	WinActivate "BlackBerry Backup Extractor"
	WinWaitActive "BlackBerry Backup Extractor"

	ControlClick "WindowsForms10.BUTTON.app.0.282af8c_r12_ad11"

	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.

Convert bitcoin `nBits` field into a hex string value for `target` using only string functions

	// Returns a 64 char (256 bit) hex string of the target
	// Based on https://developer.bitcoin.org/reference/block_chain.html#target-nbits

	const significand = nbits & 0x00ffffff;
	const exponent = nbits >>> (8*3);

	// (all `*2` are becuase calcuations are in bytes, but in string 1 byte = 2 letter places)

	const fixed6SigString = (significand.toString(16)).padStart( 3*2 , "0");

Example of how to prevent sleeping on a Move38 blink - DANGER: USE WITH CARE

	#include "shared/blinkbios_shared_button.h"
	#include "shared/blinkbios_shared_functions.h"

	// 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.

Counts the number of connected nodes in a distributed and robust way. More info at https://forum.move38.com/t/yadca-yet-another-distributed-counting-algorithm/468

	// 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.
