Logging 40,000 Samples/Sec to a SD!

[fat16lib]

The new version of SdFat will have features to log data at higher speeds.

Here is a plot of a 1 kHz sine wave logged at 40,000 samples per second.

The waveform was digitized with a 12-bit MCP3201 ADC and logged as 16-bit binary data to a file using an Adafruit Data Logging Shield.

Would you use this capability?

I plan to include an example program to read the file on a PC/Mac since the file is binary. What language would be best for the PC part of the example? I am considering Java, Perl, or Python.

The files are very large since they are written at 80 KB/sec or 288 MB/hour.

Hi, I will certainly try this out - I have a couple project ideas this will tie-in nicely with.
When are you planning to release it ?

I would think of the three choices Java is the most universal.
