Hi,
I am Optoelectronics engineer, so I need some help with the electronic part of my project.

I have laser pointing at photo-diode(detector), and I need to measure the current its generate (because of the laser beam) in frequency of 10KHz for 2 second. That means that I need the data of 20K measurements. I need this data saved in a computer in order to process it later.

Is there a way of doing it?

I use Keil and Realtime programms.

thx for the help!!!!
 

Take a look at the STM32F4DISCOVERY Discovery.

It has 192K RAM. The board is very inexpensive.

I'm not sure if its supported by the compiler and OS you have... you could use ChibiOS/RT and Sourcery Codebench from Mentor (both are free $0 )
 
ok, I will check it out. thx ^^
Can some1 help me with the function that I need to burn on it to get the data? ( prefer with C ).
 

Well you can use a python script to read the data from an oscilloscope directly and write it to a .dat file. You will not need any controller for that. You can also set the triggers from the scripts.
