When I understand correctly the biggest advantage of the EV3 is the open software and possibly the bigger display. There are however some disadvantages for use with ft: not compatible with RoboPro (so you would have to use the Lego programming system) and incompatible hardware (connectors, encoder m...

Since we have access to the I2C interface now, other interfaces are becoming less interesting, nevertheless I have taken a look at the TX ultrasound sensor. It appears that the digital Ultrasound interface is an interrogating system. When no sensor is connected and the input is in ultrasonic mode, t...

Das geht ähnlich wie bei der Control Set. Einfach ein Motorausgang des TX mit ein Eingang des Soundmoduls verbinden. TX und Soundmodul sollen die gleiche Masse (- Pol) haben.

Well umfish for Delphi is a good start, what exactly is your problem?
I guess you know how to program in Delphi, right?

In the video it shows the robo interface. Not the TX so the RF link should work.

Ein 5000mA Trafo wurde sicherlich das Problem lösen, es sei das Problem liegt in der Verdrahtung. Das Gefahr ist allerdings das ein Kurzschluss gleich die Verdrahtung vernichtet. Deshalb ist es besser unterschiedliche Stromkreise zu verwenden die z.B. auf 1000mA gesichert sind. Also 5 Netzgeräte von...

Meinst du so etwas?

Das ist ja wirklich interessant! Um welche Servo handelt es sich genau? Passt die Hebel auch? Ist er baugleich mit der altere oder der neuere Control Set Servo, ich glaude die neuere hat ein Metalgetriebe, nicht?

Es ist ein Zugmagnet, glaube nicht das es ein originellles Teil ist.

Es wurde helfen das gesammte Program hier zu zeigen.

Indeed, the TX is I2C master and need to request the data from the Arduino. Therefore the Arduino need to be configured as an I2C slave.

Hi, I hope you read English. Programming a TX in online mode (i.e. the program is running on the PC) is not difficult and not that much different from other PC programming. For the TX you need the ftMsclib which resembles the ftlib but has some important differences. Both have the concept of a trans...

Hi Rei,
Nice solution. Which IC did you use?

Ich glaube auch das du das nie schaffen wirst. Sicherlich nicht mit ft alleine. Auch Gyro, Kompass und GPS sind wahrscheinlich zu ungenau. Das einzige wäre ein absoluter Koordinatenreferenzsystem mit z.B. ein Kamera.

@thomasdr Maybe you can write your own wrapper, I did it once for C# and ftlib. Perhaps you can use the same principles for VB.Net and ftMsclib. here are the problems and solutions I encountered: The .Net framework and C# are becoming increasingly popular. Using ftlib requires a different approach b...

A TX C program can read memory locations, e.g. 16 bytes at a time and send them as a BT message. In a more elaborate approach you could implement a kind of RPC scheme. For instance by sending a function code and some parameters and receiving return values.

But now you could implement a readmem yourself, getting 16 bytes at a time

Well basically it can be done! In practice it is a lot of work and ft has not disclosed all necessary details.

A similar problem was discussed here. http://forum.ftcommunity.de/viewtopic.php?f=8&t=1503 . In principle it is possible but it is not easy.

CDC and SPP will provide you with a virtual com port. Over this port you can communicate in ascii (console) mode. File transfer is with xmodem 1k, should be available for linux. The X1 protocol for online mode you will have to program yourself.
