#105254 - I2C Responding to: ???'s previous message |
All the RTC chips usually use the I2C protcol, so you should learn about the I2C communication hardware and software and then you can chose any chip. but if you just need the time and you have two I/O's free on your micro you can use DS1307. it also has some amount of internal battery backed up RAM too.
if you need more help mail to my email account. vinod |
