Hello,
I want to test I2C and since I have no I2C device I used I2C0 and I2C1 of a same LPC2148 board.
I2C0 is master transmitter, I2C1 is slave receiver. But I can't make it...

Hi Paul,
Just to clarify the misunderstanding here.
1) I check for 0x08 in I2STAT. 0x08 is not SI bit. It is a status to indicate that Start condition has been transmitted.

That's odd!
I'd say the problem with your latest piece of code was using CONSTAT instead as CONSET to check for SI as you did in your first code example.
CONSTAT doesn't have a...
