TX and TXT with i2c

[Mark010]

Hi, I have connected 3 TX controllers and 1 TXT controller via USB within RoboPro. I can run both the TX and the TXT commands in 1 program. But what I am unable to do, is gettting the i2c displays I have working. Both the TX and the TXT are set as the main controller and I suspect that something is going wrong there, but you have to set it this way otherwise you cannot operate them in 1 program (In Online mode).

Does anyone have an idea if it is possible to get the i2c displays working in this setting? If I only use the TX controllers, with the FT-extender, the displays work fine.

Thanks in advance!

Hi Mark,

Could you please share more details how you connected the TXTs with each other?

Do you use the extension port to connect some slave TXTs to a master and did you connect the master to your PC?

Or do you connect all TXTs to the PC and there is no interconnection between the TXTs.

Did you ever tried to run your program in offline more / without a PC connected?

Best regards

Stefan

Hi Stefan,

I connected the 3 tx controllers (1 master, 2 slaves) with cables with each other via the EXT port. Also on the TX Master i have connected the FT-extender. The master is connected via USB on my PC.
The TXT is also connected on my PC with USB.

This works well, i can run all programms in online mode and in Offline mode. When i have not connected the TXT, so just a program for the 3 TX controllers, the I2C displays work fine in online (for testing, slow) and in download (quick).

Only when i add the TXT, the i2c display don't respond/work. Maybe because there is one TX in master mode and one TXT in master mode at the same time?
