I have made some progress with the integration of the Lepton Module wth the Arduino Due. I found out that I was wiring Sda and Scl to the wrong pins of the Due board, I should have had them wired to Pinds 20 and 21, and I was wiring them to the “SCL1” and “SDA1” pins.<\/p>\n

I can now get the Serial numbers and setup information out of the lepton, such as:<\/p>\n

beginTransmission
\nreg:2==0x6 binary:110
\nSYS Camera Customer Serial Number
\nreg:2==0x7 binary:111
\nbusy
\nreg:2==0x6 binary:110
\nreg:6==0x20 binary:100000
\npayload_length=32
\nFFFFFF7E
\nFFFFB57F
\n5D5E
\n5CFD
\nFFFFF4D7
\nFFFFD7EB
\nFFFF96F5
\n7D47
\nFFFFDCD7
\n7570
\n55F9
\n7CFF
\n5CFF
\nFFFFDEEB
\n3D94
\nFFFFD55C
\nSYS Flir Serial Number
\nreg:2==0x7 binary:111
\nbusy
\nreg:2==0x6 binary:110
\nreg:6==0x8 binary:1000
\npayload_length=8
\nFFFFF017<\/p><\/blockquote>\n

However I am still getting garbled data over the SPI bus. I can’t seem to get it to work at all, no matter what I try. Is there anything obvious that I could be missing here?<\/p>\n

In an attempt to make my code as simple as possible, I created this sketch:<\/p>\n

#include “SPI.h”;<\/p>\n

int data[164];<\/p>\n

void setup()
\n{
\nSerial.begin(9600);<\/p>\n

pinMode(10, OUTPUT);<\/p>\n

SPI.setDataMode(SPI_MODE3);
\nSPI.setClockDivider(0);
\nSPI.begin();<\/p>\n

Serial.println(“setup complete”);
\ndelay(1000);<\/p>\n

for (int i = 0; i < 164; i++) {
\ndigitalWrite(10, LOW);
\nint response1 = SPI.transfer(0xFF);
\ndata[i] = response1;
\ndigitalWrite(10, HIGH);<\/p>\n

}<\/p>\n

for (int i = 0; i < 164; i++) {
\nint response1 = data[i];
\nSerial.print(i);
\nSerial.print(” “);
\nSerial.println(response1);
\n}
\n}<\/p>\n

void loop()
\n{
\n}<\/p><\/blockquote>\n

But I am just getting a string of mostly 0’s, with some other numbers in there.<\/p>\n

I am making progress, I aim to have a simple thermal scanner prototype working this week.<\/p>\n

The images below are of the FLIR Lepton Camera, and the camera wired up (correctly, as far as I know) to the Due.<\/p>\n
