Recommended LCD for FLIR Lepton

Post by uhclem »

I have a FLIR Lepton longwave IR sensor working with a Pi for which I'd like to add a small color LCD to make for a portable thermal camera. The Lepton uses both I2C (for camera config) and /dev/spidev.0. Is there an Adafruit TFT LCD which only needs one SPI CS? Ideally it would use the /dev/spidev.1.

I am correct that the pitft display needs both CS pins?

If I absolutely had to, I could put up with using the composite video output and a composite LCD. I have a toy "spygear" IR camera which uses a color Kopin microdisplay as part of a rubber eyepiece which would work. I'm not sure, however, if it's possible to have a VESA-type framebuffer on a Pi, so as to avoid running a window manager.

Thanks!

The capacitive touch PiTFT only needs one CS. However, it uses CE0 for that.
The pinout is shown in the schematic

That's very good. It turns out the code for getting data from the Lepton is easily changed to use either SPI CS.

Thanks for the info.

How did this workout for you? I'm looking to make the exact same thing? Any tips, schematics, code for a rookie? Thanks!
