# 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 &
