With the lowest cost per pixel in the Lepton family, low power consumption, and simple integration, Lepton FS provides integrators an appropriate thermal capability for innovative thermal monitoring products in smart building automation, security, occupancy sensing, and more. 
These units balance performance and price, enabling monitoring applications where radiometry is not required and pixel-level image information is less important than broad thermal data.
If response timing between Vsync and SPI CS is >3ms, there will need to be improvement in the latency of the interrupt/SPI read process.Available in a limited supply, Lepton FS is a non-radiometric 160 x 120 resolution micro thermal camera module with reduced thermal sensitivity, reduced scene dynamic range, and up to 3% inoperable pixels but the lowest price ever for a factory Lepton. Negate issues with signals not latching properly with SW or electrical Pull-up/Pull-down. #Flir lepton usb driver#
Try to capture moments where the driver "fails" or triggers discards and resyncs. Look at the SPI CS, MOSI, and V sync signals with a logic analyzer. Typically, when this helps, the delay is either +2 or +3 (1.0ms and 1.5ms respectively) Tuning the Vsync delay parameter in the Lepton SDK can help with lepton-host communication. It is worth a try if issues are present where lepton is not working consistently. Adding a delay between the Interrupt driven by V sync and SPI read may be necessary in some circumstances. 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".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. #Flir lepton usb drivers#
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.
