hii...all,
Now im doing a project in pic18f452 using mikroc compiler . Im facing a serious problem that any 1 of the 2 protocols can b implemented at a time. bcoz serial clock [scl,RC3] is sharing by both spi and i2c. But I need the both. So can anybody tell me how can I do that in mikroc..

you can make use of both but at a time, only one.

all you have to do is, initialize SPI or I2C before start using it in your program.

I don't know the details of mikroc but in general an I2C connection is fairly easy
do using general I/O pins.
IE.. put a data bit on one pin then toggle a second to act as a clock.
I have done this in assembly language for a 18f2455.

Learning all the time
