lauterbach-trace32-pystart

Since 2020, Python programs can control TRACE32 via the lauterbach-trace32-rcl module (pyrcl). Up to now, TRACE32 must be started using a config file, which requires familiarization with the TRACE32 configuration file syntax or the use of the configuration tool t32start.exe. Now Lauterbach offers a new lauterbach-trace32-pystart module (pystart) which allows the configuration and start of TRACE32 directly from Python.

For feedback and questions, please contact support@lauterbach.com (include "pystart" in the subject).

Example

import lauterbach.trace32.pystart as pystart

pystart.defaults.system_path = r"C:\T32"

powerview = pystart.PowerView(pystart.USBConnection(), "t32marm")
powerview.title = f"TRACE32 PowerView for ARM 0"
powerview.id = "T32_arm0"

powerview.start()
powerview.wait()
