Computers like the Raspberry Pi are about the size of a credit card and have computing power on the order of full-sized PCs from a few decades ago. Not only are the components themselves smaller, but their supporting infrastructure is as well. I found a partial fix adding spidev.bufsiz=131072 sentence to /boot/cmdline.txt (thnx to Luke Van Horn) now the image is not splitted in 4 bands (maybe they are just 2 but more in synch) but the frame rate is still poor (0.5 - 0.25Hz).Integrated circuits, chipsets, memory modules, and all kinds of other transistor-based technology continues to get smaller, cheaper, and more energy efficient as time moves on. Of course I tried with a different RPi0W unit without any appreciable difference. I don't think it's a problem of hardware resources since top CPU load during my test on RPi0W was never over 30%. I had no issues using the same configuration on Raspberry Pi 3 B+, video frames are played at the maximum rate (~9Hz) without any visible artifacts.
Of course I tried the code reported along youtube video but the result is always the same (except for the color palette). Someone tried succesfully the same configuration? I know someone did since there's a video of my same configuration running fine: I tried also changing CE0 with CE1 (and changing spi device code accordingly) without any positive effect as it was obvious. I tried also with more Lepton3 specific code without more luck (same issues). The application is not reporting any error/exception during execution. I think is some kind of problem of SPI bandwidth or loss of synchronization. more probably 0.25 Hz) picture looks like is dived in 4 bands and mixed in the wrong order or taken with a different timing (attached a sample). I'm trying to use raspberrypi_video application from this (official) repository:Įverything complied correctly after installing all required libs and after a little rework to adapt the code to the Lepton3 module (different picture size among other) I can see frames coming out but the rate is poor (well below 9Hz.
I2C and SPI busses have been enabled trough raspi-config. I followed all official FLIR recomendations: connected Lepton module to Raspberry in the correct way ( SPI0 port, CE0 as CS pin). I'm trying to use FLIR Lepton 3 module with Raspberry Pi 0 W board running Raspbian 9 Stretch.
