Guiliani:Features

Guiliani is a C++ software framework enabling the creation of visually appealing, hardware and OS platform-independent GUIs for embedded systems.

Guiliani adopts the philosophy of write once, compile for & run on many different target hardware. Once a Guiliani application has been developed, it can run natively on supported target platforms. When using Guiliani, the usual development workflow is to design the application on a PC and target a set of embedded platforms for production release.

Minimum HW requirements

Criteria	Requirements
MCU	100Mhz
ROM	~700kb for Guiliani without resources
RAM	~50kb for Guiliani without resources
Compiler	C++ Compiler with exception Support
Operating System	no Operating System required, but many supported

Architecture overview

Guiliani is split into two layers, the Guiliani runtime engine, and a platform abstraction layer.

Features

System, platform and peripherals

• Object-oriented C++ HMI-framework optimized for embedded systems
  • Low memory consumption
  • Minimized CPU usage
• Operation system independent (Baremetal, eLinux, FreeRTOS, embOS, ARM mbed, ...)
• CPU independent (MCU, MPU, ARM, FPGA with NIOS, ...)
  • Support for fixed point / floating point CPUs
  • So far supported embedded platforms include: i.MX6, i.MX7, Raspberry PI, Renesas RZ/A, RZ/G, RX63N, STM32F429, ALTERA NIOS II, Intel x86,…

• Support for subpixel-accurate rendering
• Support for hardware-specific capabilities (e.g. hardware graphic layers)
• UNICODE support (UTF-8, UTF-16)
• Prepared for thread-safe integration into existing applications

GUI features

• Large set of pre-defined widgets
• Easy to customize existing widgets or to integrate new widgets
• Support for animations
• Multi-language support (dynamically switchable at runtime)
• Image-sets (skinning)
• Automated layout of GUI elements
• Rich text support

ROM/RAM-usage

The following list contains values for the memory-usage of Guiliani in different configurations. of course the actual memory-usage heavily depends on the used features and resources.

All values are determined using the following configuation:

 * GNU Tools ARM Embedded 6 2017 Q2
 * debug-build with -Og
