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.December 12, 2017 at 5:29 am in reply to: LCD based digital alarm clock with digital thermometer using 8051 microcontroller (AT89C51) #14678sharonParticipantConnect the 4×4 keypad with port 1 of the microcontroller. Connect 16×2 LCD display with port 2 of the microcontroller (make sure that all the data pins of LCD display are connected to the microcontroller correctly). The rs (register set) pin of LCD is connected to pin 3.5 (pin number: 15) and en (enable) pin is connected to pin 3.6 (pin number 16) of the microcontroller. Connect crystal to pin 18 and 19 of the microcontroller. We are using 12MHz frequency Crystal. For reset, circuitry connects a pushbutton to pin 9 of the microcontroller. We can also use a potentiometer to adjust the contrast of LCD.

sharonParticipantGet the stepper running first; write a program that makes it turn in one or the other direction. If you don't know how to do that, the canonical google search (atmega32 +stepper) looked promising.
