Okay this is what I have so far:
#include <SPI.h>
#include <stdint.h>
//*******Arduino MICRO SPI pins********
#define SS 17
#define SCK 15
#define MOSI 16
#define MISO 14
#define SS1 2
byte dataBuffer[8];
void setup() {
Serial.begin(9600);
SPI.begin;
pinMode(SS, OUTPUT);
pinMode(SCK, OUTPUT);
pinMode(MOSI, OUTPUT);
pinMode(MISO, INPUT);
pinMode(SS1, OUTPUT);
}
void loop() {
delay(20); //MLX90333 startup takes 16ms
SPI.beginTransaction(SPISettings(160000, MSBFIRST, SPI_MODE1)); //320000 is about max
delay(5);
int j;
for (j=0; j<10; j++){
digitalWrite(SS, LOW);
delay(20); //Short delay necessary here
int i;
for (i=0; i<8; i++){
dataBuffer[i] = SPI.transfer(255); // Must transfer 1's, 0's don't work
}
digitalWrite(SS, HIGH);
SPI.endTransaction();
Serial.print(dataBuffer[2],8); //Print 3rd byte, MSB for Alpha
Serial.print(" ,");
Serial.print(dataBuffer[4],8); //Print 5th byte, MSB for Beta
Serial.println(" ,");
}
for (j=0; j<10; j++){
digitalWrite(SS1, LOW);
delay(20); //Short delay necessary here
int i;
for (i=0; i<8; i++){
dataBuffer[i] = SPI.transfer(255); // Must transfer 1's, 0's don't work
}
digitalWrite(SS1, HIGH);
SPI.endTransaction();
Serial.print(dataBuffer[2],8); //Print 3rd byte, MSB for Alpha
Serial.print(" ,");
Serial.print(dataBuffer[4],8); //Print 5th byte, MSB for Beta
Serial.println(" ,");
}
}
I wasn't sure how to use the array, although I can see where it may be useful. Until I understand how to use it, I'll leave it out.
The code does compile and uploads, but when view the serial monitor it only shows two columns where I would like to get four (two for each sensor displaying the two angles of the magnetic field each of them senses.) Furthermore, I the readings I see are all zeroes accept when I make a really rapid movement over one of the sensor- then I see a very short few lines of non-zeros before it goes back to all zeros.
I looked walked through the code a couple times and everything seems like it should work... any suggestions?
