If I use shiftin or a similar routine it works fine. Here is my shiftin clone. Why won't HARDWARE SPI work ?

Might it be because I connected the SPI's SDO (output) to the ADC CS line ? (see first post, first attachment)

Code:
DEFINE OSC 20
DEFINE LCD_DREG PORTD' Set starting Data bit (0 or 4) if 4-bit bus
DEFINE LCD_DBIT 4' Set LCD Register Select port
DEFINE LCD_RSREG PORTD' Set LCD Register Select bit
DEFINE LCD_RSBIT 0' Set LCD Enable port
DEFINE LCD_EREG PORTD' Set LCD Enable bit
DEFINE LCD_EBIT 2' Set LCD bus size (4 or 8 bits)
DEFINE LCD_BITS 4' Set number of lines on LCD
DEFINE LCD_LINES 2' Set command delay time in us
DEFINE LCD_COMMANDUS 3000' Set data delay time in us
DEFINE LCD_DATAUS 100
