Hey i am using arduino duemilanove (atmega 328P). I am using 16 bit ADC interfaced with SPI protocol and then sending data serially into my laptop(reading com port using matlab). problem is I am getting too few samples. I am expecting 500 samples per sec. So Now I want to store data into arduino memory(flash or EEPROM or RAM). EEPROM I checked it takes 3.3 ms to write 8 bits of data which will lead to loss of data as I am expecting 16 bits every 2ms. Is Flash too that slow? I can write to flash using progspce library.
Also note i will be gettting total of 1000 samples per second( 500 for 1 channel 500 for other)
thanks in advance
