No clue- Sounds like you just changing values without understanding what they supposed to be doing. Re: FLIR Lepton not working with RPI Sun 7:40 pm Try using CS0 instead of CS1, ( pin 24 instead of 26 ) this caught me out, although the software may have been updated since then. This software you talk about and the arbitrary values. Connect the FLIR breakout to the Raspberry Pi GPIO according to the diagram below. (They recommend 25Mhz) Did you provide that? I suspect they did not include a crystal in the LEPTON to keep the size down and embedded devices usually have access to some kind of constant clock any way. Now we know Raspbian is not very great at generating consistent clock rates consistently so you may be experiencing problems with this - The same way may other FLIR'ers are experiencing. I assume you got it hooked up to SPI correctly but one of the problems seems to be the Input Clock rate. When inserting it into the breakout board be sure to use proper personal grounding, such as a grounding wrist strap, to prevent damage the module.So looking around really I noticed the protocol used on the Lepton is VoSPI (Video over SPI) Frankly never heard of that before but its plausible because the frame size is 80 x 60, which is not a crazy amount of data with some kind of AGC applied format which is selectable (Did you select the correct one?) The Lepton module is extremely sensitive to electrostatic discharge (ESD). Note: The PureThermal 2 does NOT include a FLIR Lepton imaging module and will need to be purchased separately or in the Dev Kit. The PureThermal 2 and GetThermal both support the radiometric mode of Lepton 2.5 & 3.5 and can view Lepton data on x86 Linux and macOS platforms or even on a Raspberry Pi. It’s easy to get started with the PureThermal 2 with the open source software application, GetThermal. If USB isn’t neccisarily your desired medium, this board has also been fitted with 0.1' pins to interface over UART or I 2C. With a Lepton inserted into the PureThermal 2 you will be able to achieve 9Hz color video over USB using the USB UVC class. For developers, its reference firmware, viewer software, and hardware schematic are all open source!Įach PureThermal 2 is equipped with the reliable STM32F412 ARM microprocessor capable of processing images without any external system inputs. Each PureThermal 2 ships pre-configured to operate as a plug-and-play UVC 1.0 USB thermal webcam that will work with a standard webcam and video apps on all major platforms. The PureThermal 2 Smart I/O Board is a hackable thermal USB webcam breakout for the FLIR Lepton® thermal imaging camera core.
