STM32 serial wire debug viewer
Application developers using 32-bit STM32 take advantage advanced debugging features such runtime trace thanks Serial Wire Debug (SWD) Serial Wire Viewer (SWV), which becoming available major toolsets this ARM® CortexTM-M3 core based family. addition standard stop/go debug controls provided common JTAG-based tools, solutions with provide more information about exactly application executes with advanced features such runtime trace, logic analyzer, program event counters. addition, these additional features require fewer pins target STM32. With these advantages, wonder that leading tool solutions such Keil's RealViewMicrocontroller Development STM32 adding functionality added cost their current users.

Advanced debug viewer features using fewer target resources
Fewer resource requirements
require only three pins target microcontroller offer debugging features that unmatched standard JTAG debugging solutions that require five pins target. This adds more resources application fewer connections application board and, therefore, less board space.
Master 32-bit complexity
With common JTAG based solutions, developers follow execution application from point another code without knowing exactly what instructions executed often. Often this type stop/go debug that required simple applications. With computing power integration STM32 comes challenge mastering increasingly complex software applications that manage increasing variety communication interfaces, microcontroller states application functionalities. conjunction with helps reduce timeto-market allowing developers exactly which instructions executed when running application, thereby reducing guess work finding errors. this, they embedded STM32 resources gain real-time access system memory during execution without halting device's core. allows tools recover information about what instructions executed often. Integrated development environments display this information configurable trace finding software bugs, profile application execution help eliminate bottlenecks execution unused data.
