My small hardware to RR

mauri · 02-26-2005, 05:33 AM

Ok, one photo of my definitive hardware to use with RR:
oevery 57 minutes for once of 3 minutes, so the data don't lose him memorized in the RAM memory of the GPS, it resolves the problem that immediately starting the PC the infos is had on the position) and the reader of temperature with for DS18B20 instead of the kit to be purchased, perfectly compatible with RR, everything built home made.
To the voltmeter i use one P12F675 , and to reader of temp. use one P12C509A ,two uP by Microchip.
When Guino implements the voltmeter with RR and I will have made a will embedded,i publish the material (it already works however it needs to make the sw in VB to integrate with RR, Guino it already knows this thing) the reader of temperature and already everything ok.

EDIT:if someone wants to make the sw to the place of Guino in VB, to decrease you job (i am not a coder of VB but an "electronic man"

) you contact me in PM, then we pass everything to Guino

Very good!
I'm very interested in the voltmeter (seperated from temp.), temperature I got by MBM...
But sorry, I can't help you with coding too

I'll work on the voltimeter support this weekend...

You hare The best!!

Thanks Guino

Tested all, and finish post all packet project to make home made

In enclose a new file .txt saved with Yperterminal for my volmeter hardware as you have asked me.

The data / coefficient and:

600 = 11,78Volt

11,78 : 600 = 0,0196363 (number of coefficient)

Com port settings:
2400baud No parity ,8bit ,1stop bit

Thanks

Ok, I've added support for the voltimiter.. just add the followind line to your RR.INI:

vcomport=<COMPORTNUMBER>

if you use RRConfig afterwards, it will erase the line (since there's no support for it yet). Once you've added that, you should edit a skin and add a LABEL with the code "VOLT1" and it should display the corrected voltage. If you by any chance can modify your board to measure multiple batteries, you can output the data in the same format just simply change V1 to V2 etc.. I've built support for up to 4 (Four) voltage readings. I know for a fact many people have more than one battery, so it would be very helpful for those if it is possible to do it.

will the hardware be something we can make or do we have to buy it?

guino · 02-27-2005, 10:53 PM

Mauri is going to make everything available to make at home, but I assume you'll need some knowledge of eletronics to buid it... I for one wouldn't mind ordering a pre-built one if Mauri agreed on making/selling them..

RoyN · 02-27-2005, 11:16 PM

OK, not sure what exactly it is... I kind of picked up it keeps GPS position for a quicker lock, and then what does the voltmeter/thermometer come in???

TimmyM · 02-27-2005, 11:20 PM

I'm confused. What does it do?

guino · 02-27-2005, 11:25 PM

Haha... there are two projects in this thread.. Anyway, one is a Temperature sensor for up to 4 Sensors -- I have 2 sensors installed to measure temperature inside and outside the car (I could definitely use the two other to measure engine and exhaust temperature -- if I wanted to). This first project is available for ordering around the world.

The second project is a voltimeter to measure the power level of your Battery. This project was developed by Mauri, and he is going to post information on building the unit for whoever wants to.

hmmm ok! got it now!

this is what threw me off

Tonight tested my voltmeter.
EDIT: the second function to my hardware its to resolved the problem by GPS receiver.
Every receiver GPS with incorporated spar has tor inside particularar component called " condenser Supercap " that has the function to also feed the small memory RAM to inside when the principal feeding and absent, practically ago from backup battery instead of using a mini standard battery.
This because the last data received by the GPS are memorized in the RAM memory, so to the reboot the GPS has suffered the data to work without making a new search of the satellites, that usually employs around 40 seconds.
After 5 hours around the supercap he unloads, the GPS loses the data in memory, and so it employs to the reboot the 40 seconds.
With my hardware this doesn't happen, every 57 minutes power the GPS for the time of 3 minutes, extinguishes then, in continuous loop, thin to that it doesn't ignite the GPS with the 5 Volts.
In this way the Supercap is reloaded every 57 minutes,in this time, (3 minutes), it is reloaded, and is ready are had in memory the data received by the GPS.
I hope that someone has understood....

However this and an optional, if don't want this function, the voltmeter works equally...

Tests with RR I will publish the material with "README.txt" to make.

Ok Guino, tested my Voltmeter with RR and work correctly

Use for test simple the main menu skin by brushmetal.
See the screenshot.
The range if read the volt perfect is 8,5 to 15,5V (to car use is ok,this was my idea to i begin of my project).
Tested in my laboratoryand PC home, but in the car is the same i think.
This weekend if i make time put on my car for test, then i see if all ok

when all and perfect, I put in download mine plans.

EDIT: my reader of temperatures and already all ok ( is the same of kit , but you have make home made)

The DS18B20 sensor work in the range of temperatures from -55°C to
+125°C (-67°F to +257°F)
0.5C accuracy from -10°C to +85°C
For measures in water or liquids to always ISOLATE, remember

THANKS Guino for you good work

This sounds like a very interesting project to undertake. How hard would it be to adapt one of the temps to my engines temp sending unit? How about oil pressure? I don't have ODBII so this would be something I would be interested in.
