Hi Everyone...!
Sorry for my english, i am from Brazil and student of eletronics and computers.
I am try to work with AT89s52, but the uController do not response the downloader software .
The software and hardware that i am using is here: **broken link removed**
I try with the crystals: 110592MHz, 24MHz and others, but the chip do not response.
The software returns "0xFF" in the file that i save with name: "flash_89s52.txt", for the status of option "READ FLASH".
But when i try program the uController, its returns a error: Writer error at adress 000A byte written: D2 byte read:FF.
I tested the LPT1 port. I changed configurations in BIOS: EPP, SPP, ECP and ECP+EPP, i changed the uController ( it´s news ), but nothing works.
If someone that can help me, i am grateful..
Tnx
