LBijaminas / lfsr_20bit.c

Last active August 29, 2015 13:56

20-bit LFSR with a verification function to verify that it does not repeat after the period

	#include <stdint.h>
	#include <stdio.h>
	#include <stdlib.h>
	#define MAX_PERIOD 1048575

	void generateNums(int *);
	void checkDups(int *);
	int main(){
	int genNums[MAX_PERIOD];

LBijaminas / pi_calc.c

Created October 23, 2013 22:52

Simple function to approximate the value of pi.

	#include <stdio.h>
	#include <time.h>
	#include <stdlib.h>

	int main(void) {
	double x, y, i; // variables
	double N0 = 0, Ntot = 100000000; // numbers that the numbers in the range and total numbers
	double A; // area var

LBijaminas / hex_to_str.c

Last active December 23, 2015 03:39

C function to convert hexadecimal number to string. I was looking for it for the kernel I'm trying to make but couldn't find it, so wrote one myself. Hope this helps somebody.

	char checkTheBits(unsigned char hByte);

	char* hex_to_string(unsigned int n){
	// output hexadecimal chars

	unsigned char* location = &n; //get the location of the hex number
	char value[9] = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}; // init null byte array
	// array has 9 values, because last one reserved fur null terminator
	unsigned char temp_char_l, temp_char_h; // temporary vars
	int i = 0, j = 7; // start at 7, because tested on little endian machine
