1 / 40 page  September 2012 Doc ID 022813 Rev 2 1/40 UM1519 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 Figure 1, 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 Figure 1.
