Description

This repository maintains the MT3620 M4 driver and real-time application sample code, which divided into the following directories:

• MT3620_M4_BSP/
  • This folder includes the CMSIS-Core APIs and the configuration of interrupt vector table.
  • Current BSP supports Bare Metal and FreeRTOS.
• MT3620_M4_Driver/
  • The MT3620 M4 driver provides the APIs to access the peripheral interfaces, ex GPIO / SPI / I2S / I2C / UART...
  • This driver could be divided into two layers
    • Upper layer: M-HAL (MediaTek Hardware AbstractionLayer), which provides high-level API to real-time application.
    • Lower layer: HDL (Hardware Driving Layer), which handles the low-level hardware control.
• MT3620_M4_Sample_Code/
  • This is the executable CMake project sample code which utilizes the M-HAL APIs to access the peripheral interfaces.
  • Both Bare Metal and FreeRTOS sample code are included.

Please refer to the MT3620 M4 API Reference Manual for the detailed API description.
Use of the real-time cores is currently a Beta feature.

Prerequisites

• Hardware
  • AVNET MT3620 Starter Kit
  • or Seeed MT3620 Development Kit
  • or other hardware that implements the MT3620 Reference Development Board (RDB) design.
• Software
  • Refer to Azure Sphere software installation guide.
  • A terminal emulator (such as Telnet or PuTTY to display the output log).
