Hello! Maybe I just don't know something, but I made convenient macros which turns this code: [code] ... // For request DDRA &= ~_BV(PA2); // For LED DDRB |= _BV(PB3);
// Wait for request loop_until_bit_is_set(PINA, PA2); // Turn LED on PORTB |= _BV(PB3); ... [/code] into this completely equivalent code: [code] ... #define LED_PORT B #define LED_PIN 3 #define REQ_PORT A #define REQ_PIN 2 ... CONF_IN(REQ); CONF_OUT(LED); WAIT_1(REQ); SET_1(LED); ... [/code] Note that in the first code it's easy to make a mistake and remember what port/pin is for. The second code is self-explaining + no mentioned mistakes can ever be made! Someone need this or it's just me who made bicycle? _______________________________________________ AVR-libc-dev mailing list AVR-libc-dev@nongnu.org https://lists.nongnu.org/mailman/listinfo/avr-libc-dev
