@freda997 hey I'm actually rigging up a lepton 3 as well with a breakout board v2.0 on a rPi 4 I'm still a bit new to all of this, but was wondering which resource you used for setting up your wiring. I was following a guide on FLIR and referencing the datasheet but there aren't any great ones yet for the 2.0 board. Not sure if you'd be willing to provide how you did it? I will let you know if I run into the split frame issue as well, more than happy to colab.

Hi @hrdunn, sorry for not getting back to you in time. Here is the guide I used when I set up the wiring, and here is the datasheet for 2.0 breakout board. Let me know if you have any more questions. I am definitely open to collab!
@freda997 I actually managed to get it working using a combo of those things as well. Never wired a board before so I was pretty lost the other day. I am also not experiencing the splitting issue you ran into. I am using the lepton3-dev
branch though so I think that could be the solution for you if you are still getting the split. I am running into an issue extracting the raw radiometric data. My understanding is there should be some way to get the temperature of each pixel but I have no idea how to do that and it doesn't seem to be documented here. No idea if you have tried that yet. I've got a friend who is an electrical engineer and C++ guy taking a look at this document so if I figure that out I will let you know.
@hrdunn did you figure it out?
This is what the output looks like if you're not using the lepton3
or lepton3-dev
branch of this code, but are using a Lepton 3 part.

Hi @freda997 I am also new to this, and I am working with raspberry pi zero, lepton 3.5 and breakout board v2.0. I tried to follow the instructions for the old breakout board (https://learn.sparkfun.com/tutorials/flir-lepton-hookup-guide), but it failed. Did you have the same problem?

@hrdunn Hi, how is it going? I am new to this and really want to listen to your experience☺️
This is what the output looks like if you're not using the
lepton3
orlepton3-dev
branch of this code, but are using a Lepton 3 part. Hi Kurt @kekiefer, sorry for contacting you directly here. I saw you replied to this lepton issue and guess you might have a lot of experience with this. I am really struggling with using Pi zero W, lepton 3.5, and breakout board V2.0. I tried to follow this guide https://learn.sparkfun.com/tutorials/flir-lepton-hookup-guide , but after I installed the example software (https://github.com/groupgets/LeptonModule/tree/master/software/raspberrypi_video) and run the raspberry pi_video, I didn’t get anything. Here is what showed on the terminal. I would be super appreciated if you could give me some help. Thanks very much!
Best, Leyuan

Hi,
I am trying to configure my breakout board v2 with this tutorial : https://lepton.flir.com/getting-started/raspberry-pi-lepton/ . But I am stuck at the step where it is asked to "Copy the RaspberryPi onto the Pi". I don't really understand what that means. Can anyone help me with that ? I have a RPi 4B, and a lepton 3.5.
Thanks :)
Hi,
I've been trying to get the program running using Lepton 3 with the new release of the breakout board, but images I am getting are either corrupted or split like the picture below. I tried to adjust the SPEED in Lepton.py and haven't gotten the issues fixed completely, but it does make a difference. So I suspect it is a sync issue with SPI. According to the datasheet, the new version of breakout added a vsync output signal, yet the pylepton library doesn't reflect the changes. So I wonder could this be the cause of the problem. BTW I am using Raspberry Pi 4.![op](https://user-images.githubusercontent.com/32531210/79536159-2e337380-8034-11ea-9f60-b8db3ba243e7.png)
