Detailed Description

QXK/C port example for a generic C compiler.

Definition in file qxk_port.h.

Macro Definition Documentation

◆ QXK_ISR_CONTEXT_

#define QXK_ISR_CONTEXT_ ( ) (getSR() != (uint32_t)0)

determination if the code executes in the ISR context (used internally in QXK only)

Definition at line 48 of file qxk_port.h.

◆ QXK_ON_CONTEXT_SW

#define QXK_ON_CONTEXT_SW 1

activate the context-switch callback

Definition at line 51 of file qxk_port.h.

◆ QXK_CONTEXT_SWITCH_

#define QXK_CONTEXT_SWITCH_ ( ) (trigSWI())

trigger context switch (used internally in QXK only)

Definition at line 54 of file qxk_port.h.

◆ QXK_ISR_ENTRY

#define QXK_ISR_ENTRY ( )

Value:

do { \
    QF_INT_DISABLE(); \
    ++QXK_intNest_; \
    QF_QS_ISR_ENTRY(QXK_intNest_, QXK_currPrio_); \
    QF_INT_ENABLE(); \
} while (0)

Define the ISR entry sequence, if the compiler supports writing interrupts in C.

Note: This is just an example of QXK_ISR_ENTRY. You need to define the macro appropriately for the CPU/compiler you're using. Also, some QXK ports will not define this macro, but instead will provide ISR skeleton code in assembly.

Definition at line 66 of file qxk_port.h.

◆ QXK_ISR_EXIT

#define QXK_ISR_EXIT ( )

Value:

do { \
    QF_INT_DISABLE(); \
    --QXK_intNest_; \
    if (QXK_intNest_ == (uint_fast8_t)0) { \
        QXK_sched_(); \
    } \
    QF_INT_ENABLE(); \
} while (0)

Define the ISR exit sequence, if the compiler supports writing interrupts in C.

Note: This is just an example of QXK_ISR_EXIT. You need to define the macro appropriately for the CPU/compiler you're using. Also, some QXK ports will not define this macro, but instead will provide ISR skeleton in assembly.
