File: EZ430-RF2500 Wireless Mouse Project

Jaspreet Singh — Sat, 15 Jun 2013 21:06:00 GMT

PROJECT DESCRIPTION

A simple easy to use wireless mouse developed using TI EZ430-RF2500 RF Module. The project is rather simple. All you need is a resistive/capacitive touch screen (I got mine from a mobile repair shop) and the EZ430-RF2500 kit and you are ready to go. I use a coin cell battery (3V) to power the touch screen and EZ430 Target module. The X axis and Y axis data is obtained from the touch screen via A/D conversion using the EZ430-RF2500 module. The data is then transferred to the other target board connected to the Laptop/PC (via a Serial UART interface). The data obtained is then processed via a application GUI which i developed in Visual C# programming language using Visual Studio 2010. The GUI interacts with the windows and generates mouse actions accordingly. The application simulates all mouse actions including the mouse scroll.

I have attached the source code for the Application GUI along with the other download files since you will need to edit certain conditions in the mouse logic code in case you want to make one by yourself. Use Visual Studio 2010 or higher to edit the code.

USER'S GUIDE:

You will need to upload the codes to both the EZ430-RF2500 Target Modules for working with the GUI. The code for the target modules and the GUI Source Code can be downloaded from the link below: (Please visit the site to view this file)

I have tried my best to comment the code properly for those who are new to the MSP430 development environment. You can also view the video for the demonstration of the GUI. The link is embedded in this post.

To upload the code to EZ430 Module, you can either use CCS (Code Composer Studio) or IAR Workbench. I personally prefer IAR Workbench just for this particular module since it's easier to work with the header files in IAR Workbench. You will need to use SimpliciTI Library files for working with the code that i have used. You can download it from here: http://www.ti.com/tool/simpliciti (Download the version for MSP430).

Note: The X-axis and Y-axis data are read via the P3 and P5 pins on the Target module respectively.

For any queries and suggestions, feel free to drop me a mail.

Quick update for everyone:

We received new motors, propellers, and batteries today to help us solve our lift problem. We have moved up to 11.1V 3S batteries, and have new 2900 and 3800 KV motors which should spin a little faster. We will be testing with the smaller two blade props, but if we can't get enough lift from them I also have some new 5030 3 blade props which should give us a little more umph (but will require lengthening the PCB).

Also of note, the motors are a beautiful shade of red and black which mirrors the TI colors.

I'll post another update once we get these guys spinning and quantify the thrust we get.

Baluba,

I actually had that heatsink lying around and just cut it up with a table saw to get the size I wanted. I looked for an appropriate heatsink that I could get in quantity, but it proved difficult to find a good one.

PROJECT DESCRIPTION

A Simple easy to use Wireless Data Logger using TI EZ430-RF2500 RF Module. The data obtained via ADC pins on the EZ430 RF2500 Target Module is available to the user via a Windows based Graphic User Interface (GUI) developed using Visual C#. I was getting emails from way too many people regarding how to work with the EZ430-RF2500 Module. So, i finally decided do one small project.

Forum Post: RE: ADS1293 wireless ECG Stellaris LaunchPad booster board

Hi again

Sorry, I forgot to mention my special interest in your "Digital Signal Enhancement Algorithm" you mention in the slide show. Will you please tell me more about it. I suppose it could be useful when doing FFT and FIR filtering in my battery driven wireless project. By the way, I see no use of LDOs in the schematic named ADS1293 SchDoc dated 3/15/2013. Didn't you use any in your ASS1293 LauchPad Booster Board?

Thank you, Brandon. Glad you like it. I was also thinking about a design for DC motors/steppers that require higher voltage. Even better if they were stackable.

Forum Post: Rover vehicle powered by TI-RTOS

Tom Kopriva — Mon, 08 Apr 2013 08:17:00 GMT

Hi folks,

here's my entry for the Boosterpack contest.

The purpose of "rover" is just to provided a fun platform that can demonstrate TI-RTOS drivers; in particular the I²C, SDSPI (SD card support via SPI), UART, and CC3000 drivers.

As you can see, the rover hasn't been fabricated (as it wasn't a requirement and hence the cardboard mockup :) ) but an example of the TI-RTOS software has already been developed by a former TI intern (Kevin Q.) on his Evalbot Controller (on the left).

The board itself doesn't come with the Tamya tank kit (~$20), but it's been designed to take in flexible range of power supply inputs (3V-16V) so it can work with other chassis. The bulk of the peripherals are I²C peripherals that allow for basic IR object detection, RGB LED indicators, inertial measurements while allowing additional boosterpacks to be added for wifi/bluetooth communications.

TI components:

DRV8801PWPR: Motor Driver
TLC59116IPWR: I2C LED Driver
CSD16301Q2: Power MOSFET
TCA6408APWR: I2C GPIO Expander
TPS62140RGTT: Buck Converter
TL1963ADCQR: Low Dropout Regulator

Compatible with:

Stellaris LM4F120 Launchpad
CC3000 boosterpack
CC3000 LSResearch module
CC2500 Panasonic Bluetooth module

Forum Post: Bluetooth Home Automation BoosterPack

Mark Easley — Fri, 05 Apr 2013 22:28:00 GMT

Description:

This BoosterPack mockup demos how a TI cc2560 Bluetooth module interfacing with LaunchPad can enable end users to control lighting applications with traditional physical actuation as well as digital actuation via a smartphone or tablet app. The software allows you to scan and pair with nearby Bluetooth embedded devices in your home or office and allows you to actuate the integrated solid state relay. This BoosterPack also has the ability to integrate with other components like haptic or capacitive touch elements to enable more modern lighting control user interface and user experience.

This allows a user to control household electric appliances and lighting while seated or on the other side of the room. This is the future of home automation and connectivity. The automated home will require multilayer networking with Bluetooth, WiFi, and Zigbee enabling different applications.

The final BoosterPack would have an integrated cc2560 module, relay or TRIAC, and AC powersupply for drop in, out of box LaunchPad lighting demo. BoosterPack can be configured to support in wall operation for lighting, or smart socket operation for appliances.

Forum Post: SPI Servo Boosterpack

Devin Cottier — Thu, 04 Apr 2013 13:09:00 GMT

Control up to 8 servo motors with your MSP430, C2000, or Stellaris Launchpad. Powered via dual on-board wide input range (6V -20V) 1.5A buck regulators suitable for a variety of power sources including 2+ cell LiPo or other rechargeable batteries. Two auxiliary output channels controlled by N-channel power MOSFET can drive DC peripherals (e.g. solenoid, motor, pump, relay, etc.). Stackable headers allow combination with other boosterpacks or self-stacking up to 4 servo boosterpacks allowing control of up to 32 servo motors.

Featured TI components:

MSP430F5131 (takes SPI / UART commands and generates servo control signals)
LM25011 Buck Regulator x 2 (used to generate servo supply voltages)
LM2842Y Buck Regulator (used to generate MSP430F5131 supply voltage)
CSD16301Q2 Power MOSFET (low-side driver for auxiliary solenoid, DC motor, DC pump, relay, etc.)

Forum Post: TIPhoon Booster Pack

Divya Alok Gupta — Wed, 03 Apr 2013 08:05:00 GMT

TIPhoon booster pack is a an addon to the MSP430 Launchpad. This booster pack provides full flexibility to control 2 types of motors namely the the DC motor and Servo motor. It employs TI's own DRV8800 Motor Controller which caters to all the requirements of a Brushed DC Motor. The Servo Motor is simply controlled by Pulse Width Modulation on a GPIO. The motors can be controlled by using an interactive GUI (designed in MATLAB) which interacts with MSP430 by following the UART protocol. It lets you independently choose the speed, direction and the precise angle through which you want to turn the motors. Not only that, there is also an option of interfacing up to 3 analog sensors with the MSP430 Launchpad. This feature enables the creation of a complete feedback system using Hall Effect sensors or Shaft Encoders or any other feedback control system which in turn makes motor control highly accurate.
