Hello,

Ok I'm coming now to the conclusion that the G sensor is not the really thing for measure if a Elevator is moving and how fast is moving ! :-)

Maybe have some one another better...

Ok,

Now when I correct understand I must the first Acceleration Change to measure How long the Acceleration is during then I know the distance for that Time for ex. 1 Seconds.
And I can now...

Skimask what bandwith should I use ,between 1Hz to 2Khz ?

I use this for the moment:

Main:

ADCIN 0, adval[0]
Pause 1
ADCIN 1, adval[1]
pause 1

HI :-)

Thanks People,

Skimask the Car don't change the Speed.

Thats mean that a Elevator for a little bit is accelerating and then have a costant Speed for a time T.
When is slowing down...

Hi Skimask,

The Mnimum Value I have is 130 and the Max Value is 167 .
= 3,173 Volt - 2,5 V = 0,673 V ~ +-2g

What You mean what is the Best way to found the Speed and the ~ Distance?

Thanks...

Hello,

I make a Accelerometer Sensor Circuit for a Elevator,and I'm using a ADXL311J with a Rail to Rail OP Amp (AD6809) and 5 Volt Ref,50 Hz Bandwith with 0.1uF.
When I read now the Data on The...

Hi

I found the mistake,I use after HSEROUT just 10 mS Pause this is to cheap,I'm using now 50 mS and all is oK!

The receiver part need ~20 mS to be Ready,My problem is that i dont use the Busy...

Hi

I have a Problem with my ER900TRS Easy Radio Transceiver!

When I use this Syntax: hserout ["A",DEC3 Adval[0],"B",DEC3 Adval[1],13,10]

I Receive on my PC Corrupt data,why?!

But when I...

Hi Skimask,

No I'm not looking for Slow Voltage drop,I need a Secure Alarm Device,this was just a coincidence that I found this Error.

I can use the Device in two Mode :

Mode1 = On/Off to...

I forgott to say that this Problem is happen just when the voltage is slow decreasing!
I think that I should use a Schmidt Trigger between Input and pcf8574A.

Hi,

I have Building a 24 Inputs Alarm Device,all is working fine,but :-) i have just a little Problem
when I have a Voltage on one Pin between the HI and LO PDF Specification the INT is still...

hi

I found it! the problem was somewhere else .

All is ok with my word Variables :-)

Thank you all for help!

regards Pesti

Ok


Thanks Jumper,can I word arrays just increase like this:

ML_Second var Word[24]
ML_Alarm var bit [24]
ML_End_Time var Word [24]

for S = 0 to 23

Jeeeze....Can not Help me ;-)

Ok sorry! :-)

I make a mistake i understand the lvdin is the tigger Low Voltage level.

Regards Pesti

Hi

When I use The External LVDIN Input how I can set the Low Voltage Detection Limit while I must to set the LVDCON ,LVDL3:LVDL0 all to 1.

Thank you for any Info

Regards pesti

Hi Skimask

thanks

Ok but what is when the value for ML_Seconds.lowbyte[N] is grater then 255 I must to compare the highbyte too!?

How is that are the two bytes in a word connected,i mean...

hi

Ok I try but I have a Problem!

I have this :
ML_Seconds Var Word [24]
ML_Verz Var Word [24]

Here is wrong too!

Thank you very much for the answer.

Now I understand!

You are the best!

regards Pesti

Hi
I have a Variable Problem!

I have a Variable DataIn:

Datain VAR Byte [3]
Dummy VAR Byte [3]

now for example i want to use this to compare the bits and to found what bit have change:

How much Photos!

Sorry but I dont understand what you mean with average! :-)

1-2 Months.

I need this for a Elevator,I have in the Elevator a Security system that is connectd with a GPRS Modem.
When someone Push the SOS Button then I make a single Picture shot and...

Hi,



Something between 10-40 Seconds Sending and ~ 80 KB.

For the moment I want to use this Resolution 640X480 Pixel.

Regards Pesti

Hi,

My Idea is to capture frome some Digital Kamera a Picture and than to Read with the Microcontroller and to send via Gprs Modem.

Thanks
