Example of lepton spi thermal sensor

download and build lepton spi driver

1. git clone from Linux stable

    git clone git@vtxgit.vivotek.tw:bsp/linux/kernel/stable.git
   

2. checkout commit ebc00e27093163d23408bcf0b9177391228c1a9e

    git checkout ebc00e27093163d23408bcf0b9177391228c1a9e

5. make kernel

    make vienna_defconfig
    make
   

6. build driver

    cd drivers/thermal/flir_lepton/
    make
   

load driver and run app

1. copy lepton.ko to your device

2. insert lepton driver

    insmod lepton.ko spi_bus_num=1 spi_speed=13000000
   

3. run rtsp/vospi

    ./rtsps -c stream_server_config.ini &
    ./vospi -c Resource/VIC/0/os05a10_2560x1920_ch0.cfg -a Resource/AutoScene/autoscene_conf.cfg &
   

use spi device

1. run vospi by spi device(ex: /dev/spidev3.0)

    ./vospi -c Resource/VIC/0/os05a10_2560x1920_ch0.cfg -a Resource/AutoScene/autoscene_conf.cfg -s /dev/spidev3.0 &
   

Lepton device version

1. Lepton 2.5

    ./vospi -t 2 -c Resource/VIC/0/os05a10_2560x1920_ch0.cfg -a Resource/AutoScene/autoscene_conf.cfg -s /dev/spidev3.0 &
   

2. Lepton 3.5

    ./vospi -t 3 -c Resource/VIC/0/os05a10_2560x1920_ch0.cfg -a Resource/AutoScene/autoscene_conf.cfg -s /dev/spidev3.0 &
