FreeRTOSConfig.h
FreeRTOS is customised using a configuration file called FreeRTOSConfig.h. Every FreeRTOS application must have a FreeRTOSConfig.h header file in its pre-processor include path. FreeRTOSConfig.h tailors the RTOS kernel to the application being built. It is therefore specific to the application, not the RTOS, and should be located in an application directory, not in one of the RTOS kernel source code directories.
Each demo application included in the RTOS source code download has its own FreeRTOSConfig.h file. Some of the demos are quite old and do not contain all the available configuration options. Configuration options that are omitted are set to a default value within an RTOS source file.
Here is a typical FreeRTOSConfig.h definition, followed by an explanation of each parameter
FreeRTOS 使用名为 FreeRTOSConfig.h 的配置文件进行自定义。 每一个 FreeRTOS 应用程序的预处理器中必须有 FreeRTOSConfig.h 头文件 包括路径。 FreeRTOSConfig.h 为正在运行的应用程序定制 RTOS 内核 建成。 因此，它特定于应用程序，而不是 RTOS，并且应该是 位于应用程序目录中，而不是在 RTOS 内核源代码之一中的目录。
RTOS 源代码下载中包含的每个演示应用程序都有自己的 FreeRTOSConfig.h 文件。 一些演示很老，不包含所有可用的配置选项。 省略的配置选项 在 RTOS 源文件中设置为默认值。
这是一个典型的 FreeRTOSConfig.h 定义，后面是每个的解释 范围：

configUSE_IDLE_HOOK
Set to 1 if you wish to use an idle hook, or 0 to omit an idle hook.
如果希望使用空闲挂钩，请将其设置为1；如果希望省略空闲挂钩，请将其设置为0。
configUSE_TICK_HOOK

configCPU_CLOCK_HZ
Enter the frequency in Hz at which the
internal
clock that drives the peripheral used to generate the tick interrupt will be executing – this is normally the same clock that drives the internal CPU clock. This value is required in order to correctly configure timer peripherals.输入驱动用于生成勾选中断的外围设备的内部时钟将执行的频率（以Hz为单位），该频率通常与驱动内部CPU时钟的时钟相同。要正确配置计时器外围设备，需要此值。
configTICK_RATE_HZ
The frequency of the RTOS tick interrupt.
RTOS滴答中断的频率。
configMAX_PRIORITIES
The number of priorities available to the application tasks.
应用程序任务可用的优先级数。
configMINIMAL_STACK_SIZE
The size of the stack used by the idle task.
空闲任务使用的堆栈的大小。
configTOTAL_HEAP_SIZE
configMAX_TASK_NAME_LEN
The maximum permissible length of the descriptive name given to a task when the task is created. The length is specified in the number of characters including the NULL termination byte.
创建任务时赋予任务的描述性名称的最大允许长度。长度以包括空终止字节在内的字符数指定。
configUSE_TRACE_FACILITY
Set to 1 if you wish to include additional structure members and functions to assist with execution visualisation and tracing.
如果希望包含其他结构成员和功能，以协助执行可视化和跟踪，请设置为1。
configUSE_16_BIT_TICKS
Time is measured in ‘ticks’ – which is the number of times the tick interrupt has executed since the RTOS kernel was started. The tick count is held in a variable of type TickType_t.
Defining configUSE_16_BIT_TICKS as 1 causes TickType_t to be defined (typedef’ed) as an unsigned 16bit type. Defining configUSE_16_BIT_TICKS as 0 causes TickType_t to be defined (typedef’ed) as an unsigned 32bit type.
Using a 16 bit type will greatly improve performance on 8 and 16 bit architectures, but limits the maximum specifiable time period to 65535 ‘ticks’. Therefore, assuming a tick frequency of 250Hz, the maximum time a task can delay or block when a 16bit counter is used is 262 seconds, compared to 17179869 seconds when using a 32bit counter.
时间是以“滴答”来衡量的——这是自RTOS内核启动以来滴答声中断执行的次数。滴答计数保存在TickType_t类型的变量中。
将configUSE_16_BIT_TICKS定义为1会将TickType_t定义为（typedef’ed）无符号16位类型。将configUSE_16_BIT_TICKS定义为0会将TickType_t定义为（typedef’ed）无符号32位类型。
使用16位类型将大大提高8位和16位体系结构上的性能，但将最大指定时间段限制为65535个“滴答”。因此，假设滴答频率为250Hz，当使用16位计数器时，任务可以延迟或阻止的最长时间为262秒，而使用32位计数器时为17179869秒。
configUSE_PREEMPTION
Set to 1 to use the preemptive RTOS scheduler, or 0 to use the cooperative RTOS scheduler.
设置为1以使用抢占式RTOS调度程序，或设置为0以使用协作式RTOS调度程序。
configUSE_TIME_SLICING
By default (if configUSE_TIME_SLICING is not defined, or if configUSE_TIME_SLICING is defined as 1) FreeRTOS uses prioritised preemptive scheduling with time slicing. That means the RTOS scheduler will always run the highest priority task that is in the Ready state, and will switch between tasks of equal priority on every RTOS tick interrupt. If configUSE_TIME_SLICING is set to 0 then the RTOS scheduler will still run the highest priority task that is in the Ready state, but will not switch between tasks of equal priority just because a tick interrupt has occurred.
默认情况下（如果未定义configUSE_TIME_SLICING，或者如果configUSE_TIME_SLICING定义为1），FreeRTOS使用优先抢占式时间切片调度。这意味着RTOS调度程序将始终运行处于就绪状态的最高优先级任务，并在每个RTOS时钟中断时在同等优先级的任务之间切换。如果configUSE_TIME_SLICING设置为0，则RTOS调度程序仍将运行处于就绪状态的最高优先级任务，但不会仅因为发生了勾号中断而在同等优先级的任务之间切换。
configIDLE_SHOULD_YIELD
This parameter controls the behaviour of tasks at the idle priority. It only has an effect if:
The preemptive scheduler is being used.
The application creates tasks that run at the idle priority.此参数控制空闲优先级下任务的行为。它只有在以下情况下才有效：
正在使用抢占式调度程序。
应用程序创建以空闲优先级运行的任务。
configUSE_CO_ROUTINES
Set to 1 to include co-routine functionality in the build, or 0 to omit co-routine functionality from the build. To include co-routines croutine.c must be included in the project.
设置为1可在生成中包含协同例程功能，设置为0可在生成中忽略协同例程功能。包括croutine.c必须包含在项目中。
configMAX_CO_ROUTINE_PRIORITIES
The number of
priorities
available to the application co-routines. Any number of co-routines can share the same priority. Tasks are prioritised separately – see configMAX_PRIORITIES.应用程序协同例程可用的优先级数。任意数量的共同例程可以共享相同的优先级。任务的优先级是分开的-请参阅configMAX_PRIORITIES。
