Qt for MCUs offers all the necessary tools to design, develop, build, and deploy your application onto the target.

Requirements

Before you begin, install the prerequisites on your Windows host.

Common prerequisites

Install the common prerequisites using Qt Online Installer, which is available for download from your Qt account. Use the pre-made MCU development installation preset and select Renesas RH850-D1M1A in Qt Online Installer:

In addition to the Renesas RH850-D1M1A, the pre-made MCU development installation package installs the following common prerequisites automatically:

• Qt for MCUs SDK v2.8 or newer
• Qt Design Studio v4.4 or newer
• CMake 3.21.1 or newer
• Ninja 1.10.0 or newer

Reference platform -specific tools

In addition to the common prerequisites, install the following reference platform -specific tools as they are not offered by Qt Online Installer:

• Renesas Graphics Library (RGL) v2.1.0a
• Green Hills Software MULTI IDE v7.1.6
• Green Hills Software compiler version 2018.1.5

To use a different Green Hills Software compiler version you will first have to rebuild the Qt Quick Ultralite core libraries, see Building Qt Quick Ultralite from sources for more information.

Tasks

The guide includes several topics, describing the process with step-by-step instructions for the following tasks:

• Design a simple UI using Qt Design Studio
• Develop the application backend in GHS MULTI IDE
  • Export application and platform sources
  • Build application in GHS MULTI IDE
  • Develop the C++ backend
