Their schematics and sourcecode is open source and available on their website.

FLIR LEPTON USB SERIES

An example for this is the pure thermal series by groupgets.

A great mitigation, if possible, is to allow lepton to run on an external processor like a single core MCU so that all that it handles is Lepton video and i2c communication and also transmission to the host platform.

A Lepton reboot may be necessary if there was a significant event where lepton SPI was severely affected by host activity.

Resyncs are necessary many times when lepton is put "put of sync".

FLIR LEPTON USB DRIVER

Although the driver may be working, it is still possible that there may be dropped frames due to interruptions.

Lepton is sensitive to being put "out of sync" with the host, and requires consistent SPI transactions.

It may be required to increase the priority of the lepton interrupts, the SPI read, and the allocation of memory.

The lepton driver and the interrupts have proper priority on the host system, and are not being interrupted by other processes.

It is recommended that the lepton be isolated on the i2c bus to understand if there is interference from other slaves on the i2c line.

i2c communication interference can cause problems with lepton.

Changes can be made using SDK commands over i2c Lepton by default will output 14bit monochrome data and not RGB888.

The lepton is set in the correct video output mode that the driver expects.

It contains a Master clock (different from SP clock), that helps isolate variables to address.

It is recommended to test using the lepton development board v2 for driver debugging.

SPI clockrate is 20-24MHz, and meets specification defined in the lepton datasheet.

Resync is being utilized (See Datasheet), for lepton 3/3.5 it is possible to use 60ms assert period rather than 185ms defined in the datasheet.

Ensure the driver is using DMA to read data into the host.

Use an interrupt driven driver, like our examples, that utilizes V_sync (GPIO3) from the lepton and use it to trigger SPI Read.

Make sure the lepton is fully seated in the Molex Socket.

There are examples online for drivers from groupgets as well as from FLIR, but every platform will be slightly different when integrating lepton. Lepton 3.5 has strict requirements for timing when reading data out of the module and onto the host platform. kelvinA has updated the log for Tetent.John Loeffler has updated the project titled Uno Plus+.AVR has added details to Accessibilità.AVR has updated the project titled Accessibilità.AVR has updated the log for Accessibilità.chris owens wrote a comment on Roktrack - Pylon Guided Mower.Ostracus on Making The Case For All-Female Exploration Missions To Mars And Beyond.Foldi-One on Making The Case For All-Female Exploration Missions To Mars And Beyond.spaceminions on Converting On-Grid Electronics To Off-Grid.NQ on Making The Case For All-Female Exploration Missions To Mars And Beyond.spaceminions on The Bicycle (and More) Explained.Twisty Plastic on Making The Case For All-Female Exploration Missions To Mars And Beyond.Dude on Making The Case For All-Female Exploration Missions To Mars And Beyond.smellsofbikes on A Paste Extruder For Normal Printers.Michael Black on Making The Case For All-Female Exploration Missions To Mars And Beyond.Posted in hardware Tagged flir, Flir lepton, ir camera, IR imaging, lepton, thermal camera, thermal imaging, thermal imaging camera Post navigation That’s pretty cool and worthy of mention.

This is also project number 3000 on hackaday.io. You can check out some video made with the Lepton module below. The images are a bit too large to be processed with all but the beefiest Arduinos, but if you’re thinking of making Predator vision with a Raspi, BeagleBone, or a larger ARM board, this is just the ticket. The Lepton module is controlled over I2C, but the process of actually grabbing images happens over SPI. There’s a group buy going on right now, with each module costing just under $260.

With this breakout board, you’ll obviously need a Lepton module.

Just try to find a higher resolution thermal imager that’s cheaper.

Compared to professional models, the resolution isn’t that great, but this module only costs about $250. Here’s a breakout board for Flir’s Lepton.Įlectron artisan recently got his hands on a FLIR ONE, and doing what he does best, ripped the thing apart and built the world’s smallest thermal imaging camera. Somewhat surprisingly, Flir is allowing anyone to purchase this module, and that means a whole bunch of robotics and other various electronics projects. It’s the sensor in the FLIR ONE, a thermal imaging camera add-on for an iPhone. Thermal imaging cameras are all the rage now, and one of the best IR cameras out there is Flir’s Lepton module.
