Re: Error using OpenCV: histogram function

Ah ok, didn't think of that. Previously, I just used cv2.imwrite(...) and only for using histogram, I added hist_image1 to it.

Re: Error using OpenCV: histogram function

Hi Lars,

hist_image1 = cv2.imwrite(filename_res, result)

Re: password problem after ftc firmware upgrade to 0.9.5

Dear Esther, Dear hvn, perhaps you could describe your problem in more detail: Is your problem about the community firmware (cfw) or about the original ft-firmware? My problem is about the cfw. I assume you downloaded the cfw and installed it on a SD card. Then you boot your TXT from this SD card. D...

Re: password problem after ftc firmware upgrade to 0.9.5

Hoi,

Was ik even vergeten. Dank voor je reactie.....

Overigens: mijn ft-firmware versie is 4.6.6. Geen idee of dat iets met mijn problemen te maken heeft.

password problem after ftc firmware upgrade to 0.9.5

Hi, After having display problems using an earlier version than 0.9.5, I upgraded, which was rather easy. However, now I find that the password isn't accepted anymore so I can't access the TXT controller when running the ftc firmware. Earlier, I could solve it by re-inserting the microSD card, but n...

Re: Linux Kernel question TXT

I guess you're mixing up the kernel version and the community firmware version. I think you are looking for cat /etc/fw-ver.txt Which shows the community firmware version. Best regards, Lars Thank you, that code looks like it. This did work and showed I had to upgrade the cfw, which solved 2 proble...

Re: Linux Kernel question TXT

I do not own a TXT Controller, but anyway. You approach ist totally correct, uname -a shows the kernel version (a complete OS may have extra infos). For the GUI check the HTML source (view source) in your browser. I would expect some script/adblocker supresses the output. What Browser did you use? ...

Linux Kernel question TXT

Hi, I want to check the version of the community kernel on my SD card, since the latest version is 0.9.5. However, when I give "uname -a" I get "Linux FT-txt 4.1.37 #2 PREEMPT Fri Jul 14 01:42:07 CEST 2017 armv7l GNU/Linux". And for some reason, accessing the FT-GUI shows me a blank screen on the TX...

Hi Huub, I just notice that someone is going to organize something in Enschede next year. I am very curious how it will be their with the number of visitors next year. The area Roombeek is not so easy accessible by cars so it will be not so easy to come from outside Enschede and go to there. Hi Car...

Great models and fine pictures, thank you Huub!
My favorites are the platonic body dodecahedron, picture 3009, made by Stef Dijkstra, the Magic Machine, picture 3014 and the ft-man taking a shower in the video!

Many greetings,
