Talex lite - Using the PocketGPSWorld database

Haha, thanks Smile

When I first read it I got the dreaded feeling of having wasted many hours of my life! Purging the whole mobile database would be suicide Laughing

But with news of flying penguins, anything might happen!

Now that's out of the way, a quick update on my progress Smile

I started writing the software last night to convert the PGPSW style of data into talex style data (read my post earlier about virtual 'driving' down roads to get the extra points at junctions needed etc.). So far I've got an alogirthm pinpointing which road the camera is actually on. No mean feat, as the map data is just millions (literally) of GPS coords with a bit of extra data saying how they are joined. I had to whip out some linear algebra (think cross products) that I thought I'd never actually use in real life... just did a term of nasty maths at univeristy - it's nice to actually find a use for it! Anyway, now I know the road I'm on, it's not so hard to move along it and generate the points I need for the talex.

Finally, another call for some old novus updates: I currently have version 7113, 8033, 8034 and 8035. If anyone has any other versions, please upload them to rapidshare and give me the link so I can take a peek. It would be really useful Smile

p.s. novus have messed up their update yet again, just tried the delta update and it wipes the lite clean as if it was a rider update Rolling Eyes

Dilemma

I don't want to subscribe to Talex anymore once it's expired and Novus are allegedly producing dodgy downloads.

I'll use allegedly because I have heard from someone over at BriSkoda who has received a threatening letter from Novus re adverse forum publicity - allegedly.

the lesson is always keep the previous update and don't delete it like I did until you've tried out the latest update... (I always try the talex ones first) I just copied the previous from my backup drive to get it back working though, so it's not the end of the world. But it's embarrassing for novus to mess up twice, particularly for owners who haven't followed the threads and don't know how to get it working again.

Could one of the admins describe the behaviour of the camera ID for me please?

Is the camera ID unique? i.e. once a camera has been added to the database and deleted, no future camera will ever take up that ID again?

I'm asking because I'm working out how to deal with the addition/deletion of cameras from the PGPSW database and delete/add to my talex database.

I plan on finishing off the point generation program tonight... if all goes to plan I can get it converting... worryingly it isn't too efficient atm (rough calculation says it'll take about 50 hours to complete) so I'll either optimize or leave it running for a few days Razz

Thanks

the ID is unique throughout the entire worldwide database. i.e. there is not gatso:1, redlight:1, mobile:1, nor is there a uk gatso:1 and a euro gatso:1

if a camera is removed then that id may be used again BUT only for the same camera if it returns. i.e. if a gatso gets beheaded and we remove it from database (in reality nothing gets removed, we just change it's status so you don't get it in the download) and a few weeks later it gets repaired then it would keep the same number.

if a new camera was built a bit further down the road then the replacement would have a new camera id

hope that helps

Thanks for your help MaFt.

I think my program is now accurate enough to start generating... with a bit of optimisation that should take about 30 hours ( Shocked

)

Here's a few points I've generated plotted on google maps.

They're the red dots (you'll need to zoom out to see them and zoom in on them for detail). Click on them for info and refer back to my posted images a few pages back to see why they're placed where they are Smile

Now I need to write the program to convert these generated points into a binary file suitable for upload to the talex... shouldn't take long as I know exactly how the data needs to be formatted now Smile

i ve got a similar unit branded indic8tor and just out of curiosity flashed it with the novus software, a brief test shows it is working displaying time, speed etc.
It now has no voices only bleep warnings, but this may be normal?
pressing the left button also plays some voice extremely slowly, guessing this is a user camera add confirmation.
i`d be grateful for a link or summary of the novus manual to get an idea of what it is supposed to be doing, can`t find one anywhere

Currently looking through the manual posted (i think skoda forums) for the winbond sound chip maybe i can fix some sound stuff myself.

Happy to test anything that comes up, including that linux implementation that has been mentioned, quite happy to run rockbox on my 3g ipod so dont see why not on this too.

thx talexuser

the place you pointed me to kinda helped, confirmed what was on screen.

just to report my findings for anyone else with talex clone hardware, it seems that you can run the novus update, and the software seems to operate fine, but if your unit isnt a actual talex or novus, then it's possible you will not have any voice warnings at all.

i'm guessing this is due to the voices being kept seperate from the main program memory, on a differnet chip i believe.

looking at the manual for the suspected chip (thx to cheezemonkhai ?) guess the only way to proceed is either chip out, or possibly write a custom firmware that will write to the chip for me... either way is beyond my current capability.

it is fun to tinker, and has been interesting to see the other software on there, and would really like to use the pocketgps cam DB, but the original firmware is now back on until i learn more.
