I2C problems - iamthewilldinkel - May 8 17:09:55 2006
Hi all,
I'm using the HCS12 on a PK-HCS12E128 dev board. I'm trying to
interface with a D51307N real-time clock chip using the I2C bus and
having some issues.
Can anyone please point me in the direction of some resources which
may help me crack this nut?
PS: I looked in the forum for support; the only I2C code -- which was
commented in French -- I could find was for the GPIO pins. This chip
has an I2C controller built in.

I've got some code for the 9S12DP256 and DS1307. The code is in=20
assembler not C, so it may not be suitable for your purposes, but if
you contact me off list I shall be happy to send it to you.=20
