Projects Executed

Title: "Audio Alarm System"

Languages: EMBEDDED C.

Tools Used: ARM Cross Compilers, JTAG debugger

This project is designed on LM3S9B92 microcontroller which is based on ARM

cortex M3 processor. Also uses TLV320AIC32 audio codec hardware which has

the features such as, Programmable input/output analog gain, Automatic gain

control for record, Programmable Microphone bias level and programmable PLL

for flexible clock generation. UART, I2C, I2S and SPI used as communication

interfaces between peripherals.

Role:

. Developed firmware part for Audio Alarm system.

. Involved in coding the Device Driver part for TLV320AIC32 codec

hardware and Flash hardware.

Title: "Simple Boot Loader Development for Launching Embedded Linux

On ARM920T board"

Language used : Embedded C, ARM assembly coding.

Tools Used : ARM Cross Compilers, JTAG debugger, OpenOcd

The main idea of Developing boot loader is to perform boot strapping which

is developed in Machine Specific(ARM9TDMI) ASSEMBLY Code, Configuring the

ARM920T controller, such as, Creating Exception Vector tables, configuring

the cache (D-cache, I-cache), Memory management unit(MMU), Memory

Controller(NAND Flash, SDRAM), Peripherals and launching the Embedded linux-

2.6.32.2

Other Projects

Title : "Automatic Highway Signaling System Using RF"

Language used : C

This project is based on wireless communication technology. It is made

using P89V51RD2 Microcontroller. There are two parts in this project namely

transmitter part and a receiver part. The transmitter part is placed along

the highways to convey information, which is done by using a RF

transmitter. At the receiver part the module is fixed in the Vehicle. This

module consists of a microcontroller connected to a RF receiver, Display

Unit and a buzzer. Whenever the receiver module comes into the visibility

of transmitter it receives the message and displays it on the screen and

buzzer will beep to intimate that the system got a new message. Embedded C

is used for programming the application software to the microcontroller and

Orcad schematic software is used for designing the circuit diagram for this

project.

Title : "Implementing Peripherals using 32-bit ARM

Microcontroller"

Language used : Embedded C.

In this project, an industrial specific 32-bit microcontroller (ARM) is

used to implement the on-chip peripherals like RTC, GPIO, and UART. The

Advantage is that, to develop any project if we use all these peripherals

external then different types of supply voltage is required, PCB board size

and circuit size increases, program size increases etc.
