![]() Works with GetThermal - our custom open source thermal video display software for macOS and Linux with radiometric support.Open source reference firmware: GroupGets PureThermal Github.STM32F412 ARM microprocessor - execute on-board image processing without need for an external system.9 Hz colour video over usb using the USB UVC class.Compatible with all production FLIR Leptons, including radiometric 2.5 and 3.5 cores.The radiometric Lepton captures accurate, calibrated, and noncontact temperature data in every pixel of each image. Using focal plane arrays of either 160x120 or 80圆0 active pixels, Lepton easily integrates into native mobile-devices and other electronics as an IR sensor or thermal imager. The FLIR Lepton® is a radiometric-capable LWIR camera solution that is smaller than a dime, fits inside a smartphone, and is one tenth the cost of traditional IR cameras. This is a development kit ready to be embedded into a production system. The PTMini Pro also features four mounting holes, less complex circuitry, and perhaps best of all, USB DFU. It has multiple connection options such as solder straight to the board or a custom cable using the JST-SR port. For developers, its reference firmware and viewer software are open source. Just like its PureThermal 2 predecessor, it ships pre-configured to operate as a plug-and-play UVC 1.0 USB thermal webcam that will work with standard webcam and video apps on all major platforms using a JST-SR to USB Cable, or your own custom cable. Toggle CS of the sensor for 185 ms (see datasheet)Įrror = VoSPI_ReadPacket(&Line, &segment) īut I got 255 all the time.The new PureThermal Mini Pro JST-SR with Thermal by FLIR is a hackable thermal camera for the FLIR Lepton thermal imaging camera core.
