REM Move all of the files from a recently inserted USB drive to a directory on a local hard drive. 

REM Edit these to set the correct paths for your USB drive and the location where you want the files to end up. 
set "SRC=J:\RECORD"
set "DST=D:\Users\josh\Documents\OrsonEar"

REM This should be set up inside Task Schedualer to run on the follwoing event:
REM Log : Microsoft-Windows-DeviceSetupManager/Admin
REM Source : DeviceSetupManager
REM Event ID : 112

VOR=0   (Voice Activation On=1; Off=0. I prefer continuous capture. Bits are free.)
LED=0   (Led On after 10 Sec=1; Led Off after 10 Sec=0. I turn the LED off to save battery and not be anoying in the dark)
SEG=300   (File Segment Time=1~999, I use 300 mins=5 hours per segment)
TIME=20231121181704   (Set this to the current time before saving the file. I use GMT)

/*
 * Below is a a modified version of the TI MSP430 LCDE_01 example named `msp430fr413x_LCDE_01.c`
 * It simply displays the numbers 1-6 on the built-in LCD display on the MSP-EXP430FR4133 Lanuchpad.
 * 
 * I could not find any ultra-low power examples of an MSP430 driving and LCD, so I started with 
 * the TI code and kept updating it to try to use less power using things I noticed in the datasheets.
 * 
 * I was able to drop the current usage from 200uA down to less than 1uA without any noticable change in functionality.
 *
 * I hope to write a full article about this and other MSP430 power optimization techniques on josh.com soon.

// Example of how to prevent a blink from going to sleep.
// This will keep blinking once per second until the battery goes dead. 
// Button click will show a red flash. Note that we are making fake button presses
// to avoid warm sleep, so you can not reliabily detect an actual button press but you can
// see clicks and long presses.

// SimpleCounter demo
// A simple distributed counter example
// 
// On startup, blinks are dim BLUE which shows they are in IDLE mode waiting for a master
//
// Button press a blink to make it master of the cluster. The master will show the current count
// using the 0-342 display format decribed below under showNumber()...
//
// While a blink is actively part of a counting cluster, it will show dim GREEN on the face
// that points to its parent. All parent faces eventually lead back to the master. 

bigjosh

// Display a number 0-342 on the LEDs
// The number is shown in base 7 format with red, green, 
// and blue being the 1's, 7's, and 49's places respecitively
// A 0 digit is shown as OFF. Digits 1-6 are shown as 1-6 LEDs
// lit with the place color. 
//
//   0 = All Off
//   1 = 1 RED
//   2 = 2 RED
//   ...

   Validation Test for Dev Kit Blinks

   4 modes for testing
   1. Verify RGB on all 6 faces together
   2. Verify RGB on each of the 6 faces individually
   3. Verify communication w/ awake neighbors
   4. Verify cold sleep (<0.2µA)
