The intent of this module is to describe the laboratory equipment and hardware setup at Rice University DSP Laboratory.

Laboratory equipment

Each lab PC is equipped with a Texas Instrument TMS320C6211 DSK board. The DSK board is hooked to the parallel port of the PC running Windows2000; the PC can control the DSK via the development environment called ``Code Composer Studio'' (CCS) developed by Texas Instrument.Currently we use CCS version 2.1. If you have your owlnet account, create the Samba password to log into the machines. If you don't have an owlnet account, the TA will give you a username and password for local log in.

For analog signal input and output, the DSK board has a PCM3003 codec daughtercard mounted on the board.This board provides 16 bit stereo analog input and output channels at maximum sampling rate of 48kHz. Currently, the jumperson the board are configured to provide a fixed 48kHz sampling rate both for input and output. Do not change the jumper settings unless you know what you are doing. For variable sampling rates, the timers of the C6211 processor can be used to generate appropriate clock signal. You willlearn how to use the CPU timers in Lab 4.

Each lab station is equipped with a function generator to provide signal to be used to test your signal-processing algorithms and an oscilloscopeto display the processed waveforms.

The source analog signal also can be generated using the soundcard of the PC and inputto the DSK board for processing. There are two shareware softwares installed on each PC that enables you to use the sound cardas a tone generator and a simple spectrum analyzer. In the lab experiments, you will be using the tone generator to generate white noiseinput to the DSK board and you can watch the spectrum of the DSK output using the soundcard spectrum analyzer.

Hardware setup

The TI DSK board is connected to the parallel port of the PC. The board requires external power supply connected to it.A speaker and microphone can be connected to the board via the two 3.5mm jacks mounted on the daughtercard that are connected tothe PCM3003 codec. The hardware reset button (white) is on the DSK board toenable hardware reset of the board. When reset, the board goes through several steps of self testing and initialization.Please refer to the online help of the Code Composer Studio for detailed board operation. After each hardware reset, the DSK boardtends to lose the connection with the host PC. Therefore, you should close the CCS before performing hardware reset. Be sure to save allthe files before closing the CCS. After the DSK board finishes the reset, start the CCS again.

Be careful when you handle cables, tools, etc, not to short any circuits on the board.

there is no specific books for beginners but there is book called principle of nanotechnology
what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
s. Reply
of graphene you mean?
or in general
in general
Graphene has a hexagonal structure
