Otherwise the CMSIS-RTOS implementation is no longer +compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation. + + +<b>Function calls from interrupt service routines</b> + +The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR): + - \ref osSignalSet + - \ref osSemaphoreRelease + - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree + - \ref osMessagePut, \ref osMessageGet + - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree + +Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called +from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector. + +Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time. +If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive. + + +<b>Define and reference object definitions</b> + +With <b>\#define osObjectsExternal</b> objects are defined as external symbols. This allows to create a consistent header file +that is used throughout a project as shown below: + +<i>Header File</i> +\code +#include <cmsis_os.h> // CMSIS RTOS header file + +// Thread definition +extern void thread_sample (void const *argument); // function prototype +osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100); + +// Pool definition +osPoolDef(MyPool, 10, long); +\endcode + + +This header file defines all objects when included in a C/C++ source file. When <b>\#define osObjectsExternal</b> is +present before the header file, the objects are defined as external symbols. A single consistent header file can therefore be +used throughout the whole project. + +<i>Example</i> +\code +#include "osObjects.h" // Definition of the CMSIS-RTOS objects +\endcode + +\code +#define osObjectExternal // Objects will be defined as external symbols +#include "osObjects.h" // Reference to the CMSIS-RTOS objects +\endcode + +*/ + +#ifndef _CMSIS_OS_H +#define _CMSIS_OS_H + +/// \note MUST REMAIN UNCHANGED: \b osCMSIS identifies the CMSIS-RTOS API version. +#define osCMSIS 0x10001 ///< API version (main [31:16] .sub [15:0]) + +/// \note CAN BE CHANGED: \b osCMSIS_KERNEL identifies the underlying RTOS kernel and version number. +#define osCMSIS_RTX ((4<<16)|61) ///< RTOS identification and version (main [31:16] .sub [15:0]) + +/// \note MUST REMAIN UNCHANGED: \b osKernelSystemId shall be consistent in every CMSIS-RTOS. +#define osKernelSystemId "RTX V4.61" ///< RTOS identification string + + +#define CMSIS_OS_RTX + +// The stack space occupied is mainly dependent on the underling C standard library +#if defined(TOOLCHAIN_GCC) || defined(TOOLCHAIN_ARM_STD) +# define WORDS_STACK_SIZE 512 +#elif defined(TOOLCHAIN_ARM_MICRO) +# define WORDS_STACK_SIZE 128 +#endif + +#define DEFAULT_STACK_SIZE (WORDS_STACK_SIZE*4) + + +/// \note MUST REMAIN UNCHANGED: \b osFeature_xxx shall be consistent in every CMSIS-RTOS. +#define osFeature_MainThread 1 ///< main thread 1=main can be thread, 0=not available +#define osFeature_Pool 1 ///< Memory Pools: 1=available, 0=not available +#define osFeature_MailQ 1 ///< Mail Queues: 1=available, 0=not available +#define osFeature_MessageQ 1 ///< Message Queues: 1=available, 0=not available +#define osFeature_Signals 16 ///< maximum number of Signal Flags available per thread +#define osFeature_Semaphore 65535 ///< maximum count for \ref osSemaphoreCreate function +#define osFeature_Wait 0 ///< osWait function: 1=available, 0=not available + +#if defined (__CC_ARM) +#define os_InRegs __value_in_regs // Compiler specific: force struct in registers +#else +#define os_InRegs +#endif + +#include <stdint.h> +#include <stddef.h> + +#ifdef __cplusplus +extern "C" +{ +#endif + +#include "os_tcb.h" + +// ==== Enumeration, structures, defines ==== + +/// Priority used for thread control. +/// \note MUST REMAIN UNCHANGED: \b osPriority shall be consistent in every CMSIS-RTOS. +typedef enum { + osPriorityIdle = -3, ///< priority: idle (lowest) + osPriorityLow = -2, ///< priority: low + osPriorityBelowNormal = -1, ///< priority: below normal + osPriorityNormal = 0, ///< priority: normal (default) + osPriorityAboveNormal = +1, ///< priority: above normal + osPriorityHigh = +2, ///< priority: high + osPriorityRealtime = +3, ///< priority: realtime (highest) + osPriorityError = 0x84 ///< system cannot determine priority or thread has illegal priority +} osPriority;
