How-to Install UGS (Universal Gcode Sender) and Candle (With Compile on Linux)
I had a request in the comments on my Youtube page, from a post of five months ago. A viewer requested a step-by-step on installing UGS (Universal Gcode Sender) and Candle (Another controller for a GRBL CNC machine.)
My main focus in this video is Linux, Candle required compiling. For some reason, the binary would not run correctly.
I also show how to install both on Windows 10.

BN-880 GPS\Compass Module - The Compass
Let's tackle the compass module of the BN-880 Gps/Compass Module.
The Code:
#include <Arduino.h>
#include <Wire.h>
#include "HMC5883L_Simple.h"
#include <U8g2lib.h>
#include <SPI.h>
#include <TinyGPS++.h>
#include <SoftwareSerial.h>
// Create a compass
HMC5883L_Simple Compass;
// The TinyGPS++ object
TinyGPSPlus gps;
U8G2_ST7920_128X64_1_SW_SPI u8g2(U8G2_R0, 13, 11, 10, 8);
static const int RXPin = 4, TXPin = 3;
static const uint32_t GPSBaud = 9600;
char zs[32] = "";
int x = 0;
int y = 0;
// The serial connection to the GPS device
SoftwareSerial ss(RXPin, TXPin);
void setup()
{
Serial.begin(115200);
ss.begin(GPSBaud);
Wire.begin();
u8g2.begin();
u8g2.clearBuffer();
// Magnetic Declination is the correction applied according to your present location
// in order to get True North from Magnetic North, it varies from place to place.
//
// The declination for your area can be obtained from http://www.magnetic-declination.com/
// Take the "Magnetic Declination" line that it gives you in the information,
//
// Examples:
// Christchurch, 23° 35' EAST
// Wellington , 22° 14' EAST
// Dunedin , 25° 8' EAST
// Auckland , 19° 30' EAST
//
Compass.SetDeclination(1, 40, 'E');
// The device can operate in SINGLE (default) or CONTINUOUS mode
// SINGLE simply means that it takes a reading when you request one
// CONTINUOUS means that it is always taking readings
// for most purposes, SINGLE is what you want.
Compass.SetSamplingMode(COMPASS_CONTINUOUS);
// The scale can be adjusted to one of several levels, you can probably leave it at the default.
// Essentially this controls how sensitive the device is.
// Options are 088, 130 (default), 190, 250, 400, 470, 560, 810
// Specify the option as COMPASS_SCALE_xxx
// Lower values are more sensitive, higher values are less sensitive.
// The default is probably just fine, it works for me. If it seems very noisy
// (jumping around), incrase the scale to a higher one.
Compass.SetScale(COMPASS_SCALE_400);
// The compass has 3 axes, but two of them must be close to parallel to the earth's surface to read it,
// (we do not compensate for tilt, that's a complicated thing) - just like a real compass has a floating
// needle you can imagine the digital compass does too.
//
// To allow you to mount the compass in different ways you can specify the orientation:
// COMPASS_HORIZONTAL_X_NORTH (default), the compass is oriented horizontally, top-side up. when pointing North the X silkscreen arrow will point North
// COMPASS_HORIZONTAL_Y_NORTH, top-side up, Y is the needle,when pointing North the Y silkscreen arrow will point North
// COMPASS_VERTICAL_X_EAST, vertically mounted (tall) looking at the top side, when facing North the X silkscreen arrow will point East
// COMPASS_VERTICAL_Y_WEST, vertically mounted (wide) looking at the top side, when facing North the Y silkscreen arrow will point West
Compass.SetOrientation(COMPASS_HORIZONTAL_X_NORTH);
}
// Our main program loop.

So, I finally got around to getting a memory card for this, I should've done it sooner. Oops.
Nothing against the company, I was being slow.
