Hi guys,
I have never worked with i2c devices yet and I have to add an RTC (real time clock like DS1307) and a 24clxx memory to my mother board card (PIC16F877) which is controlling a terminal (another card based on a PIC controling an LCD+Keypad) via i2c bus, thus, the i2c bus will have a master (PIC) and 3 slaves ? can there be a data loose since the 3 slaves can send/receive data simultanously ?, for instance, while,I'm displaying something on the LCD (i2C bus is busy), the RTC needs to send real time to the PIC16F877 ...
have anyone made something similar before (and worked well) ?
any help will be highly appreciated.
thanks.
