Thanks for such a quick reply !
We have tried slowing down the motor speed but it still does not work.
As soon as the RED(9V) cable is connected, the digital input shows "1" and stays that way.

Hello all, We were wondering if it is at all possible to use the Encoder motor with the ROBO Interface ? Specifically with the encoder cable as a digital input. Can one simply connect the cables to the interface like so; RED(data) to I1, GREEN(ground) to I1 and RED (power) to 9V+ ? Or is the encoder...

hello Drugovi, we are trying a similar connection but haven't been able to succeed with a servo function.

have a look at this thread and maybe you could expand further for your requirements.

Hello all This was a good exercise to generate code to handle numbers more than 32767. Below is our attempt where we split the score into tens of thousands 10^4 Score1 = nominal value Score2 = above 10,000 (less than 10,000,000) Main Program http://i47.tinypic.com/2f07l8k.jpg Subprogram 1 http://i47...

hello all.

has anybody been able to use this app successfully for more than a few times ?

the connection seems to be quite unstable and we get 'failed connection' more times than successful ones.

does anybody have any tips on how to get a successful connection ?

Thanks

13-Nov ?!

that's less than a week ago !!

okay then, will have to download that now - thanks !

Hello all, Firstly, we are wondering if anybody has a link to an english version of the documentation found in C_Compiler_RoboTXC\ftMscCDemo_V1.2\Doc , namely the C_Compiler_RoboTXC.pdf file (The download package from the link on the fischertechnik.de page (English version) is also in German) Also, ...

Sorry I forgot... maybe something like this: int cmd_1_received; //your global flag int timer_1; //this variable increments each ms void cmd_received() //your event handler { if (command == command_1) { cmd_1_received = 1; timer_1 = 0; } } void loop() { if (cmd_1_received) { if (timer_1 > 5000) { ....

Hello Rei Vilo,

have you been able to look at the problem ?

regarding Ad2's comment;

"it is better to set a global flag on interrupt and poll that flag in the main loop."

that would mean triggering the ReceiveEvent (based on a flag) in the loop(), which is not possible, is it ?

Hello Ad, Thank you for your reply but we didn't understand too much as our experience is even less! Our aim is to connect the TX-Controller to a servo microcontroller to handle more than 4 servo motors. (In our case, we are using a Spider (Arduino-compatible) Servo microcontroller.) We then pre-loa...

Hello all, we're back. After studying the Arduino forums we have succeeded in making a connection between the TX-C and an Arduino-compatible Spider micro-controller. With a simple LED code; #include "Wire.h" int led = 13; // on-board LED void setup() { // initialize the digital pin as an output. pin...

thanks for the correct syntax. one question about the (variable?/keyword?) ' howMany ', in the above case it would be just '1', right ? if (for example) it were '2', then the event would be waiting for a second byte to be sent from the TX-C; your informative website has shown us how to do this :) bu...

thank you very much for your clear reply. i'm now wondering if it's actually less complicated than i'm making it out to be ! for the case of " RoboPro just to send data to the I2C device "; on the Arduino side, we have to prepare the functions beforehand for each case of byte that will be sent. woul...

Hello all, We are trying to learn how to connect non-FT components; sensors, servos, etc to the TX-Controller, now that the I2C connection has finally arrived. Our background in electronics is not very good but we know a bit of basic programming from dealing with HTML & PHP. We have assembled the va...
