#176335 - Help on AT89C52 programming |
Hi Everyone,
I have got four AT89C52 microcontrollers, and I want to use them, just for fun. So I want to build a binary clock, and I my problem is, that the datasheet says "8K Bytes of In-System Programmable Flash Memory", but I can't find any documents on how to program this controller, because I can't find pins like MOSI, MISO, SCK and others, like ther is on the AT89S52 which I used a year before, or there is also on AVR controllers. So what's the soultion for my problem? Can I program the controller through ALE/PROG and PSEN legs? Than what's the schematic and software for this? Thank you for your help. |
