Texas Instruments - Launchpad: The new approach to innovative developement in microcontrollers

Texas Instruments has been working in manufacturing of discrete electronics since a very long time. It manufactures almost all electronic components from comparators to microcontrollers.

A few years back Texas Instruments(TI) launched a new 8-bit microcontroller development platform for hobbyists and new learners. This platform was very low cost and came with basic set of tools to start developing small embedded projects. It was called "The LaunchPad".

Initially an MSP-430 based development board was launched which was priced at $2.99!!

Recently TI has expanded the "Launchpad" line to include boards with C2000 and ARM Cortex Series processors. There are also some new development boards with special interface like USB and Wifi.

There are also a number of plug-in modules available to extend the functionality of your LaunchPad. TI calls these plug-in modules "Booster Packs". There are Booster Packs available for Alphanumeric LCDs, capacitive touch, motors drives and a number of different sensors.

The Launchpad products come with an open-source code editing tool called "Energia" and also TI's own "Code Composer Studio".

Here is an overview of the LaunchPad product line.

MSP LaunchPads

These ultra low power LaunchPads feature the MSP430 miconcontroller and are designed to be battery operated.

C2000 LaunchPads

The C2000 LaunchPads are designed for real-time processing applications. They can be used for 3-phase motor control.

Connected LaunchPads

These LaunchPads are for designs that require connectivity like Ethernet, USB and Wifi. They can be used for Internet-Of-Things (IoT) applications like home automation and smart energy.

Hercules LaunchPads

This series of LaunchPads is for use in development of safety critical equipments like industrial, automotive and medical devices. They feature ARM Cortex processors with lock-step cores and other safety features.

Happy hacking!!

Wireless Door Unlock (TI ZigBee+Accelerometers)

I came across this project by some university students for the TI Ultra low power challenge.
They have used a special wrist watch which contains a TI ZigBee wireless device and accelerometers. They send the unlock code by tapping on the wrist, this tapping is interpreted by the accelerometer, then encrypted by the ZigBee device and transmitted. Another ZigBee device is present inside the door lock, which decodes the encrypted unlock code sent by the watch and then activates the servo to open the lock.

PonyProg 2000 Software for AVR Flash memory

PonyProg is a great software for flash memory programming. It supports a great variety of microcontrollers and other devices. Before using it you should check if your device is supported on the Official PonyProg 2000 Homepage. PonyProg 2000 is constantly updated and new devices are added.

AVR Development boards

A microcontroller Development Board is a generic printed circuit board(PCB), not meant for any specific application. It usually has an interface for programming the microcontroller's flash memory, connectors for the microcontroller's I/O ports, LED banks to show the status of the I/O ports, a reset switch and a serial port or some other comm. port for talking to the outside world. But all this is optional and you can add or remove anything from it depending on your needs or application. Development Boards are very important for hobbyists and small projects.

ISP Flash Memory Programmer for AVR using Parallel port

ISP Flash Memory Programmer for AVR using Serial port

AVR flash memory programmers are easy to build and one programmer can program a virtually program all series and types of AVR devices. This universal compatibility is because of the ISP (In-System Programmable) feature incorporated in almost all AVR devices.

Now there are two three types of Flash memory programmers; Serial, Parallel and USB. I've used all of them so I'll tell you the details about each of them. The software is discussed at the end of the post.

Download Proteus and Keil Development, Simulation and PCB layout Software for 8051

Proteus and Keil are two ideal and sufficient tools for learning and carrying out extensive development on the 8051 microcontrollers. I myself learned 8051 using both these tools so I'll recommend them for everybody. Keil is used to write assembly language or C++ code 8051(although it supports many other microcontrollers) and Proteus can be used to simulate and verify 8051 circuits with pin-point accuracy. This is specially useful for beginners or people who do not know much about hardware or cannot build it for some reason.

GSM Vehicle Control and Security System using SMS

I did this project for my 5th semester for "Microcontroller based Systems". It was done on an 89C51 microcontroller which belongs to 8051 family, using a sony ericsson T290i mobile inter-connected with a serial cable. It was implemented on my Honda Civic.
The user could control some functions of the vehicle by sending
