Embedded Artists / lpc4088_displaymodule_benchmark

Program to benchmark the speed of the different file system options versus placing data directly into arrays.

Dependencies:   DMBasicGUI DMSupport

This program is used to measure the performance of the different file system options on the LPC4088 Display Module.

The performance wiki page and more specifically the software part describes this program and the output.

As the program doesn't use the display at all it can be used on both the 4.3" and 5" display modules.
