The C-code described below has been compiled for the MAXQ2000 microcontroller, which is used on the MAX7456 evaluation (EV) kit. The complete set of software routines is available in this application note. The routines are self-documenting, so little additional description is provided. The C-Code below is also available in the following files: spi.c and MAX7456.h
The code uses the standard nomenclature for the SPI lines. The MAXQ2000 processor is the SPI master and the MAX7456 is the SPI slave.
CS is the same as is used in the MAX7456 data sheet.
SDIN is referred to as MOSI (master out slave in).
SDOUT is referred to as MOSI (master in slave out).
SCLK is referred to as CK.
