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 want to generate a HEX file for an eprom in PROTUES.
Is there any way or any software to do ?
Thanks in advance

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

There are a couples of inaccuracies in what you said.
First of all, is not fully true that ALE is actives in every conditions. The ALE signal (Address Latch Enable) together with PSEN (Program store enable), RD and WR (alternate functions of pins P3.7 and P3.6) give the access to two type of external memory operations; accesses to external [

This is complete 5x7 19 matrix Moving message display with RS232 Control.
atmel 89c51 is used.column are scan by 74ls164
source code are in c keil c51
proteus simulation file is included.
Yes this may be the best one... I must try this if i have any problem i will ask, as I m very new in C and good in assembly.

i think proteus is the best.

For PCB fabrication you could check following thread a nice discussion going on:
Since You seem to be starting MCUs I would suggest usage of something like PIC Basic Pro if you intend to learn Microchip mcu and Bascom AVR if you intend to learn Atmels mcus.
Both families have their own pros and cons, d

I don't know exactly what do you want (what means the "dual Dot-matrix") but I'm attached here my old projects about this thema. These are using at89c2051 and 6 or 8 pieces of 7*5 LED dot matrix modules. I think the 7*5 is enough but it's easy to modify the circuits and the programs to 8*8 matrix.
For this projects I'm used proteus

Can you post an attachment of the circuit and the hex file.

I'm using 1827. Must warn you, this is a very new cpu. PICKIT2 can't debug it, only programming. And MirkoProg can't too. And the simulation model in proteus have many bugs.

I am compiling my code in MikroC and debug mode is off. its working on the bread board but not in ISIS.
I just find it strange you are only having problems with RB6 and RB7 and they happen to be the pins required for Debug.
