I2C callback functions

Kaustubh Kanhere

Hi Everyone,

I've been facing difficulty in writing code in call back functions of i2c.

I mean I am totally blank.

Please help me.

I am trying to communicate in between LPC936.

I have programmed one as Master and the other as slave.

Thanks in Advance!

    Thanks Eric for your help! But I am gonna need more of it.

    I have configured one Micro-controller as slave with address 0x01(I2ADR=address<<1. Therefore I2ADR = 0x02).

    Now Master (another Micro-controller) calls slave i2c_receive(0x01). But unfortunately Master enters status, slave address + read transmitted, NACK received.

    Now I2DAT in master is 0x03 i.e 0000 001 for address and LSB = 1 for read.

    Please help me!

    Where possibly did I go wrong?

    Thanks in advance!

    I am sorry previously i hadn't mentioned Micro-controller used.

    I am using P89LPC936.

    And the problem i had discussed was seen on hardware.

    Thanks!
