Re: TXT Wie eine Shared Library neu laden?

there is a mechanism to set and to get more variables but step for step. Thank you for the clarification. Yes, SLI can handle multiple variables, but RoboPro can only read one or write one at a time. So sending a MQTT message requires two boxes: one to set the channel, another the set the value. Sa...

Re: TXT Wie eine Shared Library neu laden?

It seems the SLI libraries are limited to send or receive one value at a time. This is a serious limitation for building an interface to MQTT, with at least two values: one for the variable ( e.g. 1 for temperature) and another for the value ( e.g. 19,8 °C). Let's hope a next release of RoboPro will...

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...

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...

Re: Gyro Sensor aus Robotics Competition Set

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.

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?

Re: Variable abspeichern und nach TXT-Neustart wieder aufruf

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...
