If your data rate is 20 samples per second. I think that you may use the uart port of microcontroller interface with PC.
Matlab provides serial communication function (MATLAB Central - File detail - MATLAB serial - code example)
and file tools. By the way, I think that LabVIEW is more easy...

Hi all:
ARM is very interesting for me. But I don't know how to setup its coding environment. How do
you download your code to ARM? And how can you step by step debug on ARM? Can I make some simple circuit connected between printer port and JTAG interface of ARM Chip...
Please help me
I think that you can use two wires to do. One for DC
power line, and the another for ground.And then use FSK modem ic to transmit or receive data.
can you mega ohm resistor op amp
I want to design an amplify circuit , and I need about 500M ohm of resistor in my design. But I don't know how to buy it form ? Please tell me the company's name if you know. My E-mail is bearchang@gmail.com . Thank you.
at89c51ac2 circuit
I suggest you can use AT89S51 or AT 89S52 . Because it can support in system program.And use it as use AT89C51.You can find more detail information in website below.
SR and 3dB BW question
If you use operational amplifier work in voltage follower. You maybe can consider high speed operational amplifier. For instance,the LM6172 of National Semiconductor. Its Slew Rate is 3000V/us.
And the 3dB Bandwidth is mean that you can useful frequency range.
avrprog max232 isp programmer
I have a circuit about AVR Programmer. But use the 74HCT541 . I use it download code to AT90S8515 well. It maybe can useful in ATmega series. If you need it . Please give me your e-mail. I will mail to you recently.
My E-mail: bear@zytc.com.tw
Best Regards...
Re: Is 8bit enough?
Maybe you can consider the MSP430 Serise . It have Uart port and 200K Sample rate ADC . And It is 16bits MPU. It is very suitsble your application. You can visit the TI's Web to find it .
Best Regards...
8051 alarm
You can use ultrasonic to detect person . Then connect the trigger signal to 8051 INT pin. When the ultrasonic detect person, will enable the interrupt sub-routine . you can wirte a sample code in this . and the external driver circuit can use BJT in common emitter mode.
USB mass storage help
Please reference the Cypress's EZ-USB Series. I think you cannot use ft2232bm in the mass storage application.
**broken link removed**
You can use 12M Crystal in external Oscillator.Then the internal clock time is 1us/1clock (1(12M/12)).Use the Time0 in Mode 1.Than Set TR0=GATE0=1 and connect probe to P3.2. When the P3.2 is high level,the Time0(Conuter0) will count until the P3.2 change to low level.I suppose the count value is...
