J-Mem
Display memory contents of microcontrollers
- Inspect and modify RAM contents
- Access special function registers (SFRs)
- Monitor memory changes in real time
Overview
J-Mem is a small stand-alone application for Windows, macOS, and Linux that allows developers to view and modify target memory using J-Link or J-Trace.
Memory can be accessed in 8-, 16-, or 32-bit units. J-Mem also supports modifying special function registers (SFRs), allowing changes to be applied only after the complete register value has been entered.
Key features
- RAM can be modified
- Special Function Registers (SFRs) can be written
- Whole regions in RAM can be filled with a desired value
- Memory sections can be saved to a .bin file
- A periodic refresh of the displayed memory contents can be set
Licensing
J-Mem comes as part of the J-Link Software and Documentation Package. The software package is free for any J-Link or J-Trace device and can be downloaded here:
