- by default, all projects are packaged with RTOS support
- project annotated with a (*) are available with and without RTOS support
• Projects folder provides different application examples in which each
project name is prefix with MCU name:

• Project name is build as: MCUname_shieldref_TypeCrole_type
Projects can be compiled with either:
• IAR 8.x,
• GCC using GNU Arm Embedded Toolchain (version used: 9 2020-q2-update with GNU make-4.3),
• STM32CubeIDE (download here).

Type = ONLY
• Those projects are simple ones. Only mandatory features are present, with RTOS
Type = ONLY_noRTOS
• Those projects are simple ones. Only mandatory features are present, without RTOS
Type = VDM
• Those projects are complex ones. Lot of optional features are present and could be
disabled/enabled by compilation switch
Type = SRCING_DEVICE
• This project is DRP sourcing device: application always try to achieve power role as
source and data role as UFP
