Proteus Eprom

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. (...)

Hi Bomba, 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. Bye

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

Hello everybody. 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 am getting the error when trying ti simulate 2732 IC in proteus Please help.

What do you mean by not working? Did you try in hardware or proteus? Can you post the Code?

hi guys im in need of the shematics of an hc1 expanded mode wth eprom and ram .(other then hc11 evaluation board or the shematic found in the manual of the hc11) i made one but i m having problems wth it :cry: so any help and if someone have a hc11 model library for the proteus sp7 please pm me thx for all the help W

you can make a custom display model for proteus vsm use this together with a pic problem solved

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.

You can download the rar file: PICBASIC Proton Code, PIC16F84A proteus Simulation DSN Files, and VB developed by Oliver (VB exe is not mine). Can any body develop VB code with 7x5 10 LEDS matrix using pic16f877

hi scaedwian, thank you but is this software better than proteus? i think proteus is the best. regards

proteus Lite can also simulate 16f84a well.

hi all i am trying to interface AT89c52 with the standard PC serial port, but it didn't work:cry: could someone send the scematic for this application?? i have the program in ke*il C. i am using MAX232 and hyperterminal to send and receive characters. anyone have good sw example plz send, thanx alot for your time sala

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

Hello Evrybody, Does anybody know how to write binary file to be loaded to a microntroller for Eeprom initialization using proteus VSM? Thanks

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

Hi leoren_tm, 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

Here is project Led moving message display complete project proteus circuit and c source code.

Hi, Thank for your advice, Ianp. Ok, let me try transfer hex files from PC to SRAM first. I will try the MMC later. May i know temporary can we use proteus to simulate it? Please can you teach me how to use commands? I'm running in Protues Virtual Terminal. PAULMON2 Loc:8000 > what should i type here? When i type "L" the Virtual Termi

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. Alex

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. Can you upload your proteus design and a current version of your source code? I'd like

Hello, can we use proteus ISIS to simulate and verify the function of AT24cxxx Eeprom with 8051 MUC.

Ok Guys, so i have it working in proteus.. (with Device address/write as A0) but on my hardware if i send a write (as seen in pic, value 0x41 to address d'55') .. and then send a receive (from the same memory location).. i get nothing back.. Big thanks to Easyrider83 for his help so far!

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 (...)
