A grabber for BeagleBone Blue to acquire thermal images from Lepton3 sensor

Demo: Video 1 - Video 2 - Video 2

SPI buffer size must be set to 131072 20480 bytes (safe value) to allow the receiving of a full segment for RGB data

(61 packets x 240 bytes = 14640 bytes)

$ sudo nano /boot/uEnv.txt

Search for the following line:

cmdline=coherent_pool=1M net.ifnames=0 quiet cape_universal=enable

add spidev.bufsiz=20480 at the end of the line, e.g.:

cmdline=coherent_pool=1M net.ifnames=0 quiet cape_universal=enable spidev.bufsiz=20480

Save, exit and reboot

$ mkdir build
$ cd build
$ cmake ..
$ make

To be sure to acquire every available frame set the CPU of the BeagleBone Blue to max speed using the command rc_cpu_freq by Robotics Cape SDK:

$ rc_cpu_freq -s 1000
