Re: Logitech Gamepad

Hi Karl, It is very simple. Logitech does not support LINUX. If someone of the LINUX gurus is able to deliver this third party driver (version 0.8.8) and the library compiled for the TXT-LINUX then you are able to plugin your Logitech USB gamepad (receiver) directly into the TXT. You only need to de...

Re: remote standard gamepad SLI for TXT

Hi Hamlet, Interesting response, thanks. 1. For me is the TXT and the fischertechnik firmware a given. It is a good quality toy. Also very suitable to use as support for education with the focused on mechatronics. The moderate speed and real-time behavior are not that important here. The TXT with th...

Re: Logitech Gampad

postscript: Logitech self doesn't give LINUX driver support for their Gamepad (710, 320, Rumblepad 2 devices!!!! It is not a fischertechnik problem!!!! The XBOX gamepads have in general more support. It is possible to use USB gamepads directly on the TXT (or the wireless receiver). The operating sys...

remote standard gamepad SLI for TXT

I created a SLI (RoboPro extension elements) which add gamepad functionality to the TXT. This based on the recent W3C gamepad API, The client is a web application, that's run in a modern browser (which implements the gamepad API). The application supports a virtual joystick (2) and a standard gamepa...

Re: Websocket zur Sensordatenuebermittlung - TXT Controller

For the Mosquitto MQTT support you only need to update the firmware on the TXT's to 4.6.6 or 4.7.0(including web socket support) . The binary for the factory software and instructions can be found here The sources can also be cross compiled under Windows with Eclipse. But for this you will to modify...

Re: Encoder-Motoren drehen nicht auf tiefer Stufe

This is a very old issue. The problem is much more structural and is not limited to children's toys alone. The outputs are not special for engines. PWM limits energy and not engine speed and is linear. {PWM% * Voltage * Current.} The engine also has hysteresis (starting torque) and there is also the...

Re: Encoder-Motoren drehen nicht auf tiefer Stufe

It looks like that In this case Dirk Fox answer is right. The trail sensor follower is a closed control loop (control enginering). The stability of the control loop depends on the sample frequency and the delay in the loop it self. In the online mode, the USB connection is the most stable one. WLAN ...

Re: TXT's in a stand alone wireless ip-network

A new point of research in this project could be: Can a TXT in the access point mode also act as IP-router? This functionality is necessary when 2 or more clients are connected and client A will be communicate with client B. To test if this kind of commands will work. https://linuxcommando.blogspot....

Re: TXT's in a stand alone wireless ip-network

@Richard, thanks, I hope that the practice is doing this. My expectation is yes. The USB address can set in the same two files, but I didn't test it yet. On Windows there exists a routing table, probably on UNIX too. I hope to have everything, including the Civetweb SLI, ready at the North-convention.

TXT's in a stand alone wireless ip-network

Idea for a project to create a combination of a couple of TXT in a private stand alone netwerk. One TXT (m) could act as a WLAN access point. One or more TXT's could act as clients in this same network. A other device could also be part of this network. Points of research: 1) how the DHCP server of ...
