4500AS development kit software?
« on: February 06, 2018, 06:07:50 am »
I bought a "L3 thermaleye 4500" camera which appears to be a prototype of some sort since it has a virtex4 on it and a lot of bodgewires
it uses the same pinout as this core http://spi-wholesale.com/shop/l3-thermal-eye-4500as-core-320x240-50-deg-397/

it works fine but theres no way to make it shutter to clean up the image, does anyone have a line on the software for configuring this core over usb?

Found the usb spec in the forums, wrote a usb driver and have image grabbing working over usb, seems to definitely not be standard as some of the return formats are completely different and some commands are completely missing

if anyone has a 3500as, 3600as, or 4500as and would like to run some tests i can post the code, its libusb1 and python2.7

i cant get the overlay working at all on the camera except for the greyscale at the bottom you can turn on from set_power_user_control but it does seem to offer some radiometric features at least in the spec

attached is a usb grabbed image, takes almost a second and forces shutter every time it runs but good for debugging, next job is building a card to read the data off the digital expansion port so i can get more than 1fps digital out of it

I want to make a cable to connect 4500AS to a computer. I have already cable for high power+video out which came with a core. All voltage return (-) pins are connected already. If I want to add USB connection can I use pins 7 (USB_VBAS), 9(USB_D-) & 10(USB_D+) without connecting ground pin on a USB connector?

The D+, D- and 0V are required. VBUS is normally optional. In some systems the VBUS is used to tell the system that the USB cable is connected..

USB is differential signalling but the 0V screen is recommended.

Thanks Fraser! It looks like I’ll need to connect pins 7-10 for USB connection with optional VBUS connection.

In case you missed it in the manual. Many of these cores require the composite video output to be terminated with 75 Ohms before they will output video. This is done because some cores are used in cameras that contain an internal viewfinder and this is switched off when an external video connection is detected via the termination resistance of the external screen. Most monitors are terminated with 75 Ohms but people looking for a video signal using an oscilloscope can get caught out by this termination requirement.

Some Analog Devices video IC's do this whether you want it to or not.
Annoying at times

I want to share my progress on my little project. I was able to access 4500AS with drivers for 3500AS and Windows XP laptop. Big thanks and credit to Fraser for sharing with me CD with 3500AS drivers!
I installed drivers and GUI on Windows XP laptop. Camera was detected as 3500AS model and at the end of an installation gave me error with code 10 (this device cannot start). I've run Software GUI anyway to try if it see the camera. 2 of 4 modules of the Software GUI detected the camera! Cool! :-) I was able to flip image upside down (for my installation needs) and removed temperature bar. I also wanted to play with a zoom and brightness/contrast but unfortunately this options are not available in a GUI for 3500AS cores. These extensive features are available only in the Software GUI for 4500AS cores. So I'm still looking for a Software GUI for 4500AS cores.
