Introduction
MediaTek LinkIt™ for real-time operating system (RTOS) is a low-cost and easy to use Internet of Things (IoT)
development platform to design, prototype, evaluate and implement IoT projects. The platform supports LinkIt™
76x7 hardware development kit (HDK) by SAC. This user manual provides required knowledge on features of the
HDK, including the pins, communication interfaces, core microcontroller unit (MCU) description, the networking
capabilities and how to use them through the host driver. The HDK includes MediaTek MT76x7 chipset which is
based on ARM Cortex-M4 with floating point MCU in QFN68 package. It enables rich connectivity features,
communication with cloud services and real-time control. LinkIt 76x7 HDK is pin compatible with Arduino UNO R3.
MT76x7 product portfolio includes MT7687F, MT7697, and MT7697D. The examples in the document are carried
on MT7687F chipset and could be applied to any MT76x7 based HDK.
The LinkIt 7687 HDK supports ARM
download operations.
The following features are available:
•
Mass storage device (MSD) programmer.
o
The LinkIt 7687 HDK has three binary files for bootloader, Wi-Fi and FreeRTOS. The MSD
programmer enables to update the FreeRTOS binary file only.
•
CMSIS-DAP
(Coresight Debug Access Port (DAP)) Debug Interface.
o
A firmware debug interface similar to
downloading a binary to the flash storage of the device.
•
Virtual Serial Port.
o
Supports UART functionality, such as transferring log information from the HDK.
These features are used to download and debug the project.
