Tracii 400 provides a buffer of 32kB for I2C-bus data. If the "Time Stamp" option is enabled the buffer is reduced to 10.6 kB. In case you have Tracii 400 stretching the I2C-bus because the buffer is too small disable the "Time Stamp" option.

More and more applications require an I2C bus voltage of 3.3V or even lower. Tracii XL is the first choice when working with low bus voltages. Alternatively, Connii and Connii MM are also capable of supporting 3.3V applications.

Please note that

I want to test my I²C-bus environment with high traffic but there are delays between the messages that I have sent with Tracii 400. How can I reduce the delay between the messages?
Before Tracii 400 can send the message they must be transmitted from the PC to the hardware via the parallel port. I...

If I have stopped the application in the debugger the LPT port is locked. What can I do?

The parallel port is locked for other applications after the board was initiated.

If you stop the application in the debugger the port is still locked.

To unlock the port you can reboot the PC or stop and...

The I²C-bus format provides 7 and 10 bit addresses (see also in the I²C-bus specification). In Tracii Talk the addresses are always specified in one value although the I²C-bus transmits one byte for the 7 bit addresses and two bytes for the 10 bit addresses. All addresses >=100h are 10 bit addresses...

I want to trace the I²C-bus data with Tracii Spy and evaluate the data with another application. Does Tracii-Spy offer an interface to get these data?

No, but it is possible to write the data into a log file (Menu: "Settings/LogFile") in ASCII format. This file can be imported by another applic...

For these dialogs Tracii Spy uses controls that must exists and must be registered correctly! Please check in this windows system folder if the files "TraciiDeviceInput.ocx" and "TraciiFilterInput.ocx" exist. If not, please reinstall Tracii Spy or else try to register the files: "regsvr32 <FileName....
