This is for experienced designers and will allow them to work with the ARM Cortex-M microcontrollers (MCUs) down to register-level code, to controlling device peripheral and to optimise performance and run-time efficiency.

The LL APIs are integrated into the STM32Cube packages with example projects designed to run on STM32 Nucleo development boards.

The LL APIs can be used in parallel with the corresponding hardware abstraction layers (HALs) in the same project, making it possible to trade-off between project time and performance parameters such as software footprint, and run-time efficiency.

Like the HALs in each STM32Cube embedded software package, the LL APIs are MISRA-C 2004 compliant with a few exceptions that are fully listed and explained… Read Full Article at Electronics Weekly
