11/18/2023 0 Comments Stm32 nucleo bluetooth![]() HAL and LL APIs are available in open-source BSD license for user convenience. Based on an Arm CortexM33 core running at 100 MHz, STM32WBA wireless microcontrollers support Bluetooth Low Energy 5.3 and embed 1Mbyte of flash memory and 128Kbytes of RAM. In addition, the low-layer APIs provide an alternative, high-performance, low-footprint solution to the STM32CubeWB HAL at the cost of portability and simplicity. Following STM32Cube initiative, this set of components is highly portable, not only within the STM32WB Series but also to other STM32 Series. The STM32CubeWB gathers in one single package all the generic embedded software components required to develop an application on STM32WB microcontrollers. Furthermore, STMicroelectornics specific validation processes add a deeper-level qualification. HAL and LL APIs can be used simultaneously with a few restrictions.īoth the HAL and LL APIs are production-ready and have been developed in compliance with CodeSonar ®, MISRA C ®:2012 guidelines and ISO/TS 16949. ![]() The STM32Cube HAL is an STM32 embedded software layer that ensures maximized portability across the STM32 portfolio, while the LL APIs make up a fast, light-weight, expert-oriented layer which is closer to the hardware than the HAL. All embedded software utilities are delivered with a full set of examples running on STMicroelectronics boards. It also comprises the STM32CubeWB MCU Package composed of the STM32Cube hardware abstraction layer (HAL) and the low-layer (LL) APIs, a consistent set of middleware components such as USB Device, STMTouch, STM32_WPAN (Bluetooth ® 5.4 profiles and services, OpenThread and 802.15.4 MAC services), FatFS and FreeRTOS™ kernel, plus Bluetooth ® 5.4 and Mesh V1.0 profiles and services, Zigbee ® 3.0 stack and clusters, OpenThread, Concurrent Bluetooth ® 5.4/Thread ®, HCI and 802.15.4 MAC connectivity services. STM32Cube includes STM32CubeMX, a graphical software configuration tool that allows the generation of C initialization code using graphical wizards. STM32Cube covers the whole STM32 portfolio. STM32Cube is an STMicroelectronics original initiative to make developer' life easier by reducing development effort, time and cost.
