RF code help

[Wizpic]

Has anybody got some code samples in Picbasic pro or Proton code for a 2 button transmitter
stright on/off or working code that i could have. If you do not want to share on here PM me and we can talk that way.
I NEED you help i don't inder stand aasm/c code I've searched and shearched but no luck
 
Thanks

Better use PT2262 for Transmitter and PT2272. Its easy and you dont nead  microcontroller.

[Wizpic]

Thanks but i have got it all sorted and working now using a pic chip

Hi Wizpic
 what kind of transmitter do you use?

  is a  pic  also used for the receiver?

[Wizpic]

I use a 16F684 smt as transmitter (433mhz) and a 16F628A as receiver and test prove (just using wire as an aireal) 100mtrs plus I have got the correct Aerials on order so i should be able o get further hopefully.

hi
 you have tried to  negate one of them ? if this cannot the transmitter be defined high as 1 with the receiver one yet for a  long time.

Not sure what you mean could you explain a bit more
 
 my transmitter only transmits for 1.5 seconds then stops until button is pressed again, It can work upto 8 channels (only one at a time).
I am in the process of rewriting software to use the same chip for TX/RX with Momentary Outputs ,Latching Outputs. the tx unit only works when button is pressed

it is fully working with no problems

oops, I have misunderstood ...

 do I  understand correctly?

  transmitter button  1 pressed >> tx >> receiver toggle output 1 (or high or low)

  transmitter button  2 pressed >> tx >> receiver toggle output 2  (or high or low)

  and so on

here's my code, works gr8, did it for Robotic Control. See if it helps
 
written in PBP 246.

hi charlie,

iam also looking for RF code (16f877a  to 628a) plz share it.iam using ST-TX01 -ASK TRANSMITTER MODULE.

Thanking you.

best Regards.

Sorry for NO CODE,

here is my code.

Just toggle function using PIC and PBP

Winpiz,

If possible, could you share the schematic please. Thanks.

HI CHARUDAT,

THANK YOU VERY MUCH FOR THE CODE,I TRIED YOUR CODE BUT ITS WORKING BUT NOT PROPELY..IT  WORKS ON MULTIPLE PRESSES..COULD YOU PLEASE CONVERT THIS CODE INTO MANCHESTER..

THANKS...

BEST REGARDS

If possible, could you share the schematic please. Thanks.

I will have to dig it out has i have not played with it for a long time give me a bit of time and i will have a look for it

but it's really simple a 5V regualtor,PIC (16f628), 2-8 buttons on portb(held low with resistors and going high when button is pressed) then a 433mhz TX unit, using porta.2 as tx and port.3 for led

the rx uint with RX signal coming in on port.2 and the relays go on portb which the realys are fed via transistors

hope that helps I will dig them out and get it finished i would like to start and play with them again

HI, maybe this help you.

have a good example serial data on RF TX an RX and use librarys on PBP is more simple
