Quadravox question

Archiver

Hi There,

I am doing a BS2 project involving a quadravox 306m1 sound module. When I
attach it to a speaker it works fine, the 1W Amp does a good job.
But when I connect it to my hifi using a line in it is very very low volume.
Does anyone know why? Is there something I must know about how to connect
it?
What is the AUX on the QV-module? Is it a kind of line-out?

Thanks for your help and have a nice weekend,

Uli

Hmmmmmmm

I am not familiar with the 306 but what I can tell you is that if the unit
has the ability of producing 1 watt at I would assume 4 ohms (P=E2/R) or
about 2 volts, would be more than enough to drive the input stage. Most
pre-amp HiZ inputs (call AUX) operate at about 500mv. There is more here
that needs to be checked. If you can look at it with a scope you should be
able to determine the actual output of the amp. One thing you should check.
Most decent amplifiers today are direct coupled. Be sure there isn't any DC
floating on the output of the 1 watt amp. This could raise havoc with the
first op amp stage of pre-amp. Sometimes even shut it down.

hi, guys
have interesting project that need some help
did some serious programming with a GPS OEM module and a BS2 and the Backpack
LCD display. Works great and now displays the lat & lon on the LCD when the
module has what we call a "good fix" or at least 3 satellites in direct view to
give cvorrect GPRMC data line.

Therefore, I want to add a vocal part to this program in place of the LCD.
Quadravox was nice enough to help with sample words such as GPS, LATITUDE,
LONGITUDE, etc. so I have the constants in place.

What I need to do is take the code in a subroutine marked "A" below and "say"
the variables in the quotes named latA(0), etc in the QV306M4P module instead of
displaying them on the LCD. I have a blank speech chip in the module and have
the programmer so the unit is blank..

This message is sort of directed to Jon Williams, as I know he has been
working with GPS and also the Quadravox modules, but open to all that can help

here is the relevant code:

assume the LCD in on P0 and set at 9600 baud just for clarification of the code

time var byte(6)

latA var byte(4)

latB var byte(2)

lonA var byte(5)

lonB var byte(2)

lat_hemi var byte

lon_hemi var byte

status var byte

LINE2 con 192

line1 con 128

I con 254

CLR con 1

N9600 CON $4054



(some more code to getr the data here)



now here is the output I spoke of above as subroutine "A", called "good_fix"::

good_fix:

Pause 1000

serout 0,9600, [noparse][[/noparse]I,CLR]

Pause 1

serout 0,n9600, [noparse][[/noparse]I, LINE2, latA(0),latA(1),"
",latA(2),latA(3),".",latB(0),latB(1)," ",lat_hemi," GOOD FIXLON
",lonA(0),lonA(1),lonA(3)," ",lonA(4),lonA(5),".",lonB(0),lonB(1)," ",lon_hemi,"
"]

goto get_data



as always I thank each and everyone of you for your kind assistance and
consideration

sincerely,

mike m

Download the QV306 demo code from our web site. It will show you how to
"say" numbers with the QV306 or compatible boards. You'll have to move your
arrays into a single word variable and that is very easy to do.

Here's a link:
