1. Introduction
The STM32CubeWBa MCU Package[1] provides software components running on STM32WBA MCUs.
For all examples provided with the package, the following integrated development environments are supported:
- STMicroelectronics integrated development environment for STM32 products (STM32CubeIDE)
- IAR Systems® IAR Embedded Workbench® for Arm® (EWARM)
- Keil® microcontroller development kit (MDK-ARM)
The Firmware Package for the STM32WBA series is also available on STM32CubeWBA github[2].
2. STM32WBA Zigbee software architecture
The single Core Arm® Cortex®-M33 STM32WBA Zigbee solution is designed to develop application firmware including clusters and smart energy objects on top of the Zigbee Stack and 802.15.4 MAC & PHY, as depicted in the figure below.
| STM32WBA Zigbee architecture |
|---|
STM32WBA5xxG Memory system:
- 1-Mbyte flash memory from address offset 0x00 0000 to 0x0F FFFF
- 128-Kbyte SRAMs:
- SRAM1 64-Kbyte from address offset 0x0 0000 to 0x0 FFFF. (continuous SRAM space with SRAM2)
- SRAM2 64-Kbyte
3. STM32WBA Zigbee applications
The STM32WBA utilizes the Zigbee stack R23, which is available in two library types, FFD and RFD.
ZigBee Cluster Library ZCL8.0 is provided as a library, with the option to receive the source code under a non-disclosure agreement (NDA).
Different operating systems are supported:
- Bare metal
- FreeRTOS
- ThreadX
In order to be compliant with Smart Energy 1.4, STM32WBA will also support Zigbee R22.2.
The following Zigbee applications are delivered as source codes. These applications are available on P-NUCLEO-WBA55 boards.
The purpose of these applications is mainly to provide simple examples that highlight the use of specific clusters.
