Gesehen auf "Marktplaats" ein Vintage 8085 Mikrocontroller-Experimentierboard, logisches Niveau 5V. Möglicherweise interessant in Kombination mit einer Fischertechnik Universal Interface: https://www.marktplaats.nl/v/computers-en-software/vintage-computers/m2393693639-vintage-intel-sdk-85-8085-exper...

On the TXT the I2C interface has been implemented as a SLI. De SLI manager knows a issue: it stop working after 4 to 5 secs inactivity. A dummy "keep alive" process will resolve this problem. See old publications about this issue and also: https://forum.ftcommunity.de/viewtopic.php?f=8&t=8342&p=6466...

3 links about updating TXT firmware, also including forced updating from a SDcard. https://forum.ftcommunity.de/viewtopic.php?f=8&t=7699&p=60153&hilit=firmware+TXT#p59605 https://forum.ftcommunity.de/viewtopic.php?f=8&t=7699&p=60153&hilit=firmware+TXT#p59615 https://forum.ftcommunity.de/viewtopic.ph...

However the memory size of the TXT4.0, see also the VScode requirements, is to small for the remote VScode system with Python.

2G RAM is needed, the TXT4.0 has only 512M RAM

For translations, see for example Google translate. =================================================================== There is no manual for this. I have used it before and it works. Move the remote VSC files to a microSD card on the TXT4.0, because the storage memory of the TXT4.0 is too small. T...

What is a TXT 3?
I only know a TXT or a TXT4.0.

Did you try to reinstall the TXT firmware?

RoboPro coding offers only a subset of Python and also of threading. Hereby some links about threading with Python: https://www.simplifiedpython.net/python-threading-example/ https://docs.python.org/3.5/library/threading.html# https://superfastpython.com/threading-in-python/ threads versus processes...

See Google translate for the translation into a different language. @ Jan Thanks for this information. @all Why this change? see: https://www.allaboutcircuits.com/news/how-master-slave-terminology-reexamined-in-electrical-engineering/ This is only a textual change in the "I2C bible" UM10204, this be...

For translations, see Google translate. However the most I2C documentation/information is written in English. About your second question, some elementary information: I2C is a 3-wire communication bus protocol to connect a master I2C device with one or more so called I2C-slaves devices. I2C definiti...

Maybe this can help. Be aware: Some I2C RFID/NFC interface needs clock stretching or an interrupt ( IO-pin). The python RFID lib ask for it. The TXT does not have implemented clock stretching. The TXT4.0, I don't know. For example: Additional background information (PN532): https://learn.adafruit.co...

Yes, it is possible to reinstall the firmware from a SD-card.
And it also possible to do this from scratch.
For that you will need a USB to serial converter.

(For translation you can use something like Google translate.) A stepper is absolutely not the same as an encoder motor. A stepper has no feedback sensor. However their are existing steppers with an integrated quadrature encoder (2 bit pulse, gray coded, direction info). The encoder motor has a puls...

Thanks, I only have experience with both the factory 9v TXT (RoboPro programs) and the factory 4.0 9v TXT (C++ programs). I have given both technical and didactic support/advice in the use of both factories at Saxion HBO business administration in Enschede (NL) and Drenthe College Smart Industry (MB...

The TXT needs always be power on by pressing the button.
The auto-start only takes care to start the application after power on.
with the learning-factory that is pressing the 5 TXT's their buttons in the right sequence.

Your string is not a float, check the string and adjust it.
