An I2C or SLI connection will be lost in online mode if no new action is taken within 5 seconds, it does not restart. This point has already been addressed in some example programs in 2020. Because the ROBOPro elements of I2C also run via an SLI, the same workaround applies to both.
- For I2C a dummy operation that is repeated within 5 sec. This can be a simple read.
- For an SLI a dummy operation to a ROBOPro SLI extension function "StayAwake". Additional information for the SLI developpers only:

Replacement for the original fischertechnik TXT-C-Programming-Kit-4-1-6
This programming kit for the development of remote applications for the fischertechnik TXT controller contains a library which takes for the communication with the TXT and offers a rich set of higher level API to the end-user. But is also still possible to program directly on TA (transfer area) level.
The solutions and projects are developed and tested with
MS-Visual Studio Community 2019
which is free to download and use.
The original SolutionOnlineSamples is using the C14++ dialect and can also be used with the Eclipse 2020-06 workbench.
The new split-up version (into a solution for the library and a solution for the applications) is using the C17++ dialect.
After downloading a solution, it is directly usable with MS Visual Studio 2019.
The original OnlineSamples structure contains a mixer of the low level library stuff and end-user applications and has been split up into a library solution and a application solution now.
The library has been extended with similar higher level functions as there were available in the ROBO-interface and TC-controller programming kits.
The end-user needs only SolutionTxtApps and can add his projects to it; this solution is also to download directly as .zip file.
Some examples which are using the FtTxtLib or FtTxtLibDll library, including these libs, updates of the original example applications and some test examples.
- The library supports the communication thread and has callbacks (events) .
- It also support a set of higher level API functions as they were also present in the TX-C and Robo-interface programming kits. Like (part of the class
ftIF2013TransferAreaComHandlerEx2):ftxStartTransferArea,ftxStopTransferArea,ftxIsTransferActiv,GetTransferAreasArrayAddrStartMotorExCmd,IsMotorExReadySetOutMotorValues,GetOutMotorValues,SetOutMotorInverseSetOutPwmValues,GetOutPwmValuesSetFtUniConfig,SetFtMotorConfig,SetFtCntConfigGetInIOValueSetSound, IsSoundReadyGetMicLin,GetMicLog
The project to create the static library FtTxtLib and a dynamic link library (DLL) FtTxtLibDll.
The sources Will be come available later.

This PowerShell script takes care for the distribution of the result files from the SolutionTxtLib into SolutionTxtApps.
An introduction about the structure of the transfer area.

The TA communication thread has been moved from the application to the Txt Lib.

Published beta version for RoboPro 4.6.6/4.7.0 pre-release: TXT-C-Programming-Kit-4-6-6_beta-03
- 2020-06-24 [CvL]
Published draft version for RoboPro 4.6.6: TXT-C-Programming-Kit-4-6-6_beta-02
Tested with firmware 4.6.6 and on MS-Windows 10 (64 bits)
Development environment: MS-Visual Studio community 2019,
C++ Dialect: C14++
Added: TestProj02 - example about the use of the enhanced motor control (black box)
with the communication between PC and TXT (TA) as thread.
Choice between Compress mode and Simple as setting.
Test console output conditional with TEST as C++ pre-processor definition.
Renamed FtShmem.h into FtShmemTxt.h, add some TXT related comment.
Limited the TA size to master + 1 slave, this because the TXT can only work with 1 slave.
I2C communication is not implemented yet because the protocol for send and responds the I2C communication is not available.

Note: Don't forget to fill in the right ip-address
Some additional text output for debugging has also been added.
