Hi all, I am new to this MCU's MSP430. Presently i am trying to write a code for interface of MSP430FET149 to EEPROM (BR24C02F-W) via I2c but i am unable understand how to write a code.. please can one guide me how i could start and is there any procedure of writing code for interface... help me out ... thanks harsha S

What don't you understand. If you do not know how to write a program
you
need to study a beginners book on programming, or, better still attend a
course. If you simply don't understand the MSP 430 instruction set then
download some example programs from the Ti web site and study them with
SLAUE10B chapters 5 and 9 in front of you until you understand what is
happening. there is no easy way.

Hi harsha. Dont get diheartened. first do these things. 1.read the msp430f149 user guide and device specific datasheet available from www.msp40.com. 2. read i2c specs from philips. Then u will be able to interface ur msp430 to the eeprom easily. If u need any help mail to me. bye, N.Vijayasarathy shastri Design Engineer Shastri Technologies __________________________________

Hi, thanks, But for MSP430f149 Microcontroller there is no I2c Specific controll register and no much stuffs i can get. I would like know what are the steps to be fallowed to configure the or establish the interface with the EEPROM. If you have any test codes in C which will tell regarding the i2c communication that will be great for me. thanks harsha s --- shastri vijayasarathi <shastrinvs@shas...> wrote: > > Hi harsha.

There are several examples on ti.com/msp430 describing how
to use I2C and how to connect to a I2C EEprom with any controller.
Please surf before you ask. ;-)

hi harsha , try this out. There is anapplication not in www.msp430.com called "Interfacing EEPROM to msp430x11x". it has the number"SLAA115". just give this number in serch tab and u will be easily able to find it.I have attached the file for u. follow the instructions in the pdf and u can easily interface ur msp430 to ur eeprom. bye, N.V.S.Shastri __________________________________________________
