Talaria TWO MCU Hosted SDKs

Talaria TWO MCU Hosted SDKs

Overview

Talaria TWO supports applications that require an external MCU hosts for additional processing or peripheral interfaces not supported by Talaria TWO. Talaria TWO communicates to the MCU hosts over SPI or UART interface through a series of message exchanges. Talaria TWO offloads the networking & cloud functionalities and peripheral interfaces so that the host MCU can focus on custom logic required for the application. This architecture has the following advantages:

  • Lower Total Cost of Ownership (TCO) - Flexibility to choose the right MCU & memory for the IoT application without having to worry about resources required for networking.
  • Rapid Time to Market (TTM) - Inherit or reuse Talaria TWO SDK certifications in their end product

External MCUs can communicate with Talaria TWO using the following interfaces:

AT Commands

  • MCU host can issue commands to Talaria TWO over the UART interface to perform Wi-Fi & BLE networking functionalities. AT command is driven by a command response state machine that exchanges command and data in ASCII format.
  • Any MCU can communicate with Talaria TWO using this command interface.
  • Talaria TWO SDK supports AT commands and no additional SDK is required to use this interface.
  • This interface can be extended to build custom commands.

Host Application Processing Interface (HAPI)

  • HAPI is a ‘c’ library available on the host MCU that allows the host application to communicate with Talaria TWO over SPI interface. Host MCU will find it convenient to incorporate Talaria TWO HAPI in their application for better programmability and debugging.
  • HAPI is already supported on STM32L4, STM32U5 and Nuvoton M2354 MCUs including reference applications. Additional SDK package required for each MCU host is available for download in the customer portal.
  • HAPI can be easily ported to additional host MCUs
  • HAPI interface can be extended to add custom commands between the host MCU & Talaria TWO.
