STM32CubeG0 Nucleo demonstration firmware
Introduction
STM32Cube™ is an STMicroelectronics original initiative to make developers’ lives easier
by reducing development effort, time and cost. STM32Cube covers the whole STM32
portfolio.
The STM32Cube includes:
• STM3
2CubeMX, a graphical software configuration tool that allows the generation of C
initialization code using graphical wizards.
• A comprehensive embedded software platform, delivered per Series (such as
STM32CubeG0 for STM32G0 Series)
– The STM32Cube HAL, STM32 abstraction layer embedded software ensuring
maximized portability across the STM32 portfolio
– The Low-Layer APIs (LL) offering a fast light-weight expert-oriented layer which is
closer to the hardware than the HAL. LL APIs are available only for a set of
peripherals
– A consistent set of middleware components such as FAT file system, RTOS, USB PD
– All embedded software utilities, delivered with a full set of examples
The STM32CubeG0 Nucleo demonstration firmwar
e is built around the STM32Cube
hardware abstraction layer (HAL) and low-layer (LL) APIs, and board support package
(BSP) components, and uses almost the whole STM32 capability to load and display full
color bitmaps from a microSD™ card.
