Microchip J-32
J-Link - Support for Microchip J-32
Overview
Microchip J-32 supports all 32-bit Microchip devices that are supported by SEGGER's J-Link BASE.
J-32 works with Microchip microcontrollers only. This limitation can NOT be lifted; if you would like to use J-Link with a device from a different manufacturer, you need to buy a separate J-Link. No licenses are included.
Non-commercial/educational and paid-for commercial software utilities for J-32
Embedded Studio Powerful C/C++ IDE (Integrated Development Environment) for embedded systems. It is specifically designed to provide users with everything needed for professional embedded C programming and development:
An all-in-one solution providing stability and a continuous workflow for any development environment. Works with all of Microchip’s Arm Cortex-M0, M1, M3, M4, M7 and RISC-V based processors.
SystemView: Live visual analysis of captured tasks, interrupts, timers, API calls and user events. It has minimal system impact and works with all of Microchip’s Arm® Cortex®-M0, M1, M3, M4, M7 and RISC-V based processors.
J-Scope displays runtime data of multiple variables in an oscilloscope format. Simply connect the J-32 Debug Probe to your target, program and start J-Scope.
Each variable can be individually manipulated with familiar oscilloscope controls and features. J-Scope also has minimal system impact and works with all of Microchip’s Arm Cortex-M0, M1, M3, M4, M7 and RISC-V based processors.
Remote Server allows the J-32 Debug Probe to debug from anywhere in the world. This is especially useful when your software expert needs to resolve development or product issues in another region. Remote Server works on all of Microchip’s 32-bit MCU and MPU products.
J-Mem permits direct RAM and Special Function Register (SFR) modifications without a bulky Integrated Development Environment (IDE). Memory can be displayed in an 8-, 16- or 32-bit format and can be exported to a .bin file.
J-Mem is compatible with Windows®, macOS® and Linux® operating systems. J-Mem works on all of Microchip’s 32-bit MCU and MPU products.
