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.

To solve the problems with connecting two I2C-master devices: See the data sheets of these products: https://coptonix.com/en/products/i2c-rs232-adapter-slave/ ( https://coptonix.com/en/products/rs232-i2c-adapter-master/ https://coptonix.com/en/products/rs485-i2c-adapter-master/ ) https://www.mikroe....

The laptop is not a MQTT-client. An application can be a MQTT-client. On a laptop you can have on or more MQTT clients running. The MQTT client's can be running on the same laptop as the MQTT-broker. In the installation map of Mosquitto: \Program Files\mosquitto\ you will find two nice client applic...

@beepere, How good is your knowledge and experience with MQTT? The original 9V factory with TXT's is using shared sensor outputs and not MQTT. You can only subscribe to MQTT topics. You can develop drivers (MQTT-clients) for IO-ports and other hardware which are decoding and converting MQTT messages...

The original 9V factory with TXT's is using shared sensor outputs (IO-ports) to signal to the warehouse that the color selector unit has a product with a certain color available at one of the 3 output lanes of the color selector.

Nice book.
