ARM, RISC-V контроллеры

Лучше через inline функции*  #define RS485_ENABLE_PORT PORTE #define RS485_ENABLE_PIN 1 #define RS485_ENABLE_CTRL PIN1CTRL #define RS485_DIRECTION_PORT PORTE #define RS485_DIRECTION_PIN 0 #define RS485_DIRECTION_CTRL PIN0CTRL INLINE static void Rs485_232_Enable() { RS485_ENABLE_PORT.RS485_ENABLE_CTRL=PORT_OPC_TOTEM_gc; RS485_ENABLE_PORT.DIRSET=1<<RS485_ENABLE_PIN; RS485_ENABLE_PORT.OUTCLR=1<<RS485_ENABLE_PIN; } INLINE static void Rs485_Disable() { RS485_ENABLE_PORT.RS485_ENABLE_CTRL=PORT_OPC_TOTEM_gc; RS485_ENABLE_PORT.DIRSET=1<<RS485_ENABLE_PIN; RS485_ENABLE_PORT.OUTSET=1<<RS485_ENABLE_PIN; } INLINE static void Rs485_EnableTx() { RS485_DIRECTION_PORT.RS485_DIRECTION_CTRL=PORT_OPC_TOTEM_gc; RS485_DIRECTION_PORT.DIRSET=1<<RS485_DIRECTION_PIN; RS485_DIRECTION_PORT.OUTSET=1<<RS485_DIRECTION_PIN; } INLINE static void Rs485_DisableTx() { RS485_DIRECTION_PORT.RS485_DIRECTION_CTRL=PORT_OPC_TOTEM_gc; RS485_DIRECTION_PORT.DIRSET=1<<RS485_DIRECTION_PIN; RS485_DIRECTION_PORT.OUTCLR=1<<RS485_DIRECTION_PIN; } Или с помощью шаблонов (если МК позволяет конечно).
