Re: I2C and bootloader control on the same pin

2005-04-21 by wittrockjeff

Well... thats kind of what I was talking about when I mentioned 
putting the buffer in between my external device and the first I2C 
channel.  I guess I was wondering if I am missing anything in terms 
of using the second I2C channel without having to use some kind of 
glue logic or buffers (yeah.. I guess I'm lazy).

Also, just wondering about the logic in sharing the boot loader pin 
with the I2C SDA.  I know there is a limited number of pins, but 
this seems to be a pretty bad pin to try and share.

Thanks,
Jeff W
