Is the TE-M1 a software downgraded TE-Q1 ?

[TooQik]

Wireshark has a USB capture interface, just make sure you check the option when installing Wireshark.

Once installed, open the USBPcap interface you plug the camera into; I have USBPcap1 and USBPcap2 interfaces on my PC - #1 is the front USB ports and #2 is the rear ports. When the interface is open, plug in the camera and then perform a Read Flash command. When this is done with the M1 I see data exchange in both directions in what appears to be an initialisation process.

Hopefully you capture something of interest.

Here you go: https://files.fm/u/dcsvjpcw

old version is in the play store

Is anyone able to share this version of the Android software please? The link no longer works and I'd like to try it out on my M1 and see what difference it makes.

Thanks in advance.

You can find the patch on the website: https://www.thermalexpert.eu/deutsch/supportmaterial/

I've just tried the "centered" software version and I'm not seeing any difference in positioning when switching between the different versions - exact same picture each time. 

Here's the pictures from the three different versions I used - the one thing I did note, is there is a slight change in image size with the centered version.

[Vipitis]

So there are few ways to explain this. If the Android app on PlayStore had no update they must have fixed it in firmware for all the M1s they had laying around and only those that were sold before the issue was known have he window not centered.

The difference in size is just scaling and screen format. The TE app offers to stretch or 3:4 at real resolution or something. The captured .CVS should be normal in both versions.

Do we know how the Q1 and M1 compare with the official desktop software? And if there was any update for M1 Support/fix?

[TooQik]

The problem for me is that my window isn't centered on the M1 I have.

I can see this in two ways:

• There is a very slight curvature on the top of images I capture.
• I can confirm the column and row start positions my camera is outputting when it is initialised by the software; in my case this is column 100 and row 0.

For anyone interested in what the internals of the TE-M1 looks like, I decided to get intimate with mine and took her cover off.

So we have:

TPS65021: Power Management IC For Li-Ion or Li-Polymer Powered Systems

and

MT25QL128ABA:  128Mb, 3V, SPI Flash memory device. https://www.micron.com/products/nor-flash/serial-nor-flash/part-catalog/mt25ql128aba1ew7-0sit

So the imprint seen top right. "TE Engine V..." Any idea what is beneath the sticker? Is it like a version number?

[TooQik]

I didn't peel the sticker off to look under it unfortunately.

Joe-c's picture of his Q1 in this thread also shows the same sticker in the same position. What is different is the flash chip used on my M1, plus I have a pin header connector soldered to the board where Joe-c's Q1 has the exposed pads. Wonder what this header is used for?

[TooQik]

And for completeness, here's a picture of the back of the PCB on my M1, which I neglected to post yesterday.

Unfortunately I didn't have any cleaner handy to allow me to clean the thermal pad residue off the components to get a better picture of the part numbers, but I can see that the large chip on the bottom left is a Cypress CY7C1041GE.

Sorry for OT:

Seems like the M-1 in 30Hz version is currently on sale from the known Austrian distributer for 399€:
https://www.ebay.de/itm/Warmebildkamera-Infrarotbild-TE-M1-240x180-Pixel-30Hz-Warmebild-Thermal-Expert/283121690439?hash=item41eb5e2747

Yes and it´s still valid until end of april.
If ordered, it comes as the 30hz version, I think I´ll buy this.
There is also a option for 350°C but I couldn´t find out how much this will cost.
I asked if this option can be buyed later, no it must be ordered with the cam.

[Martin72]

Why is the TE-M1 not listed under the products of the TE/i3 Website ?
Only the several variants of Q1 and V1.

[bugi]

They don't list the Q1's 19mm lens there, either..  and probably few other things are outdated, too. But I guess this forum is not the best source of answer to the question. Maybe they could answer it themselves:
http://www.i3-thermalexpert.com/contact/

I only used that site to dig out some documents/info that I could not find through the EU site.

[frenky]

Could somebody please upload some CSV files from M1 module?
I would like to test my app (ThexConvertGUI) with M1 support...

[TooQik]

Here you go frenky.

There are four thermal images with their corresponding temperature CSV files. I've included files with temperatures that range from below zero and up to about 380 degrees Celsius. These were all captured with version 20.1.6 of the Android app.

One thing to note, the wood fire image CSV file recorded the last four rows of temperature data as NaN. I've not had this occur before so I'm not sure why this has happened.



Update regarding NaN CSV entries: I deleted the dead pixel map and retried a capture and all new CSV files now have the full 180 rows of temperature data again.

[frenky]

Thank you!

Can somebody make foto from image processor (under label)?

Help me please recognize this chip
