Ad7715

I have to read some very low voltage values (0-10 mv) with pretty decent accuracy, so an AD7715 was chosen as the A/D to be interfaced with an 18f2320. The only sample code I can find is C code to read the AD in an 68HC11. Has anyone interfaced to a similar A/D with picbasic that can share a code sample of setting up and configuring the A/D with SPI?

Thanks,
nik
