 		 #109719 - Really ?
Responding to: ???'s previous message
Erik Malund said:
ONLY re clocking, a transfer of the code from LPC to 668 took 3 minutes.


The 668 I2C was identical to the old 552 and thus you can relative easy reuse code for it.

But the LPC764 I2C was identical to the old 751, which use a complete different HW-I2C.

I needed to write complete different I2C drivers for the 552 and for the 751. It cost me several days but not 3 minutes.


And the Philips 528 contain a complete different HW-I2C as the 552 or the 751.


The Atmel AVR use a simlar I2C as the Philips 552.

But I can not say, which I2C use other manufacturers and other mc families, because its uninteresting for me as long my SW-I2C can do the job also.

P.S.:
If you stick only on microcontrollers with HW-I2C similar to the 552, then naturally there is no big problem to reuse the code also.
