Hi all,

I'm trying to implement a SPI to I2C protocol converter in
a 16F877 PIC. The PIC will be a SPI slave and a I2C master,
receiving "commands" over SPI and talking to I2C slave
devices over I2C.


ARM CPU                 PIC 16F877                   ???
SPI master <-----> SPI slave | I2C master <-----> I2C slaves


I want to implement SPI in the PIC in hardware (MSSP module)
and will have a software-based I2C implementation. The main
problem seems to be accomodating the different speeds at
which SPI and I2C may operate in the PIC side.

I'm wondering if someone has done something like this in the
past?

G.
