Hi guyz, I am trying to run i2c on Tiva C TM4C123GXL board. After Initiating the communication, Controller is always busy and does not come back in idle state. I don't know why buti am pretty sure, it is not sending the data to 24c04 because in "Master Bus Monitor" register i am seeing the SCL and SDA always low. I wasted my whole day to solve th
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
24C64 needs 2 word address bytes to access it, while 24c04 needs 1 word address byte Check out the datasheets for more information
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 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.
24c04 is 4kB eeprom according to datasheet. 4kB = 4096 = 15bits of addresses right? so the address would be 0x000 to 0x2FFF ?? The datasheet says organized with 32 pages of 16 bytes each, the 4K require a 9bit data word address for random word addressing This is a [B
PIC 16f877 can be interfaced with eeprom 24c04 using I2C. find out more about pic , eeprom, I2C and atleast try n write a program.. if you face any problem we can giv u suggestion for correcting the program. Good Luck
for 24c01 to 24c16 (including 24c04) you have only 1 byte for addressing... (works fine with 24c01 and 24c02) for extra addressing you must use the 3 lower bits of I2c-address so you must chage your writing/readings routines... {the extra stuff over 0xA0 to the 3bit extra addressing... } unsigned char ReadBYTE(unsigned int Addr) {
Hi All, How can I load data to M24c04 eeprom? I am very new to this. I don't have any basic idea about writing data to eeprom. Can we write the data using a PC? Do we have to use special hardware for this operation?
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 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
ATMEL website has application notes to do that. It might be for a different part number of chips. Just remember that the controller 89C2051 is software compatible with 89C52 and 24c04 is software compatible with all the 24C series memories. Hope that Techie wouldn't mind :
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
