hi, With a 16F877A PIC configure the PIC as the master and just read the I2C 24c04 eeprom data into the PIC. Do you have a datasheet for the IR thermometer which shows the I2C protocols required.? Which language do you use for programming.? If its assembler I may be able to help. E

hello, i'm beginner in this, so plz heeelllllllpppp me .... for "programming to 24c04 with 89c52 in read mode specially; i wants write many values of integer n read continuously ....i m totally confused how to use eeprom in my programming .....i hav attached my prog sample.....plz help me ....this is my last hope....:sad::sad::sad::sad::sad::sad::
Hi all. I've got lcd smartie 2x16 board from sure electronics. Board is in version 1. There is many components missing comparing to v2 and v3 boards. can somebody having v2 or v3 post picture of the board? I want to add temperature sensor (LM75), eeprom (24c04) and some resistors to upgrade my board. I was looking everywhere and there is no i
I am using 24C64 with Atmega32, the concept is borrowed from that of Data-logger from dharmanitech.com. To increase memory I wish to use 24C256 and for some trials I tried to use 24c04. The routines for eeprom are taken from the files from the above link i.e. 24C64.h and 24C64.c. Now the question is th
I know, due to the difference in address width we can't use code for 24C02 while using 24C1024. But I have used 24c04 instead of 24C02 & it is working alright. So my question is that whether code will change for every eeprom or it is applicable for group. I will explain my doubt further. Code A will work for 24C02/04/08, code B will work for 24C
Dear Sirs, Please help me by guiding me to correct the Code i have written. I am using Hyper Terminal for inputting 8 Bytes of data to 8051, which has to be written in to eeprom 24c04 at ADDR 0A0H From RAM location 30H to 37H. After writing cycle is completed, I want to read from eeprom and again save in RAM starting location from (...)
I'm making a distance measuring vehicle.i use pic 18f452.counted data will store at external eeprom 24c04.next when i plug via rs232 to the pc data will show in hyper terminal..i use pic c compiler.will somebody help me to code this project.I'm new.
Hi, im working with 24c04 eeprom I have done already a working code but I cannot understand exactly about the terms of addresses.. I just did the code with trial and error method and it worked but I want to know exactly the right approach.. 24c04 is 4kB eeprom according to datasheet. 4kB = 4096 = 15bits of (...)
plz send program for interfacing pic16f877 with eeprom24c04
i am using eeprom 24c08, i wanto to store an many strings into eeprom one string is of 4 bytes. but i dont know how to put it in eeprom. can anyone send me the code for 8051 (keil) or PIC (using MIKROC) in C language.....the string is of having 1000 each of 4 bytes. plz send me the code.... thankyou... email id: ashu_aka88@yahoo.com[/emai
Free software with minimum hardware, maybe this will help you read and write to eeprom.
The main difference between these two eeproms is in the way they are interfaced with something else .. The 93C46 has 3-wire serial interface (Din, Dout and Clock) whereas the 24c04 uses 2-pin I2C interface and can be easily connected to any host I2C device (or bus) .. Other differences can be found in their datasheets which are readily availa
hi friends, can some one guide me how to write the serial data comming from pc. to the eeprom like 24c04..? i m using 89c51 MCU from ATMEL and using KAIL UV-2 to program it in "c" i can take the serial data out on the ports.. but i am stuck at how to write it to the eeprom like 24c04 and read it back.. on serial port..( (...)
hi i am trying to use TWI on atmega8, i want to write single byte 0xaa on eeprom 24c04 .i am simulating it in proteus.i dont get ack response when i send device address to eeprom ,so i send repeated start condition,i have pulled up the sda and scl lines,also address i use is 0xa0, with all address pins of eeprom gnd in (...)
I use the DSPIC 30F4011 for my project. When I config to protect code. The eeprom alway readed is 0x00. My PCb have designed without the external eeprom such as 24c04 ... Please help me ! Thanks a lot !
Hi, Please find the attached library file for interfacing 8051 family to 24Cxx eeprom chips. this library is 100% compatible with the compiler u r using. Please contact me if u need any help.
Hi all, I know there are some pretty big difference between these eeprom memory. But I forget what it is. The difference could be in the acknowledge bit or the write protection pin. I just can't find the difference. All I remember was that I have to change my design last time when one of the particular mfg. have too long a lead time. Anyone
Hi All, I want to interface the AT89C52 to the serial eeprom AT24c04. i did not make that be4. could anybody send the scematic and the program to read & write to the eeprom??? could u help?? hope so thanks alot bye :D Ahmed
I am trying to make a i2c connection between 24c04 eeprom and pic16f877. I wrote the codes that need for. But I guess, it has some problem. But i can't find it. #define LC01CTRLIN H'A0' ; I2C value for CONTROL BYTE when ; INputing data to the eeprom #define LC01CTRLOUT H'A1' ; I2C value for CONTROL BYTE when ; requesting OUTput from t
