Wow...
After, well.. getting it.. it all makes sense! Go figure right? :D I was right though, I was over thinking it.

Well understanding it more, anyways:D
But you're right, removing the const and trying to have a variable that I can send just doesn't work! I'm able to send small messages that I've preset on the transmitter, which is kind of what I wanted to do in the first place.

But I seen over on Practicalarduino.com they used VirtualWire to send over information from a Lacrosse Weather Station(on their roof) to the receiver every 2 minutes. Just.. so..sexy! I'm loving learning new things everyday.

Thanks again for all your help! Understanding for me.. well, takes time, sometimes! :D That's what I get for diving in head-first.

But I did try to use the HyperCom library, it doesn't include the LED.h file with it for the examples, which wasn't too bad to work around, but after a little editing, I wasn't able to get a connection. So I'll just work with what I've got for now, it seems to work for other people fairly well, so it's user error. :D I've gotten some sent, now time to work in my LCD, and hopefully be able to send commands via Serial on the transmitter.

Only time will tell! Thanks again for all your help!!

Hi everybody,

I'm trying to get the grove 433Mhz work on my arduino uno without success for 2 weeks now..
My projet is to use attiny85 chips to receive a command from the rf link to make a led blink.
I've try to use manchester on it (see https://github.com/mchr3k/arduino-libs-manchester for more details).

So i have connected the rx and tx on my arduino just for the test, and i receive nothing!
Do you think it's possible to get it work on the same board to be sure it can work?

Does someone even build something with an attiny85?

This is the code for testing on arduino uno:
#include <MANCHESTER.h>

#define TxPin 2 //the digital pin to use to transmit data

#define RxPin 12

unsigned int Tdata = 0; //the 16 bits to send

void setup()
{
MANCHESTER.SetTxPin(TxPin); // sets the digital pin as output default 4

MANCHESTER.SetRxPin(RxPin); //user sets rx pin default 4
MANCHESTER.SetTimeOut(1000); //user sets timeout default blocks
Serial.begin(9600); // Debugging only

}//end of setup

void loop()
{
Tdata +=1;
MANCHESTER.Transmit(Tdata);

unsigned int data = MANCHESTER.Receive();
Serial.println(data);

delay(100);
}//end of loop

Thanks!!
