Getting Started

Installation (for Windows 10)

DSView

Copy the Infineon decoder directory to C:\Program Files\DSView\decoders

e.g. to install Infineon Trust M decoder in DSView copy the directory ifx_trustm into C:\Program Files\DSView\decoders

PulseView

Copy the Infineon decoder directory to C:\Program Files (x86)\sigrok\PulseView\share\libsigrokdecode\decoders

e.g. to install Infineon Trust M decoder in PulseView copy the directory ifx_trustm into C:\Program Files (x86)\sigrok\PulseView\share\libsigrokdecode\decoders

sigrok-cli

Copy the Infineon decoder directory to C:\Program Files (x86)\sigrok\sigrok-cli\share\libsigrokdecode\decoders

e.g. to install Infineon Trust M decoder in sigrok-cli copy the directory ifx_trustm into C:\Program Files (x86)\sigrok\sigrok-cli\share\libsigrokdecode\decoders

Testing with DSView from DreamSourceLab

Open the DSView software, under file and open a sample signal .dsl file. If the decoder is install correctly you will be able to see the decoder name. Select the decoder require and assign the necessary signal channel.

Testing with PulseView from sigrok

Open the PulseView software, Click on open and open a sample signal .sr file. If the decoder is install correctly you will be able to see the decoder name. Select the decoder require and assign the necessary signal channel.

Testing with sigrok-cli

Open the sigrok command-line tools with a command shell. If the path is set correctly you should be able to run the sigrok-cli.exe and it will display the help menu.

To test the command line to with the decoder using a signal file .sr. Run the command below. The output will be pipe to teset.txt.

C:\sigrok-cli -i trustm_chipinfo.sr -P ifx_trustm:scl=SCL:sda=SDA -A ifx_trustm=apdu-cmd:apdu-param:apdu-len:apdu-data-r:apdu-data-w:apdu-err --protocol-decoder-samplenum > test.txt

To list the available decoder annotation run the following command:

sigrok-cli -P ifx_trustm --show

Known issue

Only tested on Windows 10

The decoder is only tested on Windows 10. But it is assume working for the rest of the OS as long as the DSView or PulseView software support it.

Not complete protocol is implemented

Some of the protocol like the ifx-i2c is not completely implemented.

Stack Decoder not supported

The decoder is does not support stack decoder features
