Hi Michael,

thanks again for your help.

Here is the Timer part of the VirtualWire.h library. I’m not very comfortable with this part of the code but I guess that it uses Timer1.

I’ve download the VirtualWire Library v1.9 just here http://www.open.com.au/mikem/arduino/

// Speed is in bits per sec RF rate

void vw_setup(uint16_t speed)

{

// Calculate the OCR1A overflow count based on the required bit speed

// and CPU clock rate

uint16_t ocr1a = (F_CPU / 8UL) / speed;



#ifndef TEST

// Set up timer1 for a tick every 62.50 microseconds

// for 2000 bits per sec

TCCR1A = 0;

TCCR1B = _BV(WGM12) | _BV(CS10);

// Caution: special procedures for setting 16 bit regs

OCR1A = ocr1a;

// Enable interrupt

#ifdef TIMSK1

// atmega168

TIMSK1 |= _BV(OCIE1A);

#else

// others

TIMSK |= _BV(OCIE1A);

#endif



#endif



// Set up digital IO pins

pinMode(vw_tx_pin, OUTPUT); // currently configured to IO pin 12

pinMode(vw_rx_pin, INPUT);// currently configured to IO 11

pinMode(vw_ptt_pin, OUTPUT);// currently configured to IO 10

digitalWrite(vw_ptt_pin, vw_ptt_inverted);// currently configured to IO 0

}

Sure you will understand this better than me ::)

Hi Michael,

I’ve troubles with the use of and simultaneously and I think it’s due to the Timer part but I don’t know how I can fix this.

the receiver is not receiving data if I setup “DigitShield.begin();” which is needed to drive the led segments.
The receiver works and I can watch my data on the Serial if I bypass it “//DigitShield.begin();”
Of course, the DigitShield library works great if I use it without VirtualWire.

#include 

#include 



int i;

int val;



void setup(){

Serial.begin(9600);

vw_setup(9600);

vw_rx_start();

DigitShield.begin();

Serial.println("Ready");

}



void loop(){

uint8_t buf[VW_MAX_MESSAGE_LEN];

uint8_t buflen = VW_MAX_MESSAGE_LEN;

if (vw_get_message(buf, &buflen)) { // check to see if anything has been received

for (i = 0; i < buflen; i++) {

val = buf;

Serial.print("temp :");

Serial.println(val);

DigitShield.setValue(val);

}

}

}

Hope you will have suggestions.
Regards
Vince
