ISP Programing on AT89S51.

10/23/2010 1:25 AM

I am a new to MCU and want to program(ISP) my AT89S51 IC using simple Parallel cable connected with my MCU on Pins (p1.5,p1.6,p1.7 and and Reset). I can read the Data from my MCU but unable to write data (Program) to MCU. When I try to read data software shows an error ("Unable to write at 00000H, 174 byte write" or something like this). I have tried different software but same error occurs. Please guide me the correct methode

Acronyms should be defined on their first use. What is an MCU.

You should refrain from their use PDQ or ASAP!
