transceiver 433 MHz

[jonas2]

Hello

I want a sample program in pbp, I want to send
15 bytes by the bias of an RF module 433 MHz and receive
On another module.

thank you

[mackrackit]

Have you searched the forum for examples? There a plenty out there.
Can you send and receive the data with wires?

Hello

I will test this way?

touche VAR BYTE
name0 var byte
name1 var byte
name2 var byte
name3 var byte
i var byte
ID Var Byte


envoi:
SEROUT2 PORTA.3,T9600,["SYN",ID,name0,name1,name2,name3]
GOTO debut



reception:
Serin2 PORTA.3,T9600,[wait("#SYN"),ID,name0,name1,name2,name3]
GOTO debut

Maybe without the "#" symbol on he SERIN command.

Hello
Thank you for your help, do you have a sample program.
I want to transmit and receive 24 bytes.
thank you

[Ioannis]

If your data are always 24, then use an array, load the date at the array elements and then send the array.

I 'd use Hserout if my controller has hardware USART.

Hserout [STR array\24]

or

SerOut2 port,mode,[STR array\24]

Hello

Thank you for your help, what do you think of this program?

Compteur Var Byte '
TX_Donnee Var Byte[24] ' Donnee emission
RC_ID Var Byte ' emission IDentificateur
RX_Donnee Var Byte[24] ' Donnee reception


Loop: ' emission

For Compteur = 0 to 23 ' donnee
TX_Donnee = Compteur ' Transfert de Compteur vers TX_Donnee
Serout2 PortA.0,B2400,["#OK",RC_ID,TX_Donnee] ' envoie l'ID suivie des donnnees

Pause 100 '
Next
Goto Loop



Loop1: ' reception


Serin2 PortA.1,B4800,[wait ("#OK"),RC_ID,RX_Donnee] ' attend reception l'ID
if ID=32 THEN




Goto Loop1 ' boucle

Sorry but no!

You lack basic knowledge of the lanquage syntax.

I am sorry to say that, but you must read the PBP manual and test the commands before doing this.

Just to help you going, arrays are accessed by their element position, e.g. TX_Donnee = Compteur is wrong and should be TX_Donnee[Compteur] = Compteur.

You might want to verify your send/receive data rates as well.

Hello

Thank you for your help, I'll try this way?


j var byte
datac Var Byte '
TX_Donnee Var Byte[24] ' Donnee emission
ID Var Byte ' emission IDentificateur
RX_Donnee Var Byte[24] ' Donnee reception



Loop: ' emission

ID=32 ' l'ID

For J = 0 to 23 '
TX_Donnee[J] = datac ' Transfert de datac vers TX_Donnee

Serout2 PortA.0,B2400,["#OK",ID,TX_Donnee] ' envoie l'ID suivie des donnees
Pause 100 '
Next J
Goto Loop



Loop1: ' reception


Serin2 PortA.1,B4800,[wait ("#OK"),ID,RX_Donnee] ' attend reception l'ID suivie des donnees

if ID=32 THEN

For j = 0 to 23 '
datac[J] = RX_Donnee ' Transfert de datac vers TX_Donnee
next j

Goto Loop1 ' boucle

[Ioannis]

No, you receive loop is wrong in the logic.

Try this for the receive part:

j=0

While j<24' reception
  
    Serin2 PortA.1,B4800,[wait ("#OK"),ID,RX_Donnee] ' attend reception l'ID suivie des donnees
	
    if ID=32 THEN
        datac[J] = RX_Donnee           ' Transfert de datac vers TX_Donnee
        j=j+1
     endif
Wend					                        ' boucle
