However, the moderately high-level APIs provided by the HAL may have extra more features than what you may actually need in some situations.

I think no one wants to spend so much time building a complete software stack for a specific target then it proves the main idea needs more refinement or the target itself does not perform well enough. Especially for projects that fall in the category of “proof of concept”.

Using the STM32 HAL device drivers can be advantageous in so many situations, and help shorten the development time. Hardware Timer Module Configuration Within CubeMX Here is a screenshot for what it looks like inside the interface where we configure the timer module for example. We’ll configure these peripherals and generate the initialization C-Code using the CubeMX software tool. Including Timers, ADC, USART, I2C, USB, DAC, Comparators, etc. In the same manner, there are low-level hardware drivers for almost all the hardware peripherals in the STM32 microcontrollers. It is fully documented and is MISRA-C 2004 compliant. The source code of HAL and LL drivers is developed in Strict ANSI-C which makes it independent from the development tools. They require deep knowledge of the MCU and peripherals specifications.

The LL offers low-level APIs at registers level, with better optimization but less portability.

They hide the MCU and peripheral complexity to end-user.

The HAL offers high-level and feature-oriented APIs, with a high-portability level.

The HAL and LL are complementary and cover a wide range of applications requirements: The LL APIs are available only for a set of peripherals. The low-layer APIs (LL) offering a fast light-weight expert-oriented layer that is closer to the hardware than the HAL. The HAL is available for all the hardware peripherals. The STM32Cube Hardware Abstraction Layer (HAL), an STM32 abstraction layer embedded software ensuring maximized portability across the STM32 microcontroller. The STM32CubeMX, a graphical software configuration tool that allows generating C initialization code using graphical wizards. It provides the developer with all the low-level drivers, APIs, and enables him/her to dedicate most of the effort to develop the application layer and any required middleware. STM32Cube covers the STM32 portfolio of microcontrollers. STMCube ® is STMicroelectronics’s original initiative to ease and accelerate the development cycle of embedded products.
