwares and none of them will communicate with the programmer.I tried to use Keil, but it doesn't seem to want to work either.Does anyone have any idea how to use this thing? I'm feeling pretty bad about myself right now for not being able to figure this out.

content: Those boards are designed for the STC Chinese 8051 series parts that have the built in serial bootloader and AFAIK they are not Atmel part compatible. For the older Atmel chips, I use the cheap SP200 series of programmers.https://www.amazon.com/EEPROM-Programmer-SP200SE-Enhanced-Version/dp/B07P3HMD2Y/ref=sr_1_13_sspaOf course the TL866II is probably a far more versatile choice but if you want to do it on the cheap, the SP200 can’t be beat.

content: I found your post while I was looking for a solution to my problem. I have got an old at89c2051 programmer that recently turned its toes up... Sounds familiar??Recently, I purchased a pretty much identical programmer (some clone from Ali Express) to what you bought. It is in a kit form, and much to my disappointment there were no instructions whatsoever included with it. The only clue I found was a small piece of paper with a website address (www.56dz.com/pcb/show/1176.html) from which I managed to download some incomplete programming software. I found missing dll files elsewhere, got the software up and running. It is in Chinese (LOL), but it looks very simple. It allows to read and write hex files, erase and set lock bits.If you're interested at all, I would be happy to zip it and send you what I have, including some other pieces of info I found on Internet.At the same time, I was quietly hoping you might be able to help me. I can't assemble my kit unless I know what parts go where.Would you be able to send me some closeup pictures of your device? I'm after the placements of resistors, there are about 10 of them, if I can read the color code what would (probably) solve my problem. Also, there are 3 transistors, my kit has got 2 NPN and 1 PNP transistor. They are some generic brand, small signal. Would you be able to read what's stamped on your transistors?You can contact me directly on my email if you like.petersych@hotmail.comWarm Regards from Melbourne,Peter
