hi everyone i am trying to communicate between two lpc2148 through I2c. I am having problems in the slave side, i think so. The slave does not acknowledge properly(Hardware). i used logic analyzer in order to check this. In protues simulation everything looks perfect and the I2c debugger shows that the data is properly received and acknowledged by the slave. In hardware I used pullup resistors (1K,1K). and i used power supply(3.3v). I use interrupt service routine for both master and slave. if u have any ideas about this please support me.
Thanks in advance
