CCS vs datasheet
PostPosted: Sat Jan 05, 2008 9:07 am     Reply with quote
Hi im have problems with connecting spi on my 18F4550 because the datasheet shows that SCK=RB1, SDI=RB0 and SDO=RC7, but when i choose the hardware spi function in picwizard(in CCS compiler) it shows SPI_CLK=C3, SPI_DI=C4 and SPI_D0=C5 i dont know what to believe, or if im completely wrong??

The datasheet is always leading. The pins suggested by the CCS compiler are the pin numbers as used on most other PIC processors but are wrong for the PIC18F4550.
Maybe be this has been fixed in a newer compiler version. What is the version number of your compiler?

I don't have the latest compiler versions but maybe someone else can check the correct pin numbers in the PIC wizard?
