产品概要
描述
STSW-L9988 is a PC software package for the evaluation and control of the L9988 system board.
Through an intuitive GUI, the user can configure and monitor the device either via a dedicated application interface or directly via the register map view.
The main window provides dedicated tabs to:
- Configure and monitor voltage and current conversion routines, Coulomb counting and cell balancing
- Control the functional state machine and HS pre-drivers, while visualizing key diagnostic information
- Adjust thresholds, filter times and other configuration parameters
- Access and edit RAM and NVM registers, including failure bit indication
Additional windows extend the GUI functionality:
- A register selection window for periodic readout of user‑selected device registers
- A communication interface selector to choose the link between PC and MCU (e.g. COM port, Bluetooth)
- A communication history form to inspect recent communication messages between GUI and MCU
- A powerful script editor that enables users to build and execute command sequences, automate repetitive tasks and evaluate MCU responses, with optional offline execution for accurate and fast timing.
The GUI also supports automatic saving and restoring of the communication and diagnostic refresh configuration, simplifying repeated evaluation sessions of the L9988 system board.
