// Set the digital IO pin to be for transmit data // Defaults to 12 extern void vw_set_tx_pin(uint8_t pin); // Set the digital IO pin to be for receive data // Defaults to 11 extern void vw_set_rx_pin(uint8_t pin); // Set the digital IO pin to enable the transmitter (press to talk) // Defaults to 10 extern void vw_set_ptt_pin(uint8_t pin);
so you may not need that for your device.
// Initialise the Wireless Receiver IO and ISR // set Virtual Wire data input to Pin 9 from 11 vw_set_rx_pin(9); // found this in forum 25 Aug 09 // set the Bits per sec vw_setup(2000); // Start the receive PLL running vw_rx_start();
// Initialise the IO and ISR for VirtualWire vw_setup(4000); // Bits per sec - had to double from 2000 with 8MHz 3.3V Pro-Mini
with D10 being used as a Column pin for a keypad, and D11/D13 not used.
with SPI to a MAX7221,
functions like digital write,analog write etc can too be done there
