jeffeb3 / .Xmodmap

Created January 29, 2016 00:08

Xmodmap for mimicking pok3r keyboard layer.


	! Trying to F*** with my keyboard.
	!
	! The theory is that if I make the caps lock be the "Mode_switch" key,
	! then I can change what happens for each key when I press the "Mode_switch" key.
	!
	! I'm not using the "Mode_switch" key anyway...
	!
	! This will make the caps lock be the "Mode_switch" key.
	clear Lock

Example for the ESPBackBone library I'm writing

	#include <ESP32BackBone.h>

	double value1(0.0);
	double value2(0.0);

	// Converts the voltage value to 0-100 (used in the display code)

Measure RPM from a piece of tape spinning on a fast thing.

	// These aren't special, just use ints.
	const int IR = 4;
	const int PHOTO = 2;
	// These are coming from the "micros()" function, so that dictates an unsigned long
	volatile unsigned long rpm_value;
	volatile unsigned long prev_rpm_time = 0;
	volatile unsigned long current_rpm_time = 0;

	float rpmmath;
	float smooth_rpm = 0.0; // Be sure you initialize this.

jeffeb3 / median.cpp

Simple functions to calculate medians from doubles.


	#include "median.h"

	#include <string.h>

	// Storage for the input to the median filter.
	double data[MEDIAN_FILTER_SIZE];
	double median_data[MEDIAN_FILTER_SIZE];
	// Pointer to the next element in the median filter. Not very safe programming!
	double* pNextDataInput = data;
