re: 16C74 and I2C
Brian, this is not much help but I've been working on a 16C74-based
weather station and, amongst other things, it talks to remote displays
via a serial bus. The remotes are 16C84s. I tried implementing I2C using
the 16C74 hardware and software in the remotes. I had a lot of problems
so I went with an SPI-style 3-wire interface implemented in software using
the same SPI-designated 16C74 pins, and it's working fine. I chose not to
use the 74's SPI as I'm talking to both custom and standard SPI devices.
Well this just be my ignorance but my experience with PIC's and I2C has not
been very successful.
