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() != 0U)

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

determination if the code executes in the ISR context

Note: This is just an example of QXK_ISR_CONTEXT_ (for ARM Cortex-M). You need to define the macro appropriately for the CPU/compiler you're using. Also, some QK ports will not define this macro, but instead might test the interrupt nesting up-down counter (QXK_intNest_).

Definition at line 55 of file qxk_port.h.

◆ QXK_ON_CONTEXT_SW

#define QXK_ON_CONTEXT_SW 1

activate the context-switch callback

Definition at line 58 of file qxk_port.h.

◆ QXK_CONTEXT_SWITCH_

#define QXK_CONTEXT_SWITCH_ ( ) (trigSWI())

trigger context switch (used internally in QXK only)

Definition at line 61 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 (false)

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 73 of file qxk_port.h.

◆ QXK_ISR_EXIT

#define QXK_ISR_EXIT ( )

Value:

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

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.
