Is there a simple way to have Teensy open and write files on a connected computer, similar to the way Semihosting (http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0471g/Bgbjjgij.html) enables a program running on an ARM device to use the filesystem of a connected computer? This would be helpful for debugging and profiling, or if the Teensy is used to collect data that will be analyzed on a desktop computer.
