User manual
ZigBee
®
dual IF EEPROM adapter for the STM322xG-EVAL
Introduction
This user manual describes the ZigBee
®
adapter for the STM322xG-EVAL needed to
manage a smartplugW network system through the STM322xG-EVAL board. The ZigBee
adapter for the STM322xG-EVAL has been developed in order to interface the STM322xG-
EVAL board with the ZigBee coordinator. The ZigBee coordinator is connected to the
STM322xG demonstration board through the adapter that allows SPI, I²C and UART
communication. The user can properly set jumpers JP3 and JP4 in order to choose how to
communicate between the STM32W and STM32F2xx. The I²C interface is used for the
communication of the STM32W and the dual interface EEPROM onboard. In
, it is
possible to take a quick look at the STM322xG-Eval board and a smartplug node block
diagram. The dual interface EEPROM “M24LR64r” onboard is accessible from both the
STM32W and the STM32F2xx via I²C interface and remotely by means of an RF reader.
Therefore, it is possible to read and update parameters from inside (I²C) and outside (RF)
the application. It therefore allows final application data management:
■
IDentification: read-only unique identifier
■
Traceability: trace code, date, BOM code, etc.
■
Inventory: supply chain visibility
■
Live update: application parameter update
■
Remote activation: code enabler
■
Maintenance: wireless access to events/logs
■
Diagnostics: possible real-time wireless access to parameters
