Running C++ programs on the TXT
I've been able to succesfully (cross)compile and run a C++ program directly on the TXT. In the documentation for the TXT-C-Programming-Expert kit that fischertechnik put online 2 weeks ago, it is suggested that you can access the 'transfer area' information via a local TXT TCP socket, and that seems...

Re: TXT-Tricks #1: Per WLAN ins Heimnetz
TXT says: # iwlist wlan0 keys wlan0 2 key sizes : 40, 104bits 4 keys available : [1]: off [2]: off [3]: off [4]: off Current Transmit Key: [1] 40 and 104 bit keys are WEP keys. They are also known as (and equivalent to) respectively 64 and 128 bit keys. No support for WPA, it seems. Willem Evert.

Re: TXT-Tricks #1: Per WLAN ins Heimnetz
I tried to follow the instructions to connect my TXT to my home network. Results so far, with sw version 4.1.6, - I had to use wlan0. Wlan1 said it doesn't support the scan function. - It seems the security key that needs to be entered is a hex key, whereas most home networks work with a pass phrase...

Re: RoboPRO 4.1.6 is available
The open source archive looks like the linux system only. The TXT-specific library sources are not there it seems. Only the .so object libraries.
Disappointing.
Anyway, curious to see who succeeds in building and running this thing.

Auf der TXT klicken Sie auf "Einstellungen" und dann "Netzwerk" und die Netzwerksicherheitsschlüssel wird im Display angezeigt.

Re: TXT Kamera Bildschirm
With my non-ft camera the picture shown by the TXT display is steady and crisp. You can experiment with different frame per second (-f option) and jpeg quality (-q option) settings by editing the Test_fb.sh file to see if you can get a better image on the TXT display.

Re: TXT Kamera Bildschirm
Yes, the TXT can do that. However, there is no easy way to do it via ROBOPro, but the TXT controller is in principle able to display the camera on the screen. There is a way to demonstrate it, but I'm not sure how practical it is. Here's how you do it: - ssh into the TXT controller (connect it via w...

I don't have an ft camera, and I'm trying to use some other webcam (Logitech QuickCam® Pro for Notebooks) with the TXT. However, ROBOPro is not receiving any pictures from my webcam.

My TXT arrived today. I haven't been able to open the package yet. But I don't see an updated ROBO Pro version on the ft website yet. I presume I will need one before I can use the TXT? Any idea when ft will release the updated ROBO Pro (not to mention compilers and open source packages)? Willem Eve...

Re: Encoder
@Ad2 Have you ever tried that? Are the attiny's (with internal clock) fast enough to handle I2C at 400kHz and maintain the counters at a reasonable speed (let's say 1kHz)?

Re: Encoder
I've searched for ICs that take quad encoder signals and deliver a position over I2C, but they don't seem to exist. If anybody finds one let me know. The cheapest solution is likely to build something with an Arduino that takes quad encoder signals and acts as I2C slave to the TX. But for the purist...

Results not very satisfactory. At some point I de...

Re: Programm vom PC aus steuern?
Unfortunately what you're trying to do is not possible with the TX controller, at least not without a bag of tricks (see below). There is no out of the box capability to have a PC (running some program) communicate to the TX controller (running it's own program in stand-alone mode), using bluetooth ...

Re: Segway / I2C-Sensoren
Online mode is not fast enough. In online mode you get status updates every 10ms at best, further delayed by the BT communication, which I think can easily add 20-50ms. I believe I read somewhere that you can get only 2 bytes of I2C data per 10ms in online mode. For the wheel robot I need 6, for the...
