Introducing the new Real-time Watch

One of the toughest types of problems faced by embedded software developers is timing problems. Seeing what exactly happened before a problem popped up and being able to put multiple events on one scale could save hours of time. The previous version of VisualGDB included an embedded profiler that could collect statistics on the runtime of various functions. VisualGDB 5.2 takes this even further and introduces Real-time watch – a framework for convenient recording and visualization of various real-time events in your program that works out-of-the-box with FreeRTOS and supports non-RTOS environments as well:rtw

The New Dependency View in Embedded Memory Explorer

Embedded Memory Explorer is one of the most loved Embedded features of VisualGDB. It helps you keep track of the FLASH and RAM used by your embedded project so you can be sure that your program fits into your device memory:memexpThe new VisualGDB 5.2 comes with a feature that makes this window even more efficient at finding out why is your program bigger than you wanted it to be.

The New Advanced Memory Window in VisualGDB 5.2

One of the topics that got us a lot of feedback recently was the poor performance of the Visual Studio Memory window with embedded VisualGDB projects. Two main problems reported by our users were lack of memory view when the program is running and the fact that it tried reading a wider memory area that was actually displayed, sometimes causing the underlying tools to crash. We have solved that in VisualGDB 5.2 with a brand new Advanced Memory Window specifically designed for maximum usability with VisualGDB projects.mem1

Extending the VisualGDB Test System

The new system for running C++ Unit Tests added to VisualGDB 5.2 has out-of-the-box support for CppUTest and GoogleTest framework. But it’s also designed to be easily extendable to support any other test framework through a flexible set of rules defined in XML files. This post will describe how the test frameworks are defined and what can be customized in the framework definitions to support more frameworks.

The New Unit Test Support in VisualGDB 5.2

One of the new features introduced in VisualGDB 5.2 is the seamless integration of C++ unit testing frameworks into Visual Studio. VisualGDB supports the CppUTest and GoogleTest frameworks for Linux, Android and Embedded projects out-of-the-box and also comes with a powerful customization mechanism that allows describing any other test framework in a way that will allow VisualGDB to discover and run tests from it with just a few mouse clicks.

VisualGDB 5.0 Beta 3 is out

We have released VisualGDB 5.0 Beta 3! This release focuses mainly on usability features for embedded projects that have been requested by the community.

First of all we have added support for live variables – a convenient way to inspect the global variables in your program without stopping it. VisualGDB supports real-time plotting, data breakpoints and can export the data to CSV:livevars

About Android toolchains and system images

Native Android debugging has always been somewhat tricky. In addition to common source path issues and random gdbserver failures, many VisualGDB users reported that they can debug code on their device only if they use certain versions of NDK toolchains. To figure it out once and for all we have added a VisualGDB feature that allows testing a certain Android device with all the toolchains available in the NDK. To get a general overview we have tested the standard ARM emulator images that come with the Android SDK.
