Note: The PureThermal 2 does NOT include a FLIR Lepton imaging module and. Get a step-by-step guide to building a successful Lepton design. No clue- Sounds like you just changing values without understanding what they supposed to be doing. view Lepton data on x86 Linux and macOS platforms or even on a Raspberry Pi. Here is the 40 pin schematic of the Raspberry Pi, you can easily find I2C interface SCL and SDA. Grow your business with Lepton - the leading professional-grade micro-thermal camera module. This software you talk about and the arbitrary values. For example, moving to Raspberry Pi would cut the compute unit cost from 100USD to 35USD. (They recommend 25Mhz) Did you provide that? The magic of the MLX90640 Thermal Camera is that for the same price the resolution jumps to 24×32, giving each frame 768 different temperature readings. I suspect they did not include a crystal in the LEPTON to keep the size down and embedded devices usually have access to some kind of constant clock any way. Now we know Raspbian is not very great at generating consistent clock rates consistently so you may be experiencing problems with this - The same way may other FLIR'ers are experiencing. I assume you got it hooked up to SPI correctly but one of the problems seems to be the Input Clock rate. So looking around really I noticed the protocol used on the Lepton is VoSPI (Video over SPI) Frankly never heard of that before but its plausible because the frame size is 80 x 60, which is not a crazy amount of data with some kind of AGC applied format which is selectable (Did you select the correct one?) jamesh wrote: Removing the IR filter doesnt give you a thermal imaging camera - just a camera that can see in to the near Infrared.
