I discussed a similar solution on the Parallel Processing page and used it on Very Large Model: Defining the Processes.

I didn't flash 4.5.1 but tried 4.6.5 from the SD-card.

Although reported initially last 13 January 2016, I opened a thread at Board index > fischerwerke > Kontakt mit fischertechnik > I²C speed stuck at 400 MHz on Robotics TXT.

As per TXT and I2C bus speed , it looks like the issue I reported 13 January 2016 is still open. Running the exact same program on RoboPro but targeting RoboTX and then Robotics TXT Even when the speed is set to 100 kHz, the Robotics TXT I²C bus runs at 400 kHz on the Robotics TXT. image001.jpg On t...

Thank you Carel for the explanations and the references.

IMHO, you deserve to publish a whole technical article about I²C in the next issue of ft-pedia!

Contrary to the eLearning Portal page in German at https://www.fischertechnik.de/de-de/service/elearning/spielen, the page in English at https://www.fischertechnik.de/en/service/elearning/playing doesn't list the ROBOTICS TXT Smart Home and its link https://www.fischertechnik.de/en/service/elearning...

For the BBC micro:bit, you may want to have a look at the interface micro:bit IO F5 board by Didacta Advance specifically designed for fischertechnik models. Similarly, Michael Klein is sharing pxt-fischertechnik , an excellent Makecode extension for the fischertechnik microbit IO F5 board. barrier-...

At the Hannover Toy Fair 2019, fischertechnik presented the Starter Set for micro:bit on its Teaching range aimed at academia. This set leverages the hugely popular BBC micro:bit micro-controller with an interface board. barrier-3_orig.jpg The set is due to be launch later on 2019, but ​I managed to...

I'll do. Thanks!

@Freeemind I've read your post Fischertechnik Fabrik mit Node-Red Programmieren about fischertechnik and Node-RED. Have you developed the Node-RED yourself, or is it a standard feature provided by fischertechnik? I've designed an extension for the Robo-TX and Robotics TXT controllers, the smartNode ...

Since ftDuino supports the Arduino standard, I've implemented support for this board on embedXcode , embedded computing on Xcode. embedXcode is a plug-in for Xcode, the free IDE from Apple. https://embedxcode.weebly.com/uploads/1/1/6/2/11624344/8556189_orig.png As a today, build and link against the...

The BNO055 and BNO080 are very nice sensors, and very convenient to use as all the calculations are carried out by the embedded Cortex-M0+ MCU. Here is the box sensor, called smartIMU ... smartimu-1-2_orig.jpg ...and the driver was very easy to develop and implement for RoboPro. capture-2017-09-20-2...

I really enjoyed the Fan Club Day, saving many hours of driving. I attended the training on robotics live, and asked and watched the training on the 3D printer after the convention. I really appreciated everything was available in English and guess many fischertechnik fans abroad did the same. The o...

Problem with the BMX055 is, the sensor only provides raw values, not the computed Euler angles (yaw, pitch, roll), quaternion, rotation vector and linear acceleration.

I'd recommend the BNO055 instead, also operating on I²C bus and from Bosch Sensortec.

Thank you!

Interesting project!

One question: The NEMA 14 stepper motor from Pololu has a shaft diameter of ⌀ 5 mm “D”.

How to connect it to the standard ⌀ 4 mm used by fischertechnik axes?

EEPROM implies erasing a block (a set of continuous memory bytes) before writing a new value. I'd recommend FRAM, which combines RAM ease-of-use and Flash data-persistence. FRAM chips are available for the I²C bus, come with different operating voltages (3.3V or 5V). Look for Cypress FM24C04B , whic...

I've developed smartNode, an I²C-driven BLE interface that connects the RoboTX to Node-RED. Node-RED provides a nice IDE to design and run a dashboard. http://reivilofischertechnik.weebly.com/uploads/1/1/6/2/11622422/2016-12-10-18-13-56-capture-orig_orig.jpg http://reivilofischertechnik.weebly.com/u...
