On the PC the binary stream of data can be parsed easily by looking for the 0xdeadbeef header on each frame. This example takes the SPI data stream from the Lepton module, buffers it and send it out the USB VCP device.
STM32F3Discovery_ChibiOSĭownload and install ChibiOS_2.6.5 into the same directory first. Note that most Arduino hardware does not have enough memory to buffer the thermal image. This example shows how to read the i2c ports using an Arduino. This is for the Raspberry Pi, see this page for more information See the wiki page for more information: raspberrypi_video a file called image.pgm will be created, you can use GIMP to view the image.to compile the code just run "gcc raspberry_pi_capture.c".add # in front of spi-bcm2708 and ic2-dev.You have to enable the spi and i2c ports first for this code to work. Steps are outlined within this directory. Requires the device's SPI0 tree to be exported to a slot before running.
This example is for the Beagle Bone Black board and runs a basic video feed. Lepton contains a breakthrough lens fabricated in wafer form, along with a microbolometer focal plane array (FPA) and advanced thermal image processing.
The Lepton 2.5 and 3.5 are both also radiometric which means they can output a factory-calibrated temperature value for all pixels in a frame irrespective of the camera temperature with an accuracy of +/-5˚C. The Lepton 2.x camera cores has a resolution of 80 × 60 pixels and the newer Lepton 3.x camera cores have a resolution of 160 x 120 pixels respectively. The FLIR Lepton™ is the most compact longwave infrared (LWIR) sensor available as an OEM product.
