You must write your own I2C routines. It is a shame that CCS have no TIMEOUT for I2C as they do for RS232.
If you take I2C out of the box checkout Philips I2C bus extenders. Using the bus extende ... |

CCS provide an example driver, LMX2326, which is very similar.
You just need a small PIC e.g. 12F635
I assume you are at home with RF synths and it is just the MCU you are asking about.

Pin 7 must be VDD
Also, delete the line setup_spi(FALSE); |
