Some simple filtering is probably needed to get rid of single jumps that you always get with poor gps signal. You could eg. take 5 samples, discard the extremes and take the average of the 3 mid values. You can add a condition like min 4-5 satellites to discard anything with very poor value (and/or require some value for HDOP).

Cool little device- thanks for sharing! Looking at your footage- you might want to tune your PIDs though?

I have also had this problem with these screens. I remedied this by drawing a small black box over only the area that will be updated instead of redrawing the whole screen. This allowed me to show sensor data from in multiple places on the screen that would update many times per second as well has have moving graphics and animations. 1. Create a static text field: "GPS: " 2. Change "updateScreen()" to something like: display.drawRect(x,x,x,x, BLACK); display.setCursor( just after static line "GPS: ") displayln(gpsVariableData) 3. Repeat as necessary for each variable as necessary and you can still call them simultaneously from updateScreen() and it will be many times faster than redrawing the whole screen.

awesome that you put a direct link to the zip file. Thank You. Trying this soon.

i guess that gives a rough answer to the "how far can it go?" question too. If a battery lasts about 10mins you'd get around 10 to 20km of range (autopilot permitting)

Could you use nested interrupts and set the gps to a higher priority than the screen?

Top questions asked by strangers going by: 1) how far can it go? 2) how high can it go? 3) does it have a camera? 4) what did all of this cost? 5) how long can it fly with one battery? 6) how fast can it go?

Hi, I'm going to build this gps but I want to know how mush accurate is this?

Hi, thanks for the video. As a beginner amateur Arduino programmer.... I am trying to figure out how to log the 1 Hz binary messages to SD card for viewing or processing later. Have you done this? all the tutorials are how to log the parsed NMEA data but would like the raw binary for efficiency.

Hello, and thanks for the awesome work. I have troubles in finding GPS neo-M8N modules with flash memry so you can update firmware. You pointed a Bangood link in the header of the video, but it is broken. Can you share us a link to recommended sellers ? thanks again

is it possible to detach the screen and make it wirelessly?

Hello. What GPS module do you use?

Witch GPS are you using. The link is not working aneymore. I like to build one. gert-jan

Hello Thank you this helped me a loot I do want ask if you can help me more I have looked at the other vids but can get the awnser I want to record the max altitude also but cant seem to figure it out please can you help I am using your code in this project

hello i'm trying to do this project but i don't have any gps signal, the arduino at this moment only gives me a height value but it doesn't mark any speed or satellites.... i'm using a beitian bn220 gps..... which can be failing? Thank you

I think You should anyway try interrupts for receiving GPS packets without loseing data, especially on 10 Hz. For graphic LCD - u8g library. The same screen (also I2C, mini pro 16 MHz) is enough fast for simple graphics animation then there is something wrong (slow) with I2C in this sketch.

1) is this a drone? 2) how much does it cost? 3) how far can it fly? etc.. ;)

So, I tried to follow the link to the sketch but it looks like the link is broken.

you said I²C is slow. is ISP or RX-TX faster?

i get a height incorrect error when flashing

Though not of me, the most asked questions I hear are "Hey, you come here often?" followed by "What's your sign?" ... I gotta find a better place to hang out ;) sorry;)

GPS Link is broke, can you update the link or tell us what the module details are pls.?

So on 4s many magics will happen i guess

hello thank you for making this vid. i,m geeting a error when i try to upload the skecht i dont know what to do , i am a noob when it comes to programing Arduino: 1.6.9 (Windows 7), Board: "Arduino Nano, ATmega328" GPS_MaxSpeedDisplay:20: error: #error ("Height incorrect, please fix Adafruit_SSD1306.h!"); #error("Height incorrect, please fix Adafruit_SSD1306.h!");

is it possibe to use a other gps ? regards

You should structure your code as OOP Object Oriented Programming and move away from procedural coding. Because that a very large code to refresh procedurally. In the time that you refresh the screen the GPS had sent 50 times the information. That's the reason why you get a multiple/division of 10. It gets every 5 sec in sinchrony and the rest of it will not match, because everything under 5 seconds is not a multiple of then.

anyways whats that in mph? as kmh is crap measurement i need mph lol?

Flying FPV?

i understand i will order a new gps. thanks

Hello, i am building your speed logger, but in my case for skiing. I have a problem were I think you might can help me. I have bought this GPS module drotek.com/shop/en/drotek-parts/613-ublox-neo-m8n-gps-hmc5983-compass-xl.html but it doesn't want to work. I changed it to 10Hz. do you know were the problem is or how i can get it to work ? Thanks and sorry for my bad english.

kilometers not killer meters!

hello @iforce2d . i want to build this speed logger and shall buy Arduino promini, gps neo 7m, and lcd oled 128x63. but your link for wiring and the code is broken. could you provide me the wiring and code please ?
