Re: question on 8051

Use SEARCH with “8051 AND keypad” and BANG .. you have plenty posts on this one ..
Then use SEARCH with “8051 AND eeprom” and you will find a lot of entries on that one ..
Example:
#1153457

Try to combine both together ..

Then, if you have any problems, ask specific questions ..

Re: question on 8051

Hai,
You choose AT89C51 and 24C32(EEPROM) for your work.
1) For key board interface ( Hardware as well as code) Refer: Kennath Ayala book or Myke predco book.

2) For EEPROM refer Atmel AT24C32 datasheet.
3) you need to follow I2C protocol for writing and reading the memory.

Bye Bye
