I have made a circuit with a 27256 eprom in proteus 6.3 & SP1.
eprom settings: Vpp to +5V, /OE and /CE both to GND, didn't change the Advanced Propeties.
The image file is a BIN file, start address is 0x000 and when I use Debug the memory contents is OK.
The address lines A0..A2 are connected to a counter 74LS90 with a clock of 3.6kHz. (...)

I didn't see your ckt becuase i havn't proteus V6.3 (i only have V6.2 SP5)
I redraw the circuit from your c code.
I uploaded the DSN file.
Your orginal c code don't need any change.

I wanted to use a 27c256 eprom as a binary to bcd converter. Basically the 16 bit binar number is the address while a 8 bit bcd in the output. Simple enough. But I don't know how to produce a bin or hex file which would load the wanted data in the eprom.
Please note that this is a part of a designing project and we are not al

did u simulated it on ISIS
i think that can give u a very deep inside
you can really see if data is being written on the Eeprom
a better way paste your code

I have a program greater than 20K. I decided to use 89s52 and a 27512 to store
this program. I have no ideas using 89 series with rom. There are total two hex codes. One is the program stored in 27512 and the "main" program stored in 89s52. Can anyone post this two small programs ( turn on a led via port a ) so that i can stimulate this program o

What is the mcu you use?
is the mcu set up correctly in proteus?
What kind of display did you use?
Can you post an attachment of the circuit and the hex file.

This Circuit is from the book "8051 Microcontrollers and Embedded System Using: Assembly and C" by Mazidi, Page 375. The Circuit Connection are ok but I am getting logic contentions message in proteus and it is not working? I am attaching mikroC PRO 8051 files + proteus file. Does the access time of eprom causing logic contentions? The LED (...)
