Getting SPI to work with MAX13362

Using Arduino Networking, Protocols, and Devices

Recently I have been working on getting the Maxim 13362 chip to work with the Arduino Mega. I'm not to sure what's going on, but every time I try to read the register of the Maxim chip, the value that gets returned is value that I sent. (which seems interesting considering sending a dummy byte will usually send u back the byte in that register.)

#include <SPI.h>

#define CS1 53

byte maximChip_1_Array [4];

void initializing(byte chipArray[], const int pinNum)
{
  digitalWrite(pinNum, LOW);
  chipArray [0] = SPI.transfer(0x00);
  chipArray [1] = SPI.transfer(0x00);
  chipArray [2] = SPI.transfer(0x00);
  chipArray [3] = SPI.transfer(0x00);
  digitalWrite(pinNum, HIGH);
}

void setup()
{
  SPI.begin();
  SPI.setBitOrder(MSBFIRST);
  SPI.setDataMode(SPI_MODE1);
  Serial.begin(9600);
  SPI.setClockDivider(SPI_CLOCK_DIV4);
  pinMode(CS1, OUTPUT);

void loop()
{
  initializing(maximChip_1_Array, CS1);


///print out byte in each register
  Serial.println("CHIP 1");
  Serial.print(" Array 1 - C1: ");
  Serial.println(maximChip_1_Array [0]);
  Serial.print(" Array 2 - C1: ");
  Serial.println(maximChip_1_Array [1]);
  Serial.print(" Array 3 - C1: ");
  Serial.println(maximChip_1_Array [2]);
  Serial.print(" Array 4 - C1: ");
  Serial.println(maximChip_1_Array [3]);
}

Post a wiring diagram!

You know that you write the command register 0 in every round, don't you?

What value did you expect? Why don't we see the serial output you got?
