MSP430F169 I2C slave receiver mode

Hello, I have a problem with the peripheric I2C of this uC (MSP430F169) in slave receiver mode. The own adress interrupt is provocated only 20% of time. Have you an exemple code ("C" or assembler) in this working mode ? Thank you.

Hallo, I use the µC MSP430F169. I have problems with the hardware I2C, too. A few axamples I have only found on the TI-site. I use it in the master mode. Writint to a EEprom is ok, but I can't read from it. I can see the coffect answer-byte from the EEprom on the bus on the oscilloscope but the µC dont't catch it!?! Do you have example code in "C" for this mode? Oder irgendjemand auch auf Deutsch; allerdings dennoch in "C" :-) Gruß Rainer

Hi, i dont't have anymore Problems witch the i2c-EEPROM. The "Receive-Interrupt-Routine" works. Now I have only problems with the permanent writing to the I2C-LCD. On every programm-loop there is a comman to write to the LCD. That takes five or ten minutes good; but then the µP hangs. And i don't know why ! Rainer
