Summary of Changes - version 11.4.1 - September 2021

  • Upgraded: Newer SEGGER J-Link software (v7.54b, 32-bit version on Windows, 64-bit version on Linux/macOS).
  • Upgraded: Newer PEmicro plugin (v5.1.0).
  • Added: MCU-Link Pro probe support.
  • Improvement: [SWO/Energy Measurement] Improved data collection rate. This aims to decrease the rate of lost packets (SWO) and gaps (Energy Measurement) at higher speed rates.

  • Fixed: [Energy Measurement] No energy consumption info is displayed when measuring high (> 1W) power.
  • Fixed: [Energy Measurement] No data is displayed after a while when measuring high currents.
