Tools

Main IDE

(integrated development environment)

Visual Studio (RECOMMENDED)

Free IDE from Microsoft with versatile plugins and collaborative editing.

Workflow:

Create project folder with version control and build system

git init newproject

Prepare the internal file/folder structure

Design Targets

Operating System

Our preferred kernel is Linux and our preferred operating system is Debian. We're fully committed to this open-source kernel+OS ecosystem for all of our CPU/MPU modules. We use real-time Linux for time-sensitive applications.

We use embedded RTOS (ex. FreeRTOS) for our MCU modules.

Error Handling

(monitoring/detection and repair/recovery)

C++ exceptions (pros/cons) traditionally avoided in real-time/critical applications because of insufficient tooling support (ex. Lockheed JSF-CPP Standard) and legacy code non-tolerance (ex. Google CPP Standard).
