P08331: Microcontroller Starter Kit
/public/
Home
Project Summary
-
Past senior design teams, when given a project that
requires the functionality of a DSP or microcontroller,
panic. They are unfamiliar with the technologies and
the projects focus turns to controller selection and
implementation rather then the project design.
-
An attempt to alleviate some of the confusion and
panic, project P08331 is tasked to design an affordable
DSP/Microcontroller starter kit. The starter kit will
have a standardized stackable interface for I/O,
automated programming capabilities at the push of a
button or via WiFi web based interface, as well as a
WiFi web based real time debugging interface.
The Design Concept
-
Create a scalable microcontroller platform with the
ability to expand its featureset with future I/O and
probe boards.
-
The Microcontroller board will consist of a TMS320F2809
DSP and a LANTronix wireless webserver, used as a debug
module. The processor will be programmed with RS-232 or
file upload to the aforementioned webserver. The board
accepts 5V and a restricted amount of current,
providing 5V/3A to subordinate boards via power header.
The web interface of the Lantronix device server should
provide a visual representation of all processor I/O
pin states, voltage output of all regulators, total
current draw, as well as a GUI for on board
diagnostics.
-
Provide communication protocols: I2C, SPI,
CAN, & SCI (UART)
-
Provide buffered 1.8V, 3.3V & 5V from a 5V wall
wart via standard power connector, or accept 5V from
power header and regulate down to 1.8V & 3.3V.
