Currently, we use ST’s Standard Peripheral Library (SPL). Goal is to research alternative peripheral libraries and discuss pros/cons of each alternative to see if it’s worth switching.there’s any advantage in switching.

What we currently use SPL for:

• ADC

• CAN

• CRC/RCC

• FLASH

• GPIO

• I2C

• TIMERS

• SPI

• UART

STM32CubeF0

https://github.com/STMicroelectronics/STM32CubeF0

• STM32Cube is an MCU Package provided by STMicroelectronics. Comes with CubeMX (graphical configuration tool), HAL, and other middleware components.

• Pros

  • Lots of documentation/examples

  • Supports a variety of boards https://github.com/STMicroelectronics/STM32Cube_MCU_Overall_Offer

• Cons

  todo

  contains a higher hardware abstraction level so it’s possible we would write less of the HAL code ourselves, although not sure how good it is/how well it fits our needs

• Additional “bloat” compared to the standard peripheral library if the extra HAL features are not necessary

• Standard peripheral library is deprecated in favour of STM32Cube HAL -> https://community.st.com/s/question/0D50X00009XkYd6/stm32l4-standard-peripheral-libraries

• Has lower-layer drivers for more flexibility if needed

libopencm3

https://github.com/libopencm3/libopencm3

• Open-source firmware library for ARM Cortex-M microcontrollers.

• Pros

  • todo

• Cons

  todo

  (not from ST)

• Repo claims that support for STM32F0 boards is “complete”

• Documentation seems little less clear than ST libraries
