Not using macros regularly the xmega io system is forcing my hand a little. I've made my own new macro in an attempt to make testing I/O pins easy but have come stuck with a macro not accepting a #define as its arguements, as shown. Any clues TIA.?
// PORT / PIN DEFINITIONS
// Use following standard macro to turn output on
//
// PORT_SetOutputBit( _port, _bitPosition )
// Use following standard macro to turn output off
//
// PORT_ClearOutputBit( _port, _bitPosition )
// This is MY NEW MACRO to get the port data
#define PORT_GetPortBit( _port, _bitPosition ) ( (_port)->IN & (1 << _bitPosition) )
// These are the port defines - note there is one differnt
// I'd like to define a name as a port AND port pin position in one go - if possible
#define bluetooth_power ( &PORTB, 0 ) // 0 = Power On
#define sensor_power ( &PORTB, 1 ) // 0 = Power On
#define red_led ( &PORTF, 6 ) // 1 = Led On
#define green_led ( &PORTF, 6 ) // 1 = Led On
#define link_established_bp 1
//This is how it works - and this compiles ok
if (PORT_GetPortBit( &PORTC, link_established_bp ) == 0) {}
//This is how I WANT to use it- bit this fails
//complaining the macro only gets one argument
if (PORT_GetPortBit( sensor_power) == 0) {}
