Re: PFC8574 IO Expander mit Robo Pro Coding
I took a look into this data sheet STM32MP157C MPU with Arm Dual Cortex-A7 650 MHz, Arm Cortex-M4 real-time coprocessor, 3D GPU, This one is offering an Optional hardware clock stretching Maybe somebody knows the exact type of the chip set in the TXT4.0. However the questions stays: does the OS supp...

Re: PFC8574 IO Expander mit Robo Pro Coding
I use a PN532 in combination with an FT232H (USB to I2C+GPIO) or with a RaspberryPi 4 (hardware bug older versions), both have no clock stretching, and I have experienced that clock stretching is used during read/write operations of a chip (I2C bus 400kHz) . On the ReaspberryPi5 the clock stretching...

Re: PFC8574 IO Expander mit Robo Pro Coding
The problem with the NFC Reader PN532 is that it needs clock stretching. That can not be test with a simple test, you need a slave that holds down the clock. Does the TXT4.0 has implemented the I2C clock stretching protocol and what are the specifications? The TXT had problems with it. he TXT4.0 I2C...

Re: Fabrik mit Mosquitto Server verbinden.
When you run the MQTT broker locally (on you laptop, raspberry pi or TXT or TXT4.0 and also the node-red dashboard inside your local network, you don't need the bridge. The bridge needs to be used in case that you need cloud functionality. It is possible to connect more factories with one MQTT broke...

Re: Using lego devices with the TXT
The lack of a rotary (quadrature) decoder functionality on the TXT4.0 (and the TXT and TX-C) is a loss. The Incremental decoder sometimes causes problems in various applications if there is loopback. However, if the mechanical transmission is blocking, for example with a worm transmission, an increm...

With my TXT4.0, it works well.
In the settings menu | remote access (scroll settings!): the SSH needs to be activated (default=off).

That definitely sounds like a possible solution but it still seems a bit complicated. There must be a way to communicate with the NFC Reader via libraries that can be installed on the TXT itself, without using the SD memory workaround...

Re: Messung der Stromaufnahme 9V Encodermotor
Be aware that the TXT I2C (SDA, SCL) is 3.3V and it is not 5V tolerant. There is no 3.3V power available at the extension connector. So you need to use a 9V to 3.3V regulator/converter/step down when you are using the TXT power supply for the INA219. The I2C interface of the TXT has been based on th...

Level Shift 5v has not been connected with a 5v power supply? The same for the Gnd.
I miss the termination resistors on both the 3.3V and 5V side.
Suggestion: Check the I2C signal shapes on the 5V side with an oscilloscope.
