programming multiple DS1337

[lerameur]

Hello,

Has anybody aver tried to program more then one DS1337 from a single Pic? It does not seem that is possible from the datasheet as ll the ds1337 are identical and unlike some EEPROM there does not seem to be identification code.

P13 of datasheet...

The slave address byte contains the 7-bit DS1337 address, which is 1101000, followed by the direction bit (R/W), which, for a write, is 0.

talks about slave mode and master mode, read and write. I dont see multiple ds1337 programming..

All DS1337s have that address. I've never seen an I2C RTC that allowed you to change the address. Normally, there's no need for multiple RTCs.

Why are you trying to use multiple RTC chips?
