Thank you, it help me a lot with 24LC04 EEPROM code.

[@SMtrainingacademy]

Thanks for your support

[@jrlvarghese]

It was a great help for me, Thank you so much for the video.👍

[@SMtrainingacademy]

Thanks for your feedback

[@coolchriss]

I did not understand, 0xA0 is the device address , 1010000 or 0x50 uesd in writing address, you used in both writing function and reading function, I thought reading function will take the address 1010001 or 0x51!! Could you please explain it😢

[@Sekhar_Home]

Sir, u r giving video back to back. Pls send video day by day. So we will not missed any.

[@SMtrainingacademy]

Sorry I thought of giving a complete video series fully is it ok so that you can learn everything in a sequence

[@siwaneducation7444]

I use at24c64 eeprom

[@yashrajshinde1085]

Don't we have to set the desired BITRATE when using Wire.h lib. ?

[@yassinebouanani8702]

realy a great video from you but just i would now the difference between the differents eeproms ic ( exemple AT24CXX, 24CXX etc....)

[@siwaneducation7444]

Hello sir this program only print 255 in my serial print , please help me I want to read and write eeprom in atmel 24c64 , Please send me suitable code for this eeprom ic

[@SMtrainingacademy]

Ok that is becoz the line is in high state only that’s y it is read as max value of 8bit variable

[@SMtrainingacademy]

Please check the datasheet whether the sequence is ok for that eeprom

Can an i2c slave microcontroller write to 24c08 eeprom? for example the attiny441 lists only an i2c slave interface. Can it write to eeprom?

[@SMtrainingacademy]

Actually if a microcontroller supports i2c peripheral it will be able to write or read from i2c bus, since i2c is an multi master communication.

[@kirkkeinanen592]

@@SMtrainingacademy I guess I’m confused. the atmega328p states that it has master and slave interfaces. The attiny441 states that it just has the slave interface. What’s the difference between the two?

[@SMtrainingacademy]

@@kirkkeinanen592 give me sometime I’ll refer attiny441 datasheet and I’ll will clarify your doubts

[@SMtrainingacademy]

I read the datasheet and understood that as per your thoughts you are right, attiny441 cannot be configured as i2C master it is dedicated slave so you cannot use this controller for initiating and fetching data from another slave device like memory or rtc..., instead this can be used a slave for another master device or microcontroller for communication purpose.

[@kirkkeinanen592]

@@SMtrainingacademy thanks for the insight. I’ve read that i2c devices can be used on an spi bus. I’m going to try this method to write to the EEPROM.

[@masoudjafarzadeh]

Hi sir Thank you for sharing with your code we can just read and write 256 byte (just one block ) how can i read and write mor than 256 byte My eeprom is 24lc04

[@SMtrainingacademy]

You may have to use more memory sized eeprom like 24lc08 or 16 or 32

[@masoudjafarzadeh]

@@SMtrainingacademy Hello, thank you for the offer I wrote a program to read and write the second block of EEPROM memory 24lc04 now i can read &write 512 Byte.

[@vijukv3546]

Thanks for your video. can i know how to read and write string from external memory?

[@SMtrainingacademy]

You can only write data byte by byte and store as ascii characters you can write your own function for that too

[@cristiangs2307]

Hi! question... how to write float number? Regards

[@SMtrainingacademy]

Ya you can convert the number store it in decimal format right?

[@cristiangs2307]

@@SMtrainingacademy i don t know how convert and save...thanks for you repply

[@SMtrainingacademy]

@@cristiangs2307 if you just multiply any float number with 100 you will get two decimals values into a decimal number so you can store that Ex: 24.754 x 100 = 2475.4 You can store 2475 right 24 is decimal and 75 is fractional part
