hi,

i have a problem with virtual wire 1.27 on an attiny84.......

i think the transmitter works, but iam not shure.....

but is dont receive something......

this is ma sketch for transmitter:
"
#include <VirtualWire.h>

void setup()
{

vw_set_ptt_inverted(true); // Required for DR3100
vw_set_tx_pin(0);
vw_set_rx_pin(10);
vw_set_ptt_pin(9);
vw_setup(2400);
}

void loop()
{
const char *msg = "hello";

digitalWrite(1, true); // Flash a light to show transmitting
vw_send((uint8_t *)msg, strlen(msg));
vw_wait_tx(); // Wait until the whole message is gone
digitalWrite(1, false);
delay(1000);
}
"

and this is my sketch for receiver:
"
#include <VirtualWire.h>

void setup()
{
Serial.begin(9600); // Debugging only
Serial.println("setup");

vw_set_ptt_inverted(true); // Required for DR3100
vw_set_tx_pin(10);
vw_set_rx_pin(3);
vw_set_ptt_pin(9);
vw_setup(2000);

vw_rx_start(); // Start the receiver PLL running
}

void loop()
{
uint8_t buf[VW_MAX_MESSAGE_LEN];
uint8_t buflen = VW_MAX_MESSAGE_LEN;

if (vw_get_message(buf, &buflen)) // Non-blocking
{
int i;

digitalWrite(12, true); // Flash a light to show received good message
// Message with a good checksum received, dump it.
Serial.print("Got: ");

for (i = 0; i < buflen; i++)
{
Serial.print(buf*, HEX);*

  • Serial.print(" ");*
  • }*
  • Serial.println("");*
  • digitalWrite(12, false);*
  • }*
    }
    "
    can anybody help me ?
    sorry for my english (;
    thank you !
