#128402 - Request for suggestion
hi friends,

i m working on a project thats a data logger.
while working as online, for every second it will send i/p data to the pc through UART....
and i have completed this part successfully....

Now the difficulty is, when the instrument is selected to work as ofline, the data should be written in a memory...
this memory size should be more than 2MB.

i m confused of what type of memory to use....
So please give me suggestions what can i do...

there are some USB Pendrives available in market.. should i use it ? if yes, how can it be interfaced? i m very new to usb.. where can i get its protocol etc...?
i have experience in interfacing through I2C, SPI, UART...

i came to know there are some SRAM availabe having size upto 64Mb.. but those required parallel interface..
i have a UART free, & A 4 port pins free for SPI... i can arrange a SMBUS also if required...

Please suggest me some solution......
thanks.....
best regards,
Anita,
Pune..
