433 Mhz Data Receiver

[Pesticida]

Ok,I read now the data from the PIC16F84 eprom.
When I push the button 1 and save the data trough the receiver to the PIC I can see on the adress 0000: 01 00 03 EF 36 00 00 00 when I push the button 2 I can read on adress 0000:01 00 03 ED 2E 00 00 00.
I think this is the right code!

Hi,
I have another question how can I check this number "108219" on Porta.0 with serin command.
Example serin porta.0,N300,[108], B0 this is for number "108",but i want to check the complete number how can i do this,I become all the time number owerflow while this is to big !
Thanks a lot people for help.

Thanks people for so much help.
I will never forget this!

Would you mind posting a snipet of your Serin code. I too am using a 433Mhz receiver which has 4 outputs. 1-3 are depending on which of the 3 buttons on the fob are pressed, but the 4th emits serial data, like the serial number of the fob device.

I owuld be interested in how you are capturing your serial code.

Many thanks,

Steve

Hi,
I try to capture with audio visual method or connect direct from transmitter output to my second PIC.
But the problem is I can not make the same wave I dont know why!, I have tryed with 300 Baud then with 1200 but I can not have the same binary tone.
I use just a normal Serin command:

Define LOADER_USED 1


Include "modedefs.bas" ' Mode definitions for Serout



ADCON1=7
define osc 4

DEFINE HSER_RCSTA 90h
DEFINE HSER_TXSTA 24h
DEFINE HSER_SPBRG 207 ' 1200 Bauds
DEFINE HSER_CLOERR 1









' Alias definition
' ================
'
'
RCIF VAR PIR1.5 ' Receive interrupt flag (1=full , 0=empty)
TXIF VAR PIR1.4 ' Transmit interrupt flag (1=empty, 0=full)

' Variable definition
' ===================


B0 var byte

pause 10 ' safe start-up delay


Main:

serin porta.0,N1200,B0
serout porta.1,N1200,[B0]
hserout [#B0]
goto main

This photo is what I have captured from my transmitter.
This wave is made from the transmitter 5 times.
I have found on the web how can I read this audio data but I dont know any more where is this homepage ! :-)

Hi People,
i have a question ,can I use this manchester code like in this example.
Trough PortA.0 is incoming encoded data from my transmitter and is then decoded and trough PortA.1 is going encoded data out.

Define LOADER_USED 1
Include "modedefs.bas" ' Mode definitions for Serout

ADCON1=7
define osc 4

DEFINE HSER_RCSTA 90h
DEFINE HSER_TXSTA 24h
DEFINE HSER_SPBRG 207 ' 1200 Bauds
DEFINE HSER_CLOERR 1

n var byte
d var byte
myVar VAR byte
CounterA var Byte
ErrorFlag var Bit
MyData var Byte
encoded var Word
v var word

pause 10 ' safe start-up delay

Main:

serin porta.0,N1200,v

ErrorFlag=0
For CounterA=0 to 7
If v.1=0 then
MyData.7=0
If v.0=0 then ErrorFlag=1
else
MyData.7=1
If v.0=1 then ErrorFlag=1
endif
v=v>>2
If CounterA<7 then MyData=MyData>1
next
goto encodemanchester
encodeManchester:
For d=0 TO 7
IF mydata.0[d]=0 Then
encoded.0[d*2]=0
encoded.0[d*2+1]=1
Else
encoded.0[d*2]=1
encoded.0[d*2+1]=0
EndIF

serout porta.1,N1200,[encoded]
hserout [encoded]

Next

goto main
end


Please for help,thanks very much.
