Hi Rubem, Does anyone know how to run a Python program and display the results on WinSCP's console? Not sure if it helps with observing output in WinSCP, but you can observe the output from your python program right in the VSCode if you start this program on the TXT40 via the SSH. I've provided a de...

Hallo @Holger, The RX controller in "Advance Mode" is a USB composite device with 3 virtual devices: 1. Mass Storge device CIRCUITPY 2. Virtual COM port A - can be used for the REPL 3. Virtual COM port B - can be used to send and receive binary data to and from the host The COM ports will often be a...

Hi @MatzeW, Seems that access to the CIRCUITPY drive, which is an USB "Mass Storage" (MSC) device, is a byproduct of the corrupted boot.py file you encountered :). Initially this CIRCUITPY drive is available only when RX is in the "Advance Mode", which is not set with default factory settings in FW ...

Hi @calliope,

You can get the actual FW version from RX controller using this script:

Hallo zusammen, ich habe ein Problem mit dem NFC Leser einer Lernfabrik. Dieser erkennt immer nach einer Weile wenn die Anlage eingeschaltet ist die Warensteine nicht mehr und packt alles in den Ausschuss-Behälter. Es gibt dann auch nicht mehr diesen Piepton, den der NFC Leser bei erfolgreicher Erk...

Hi Dirk,

You are welcome. Happy to hear someone found it usefull!

Hallo XGBC,
Vielen Dank für Ihr Interesse an Kameraverbindung. Ich habe den Sensor ov5640 bestellt. Wird nach Erhalt der Bestellung fortgesetzt.

Hi MasterOfGizmo, Thanks for the tip! The ov5640 sensor looks promising. Also there is ov5640 driver in the Linux source tree with complete set of register values for BT656 embedded synchronization configuration: // SPDX-License-Identifier: GPL-2.0-or-later /* * Copyright (C) 2011-2013 Freescale Sem...

Here we go: robo-tx-rev-c-pcb-camera-a.jpg It results in two news: Bad one - there is no ISI_HSYNC and ISI_VSYNC signals available on the connector. These signals used by ISI controller to gate data capture from the data bus: 61-HSYNC-and-VSYNC-Synchronization.png Good one - there is another mode fo...

Thanking a lot to noname donator and an underground dental service we have a whole bunch of x-ray images of PCB. It's time to trace wires between CPU and CAMERA connector:

Thanks for the tip! I have tested some software samples from at91sam9260-ek board on the ROBO-TX and they works fine. Just need to tune LD script according ROBO-TX memory map. At this point I can control onboard red LED, buttons, I2C(TWI) bus, USB device interface and DBGU serial port. ROBO-TX under...

Hi Björn,

I just ask myself why are you doing this? Just to see if it´s possible?

Yes. Just to have a fun. You can imagine the ROBO-TX as underdeveloped baby waiting for someone to stitch back the camera module. Also I guess it's a good way to learn embedded systems development.

Hi Carel, The main problem is that the OS on the TX-C has no source code and no documentation available Here we have number of options: 1) Disassemble, decompile and reverse engineer 4NetOS from the binary dump of onboard NOR FLASH. Than integrate custom executable task into existing 4NetOS. Also th...

According to the datasheet for AT91SAM9260 CPU it has the Image Sensor Interface (ISI) that supports direct connection to the 8-bit parallel bus sensors and up to 12-bit grayscale sensors. It has FIFO buffer for pixel data and DMA interface - so we can offload frame data transfer job from the CPU. I...

Huge portion of work I see here. Good luck!

Da die ft Kamera eine USB Webcam ist, kann man nicht am TX Controller anschließen und nutzen. Okay. I understand that I can't get image from USB camera in the TX - there is no USB Host interface routed from the CPU :). At the same time TX has the CAMERA connector. May be it is a kind of standard ty...

Dear community, I'm a happy owner of the 10 yo ROBO TX controller. TXC is the best education controller I know, but I can't find any information regarding access to integrated CAMERA interface. Is there anybody who has success in connecting a camera to the CAMERA interface connector (not EXT)? Yes, ...

Hello Arnoud,

Is there already more in depth documentation of the 'Fish.X1'-protocol available?

Unfortunately I don't know any more sources of documentation for the Fish.X1protocol. Only "PC_Programming_RoboTXC_en_V1-5.pdf" from fischertechnik.de

Successfully tested fx1parser V0.3 with ROBO Pro 4.6.6. Download here - https://github.com/mr-kubikus/fx1-arduino-parser

Thank you. Inputs voltage reading confirmed.
