Thanks Jason.

I still have much work to do (by Jordi Gauchia)

I continue working on my little project.

Now I've parsed OziExplorer WPT file format.

I use it to navigate between waypoints (distance, bearing, heading...) .

This is a picture showing a map drawn with 481 waypoints



It would be nice that people share their projects in NavSpark community

Well, while I try to use the compass, I put a video of my project showing a BMP image.
I need to optimize speed, the problem, how?... any ideas?

How many bytes you need to move to fill screen? Don't know if free SD Card FAT32 library is optimized for speed. Maybe you can try reading BMP file alone to see how long it takes, or writing same pattern to fill screen to see how long it takes, to understand where bottleneck is. Easiest way might be to lower resolution without moving so much data... (by Jason Lin)

Hi
Image is 320x240
I use fill pattern to clear screen or change background color and there are no more difference in time.

Maybe the problem is the bmp routine because drawing in screen is fast.
Now I'm not at home... Later I'll upload a video showing some drawing routines that I use to draw map in screen reading points from SD (by Jordi Gauchia)

When I arrive at home I'll test reading files from SD and bmp routines... Maybe optimizing it... I don't know.... Really this "problem" is not very important..... But increase speed will be good!!! (by Jordi Gauchia)

Hi!

With the fantastic help of the user Ralph Loveday , finally my HMC5883L compass module Works!!!

I've modify my old Arduino (ATmega) code to draw a digital compass in screen, and this is the result (sorry for the video quality )

Now, it's time to do calibration option and solder the module properly in the PCB.

Cheers!!

Hello again!
After a long time I abandoned my project, I returned to work on it.

In the next picture you can see how the position shown in real time (moving well) on a map obtained from OpenStreetmap.



Now, I'm working on the navigation screen and breaking my head to show a directional arrows (left or right) to show me where I have to move.
I guess I'll have to do some kind of calculation between Course and CourseTo ....



Merry Christmas! and enjoy your projects!

Great project!
How are you taking the OSM XML and converting it to an image?
