# ZEPHYR example介绍 https://docs.zephyrproject.org/latest/samples/sample_definition_and_criteria.html ## sample_definition_and_criteria sample 样例的标准和定义 ## class Sample 经典样例， 可以运行在任意平台 - [Hello World](https://docs.zephyrproject.org/latest/samples/hello_world/README.html) 最简单的hello world - [Synchronization Sample](https://docs.zephyrproject.org/latest/samples/synchronization/README.html) 线程同步问题 - [Dining Philosophers](https://docs.zephyrproject.org/latest/samples/philosophers/README.html) 哲学家就餐问题 ## basic sample 基本sample - [Blinky](https://docs.zephyrproject.org/latest/samples/basic/blinky/README.html) LED 灯闪烁 - [PWM Blinky](https://docs.zephyrproject.org/latest/samples/basic/blinky_pwm/README.html) 用PWM 进行LED灯闪烁 - [Button](https://docs.zephyrproject.org/latest/samples/basic/button/README.html) 一个简单的按钮演示，展示了 GPIO 输入和中断的使用。每次按下按钮时，该示例都会向控制台打印一条消息。 - [GPIO with custom devicetree binding](https://docs.zephyrproject.org/latest/samples/basic/custom_dts_binding/README.html) 在 Zephyr 中，所有特定于硬件的配置都在设备树中描述。 因此，GPIO 引脚也在设备树中进行配置，并使用兼容分配给特定用途。 这与 Arduino 等其他嵌入式环境形成鲜明对比，其中 GPIO 引脚的方向（输入/输出）是在应用程序固件中配置的。 对于 LED 或按钮等典型用例，可以使用现有的[`gpio-leds`](https://docs.zephyrproject.org/latest/build/dts/api/bindings/led/gpio-leds.html#std-dtcompatible-gpio-leds)或 兼容的。[`gpio-keys`](https://docs.zephyrproject.org/latest/build/dts/api/bindings/input/gpio-keys.html#std-dtcompatible-gpio-keys) 此示例演示了如何通过自定义设备树绑定将 GPIO 引脚用于其他目的。 - [Fade LED](https://docs.zephyrproject.org/latest/samples/basic/fade_led/README.html) LED 开始时会增加其亮度，直到完全或接近完全亮起。然后亮度逐渐降低，直至 LED 关闭，完成淡入淡出循环。每个循环需要 2.5 秒，并且循环会永远重复。PWM 周期取自 Devicetree。它应该足够快以高于闪烁融合阈值。 - [System Hashmap](https://docs.zephyrproject.org/latest/samples/basic/hash_map/README.html) 系统哈希图 这是一个简单的例子，反复 - 插入最多`CONFIG_TEST_LIB_HASH_MAP_MAX_ENTRIES` - 最多替换先前插入的相同数字 - 删除所有先前插入的键 - [Minimal footprint](https://docs.zephyrproject.org/latest/samples/basic/minimal/README.html) 占地面积最小 概述 此示例提供了一个空的main()各种配置文件，可用于测量 Zephyr 在不同配置中的最小 ROM 占用空间。 - [PWM: RGB LED](https://docs.zephyrproject.org/latest/samples/basic/rgb_led/README.html) 脉宽调制：RGB LED 概述 这是一个使用 PWM 驱动 RGB LED 的示例应用程序。 RGB LED 中有 3 个单色 LED。每个 LED 组件均由 PWM 端口驱动，其中脉冲宽度从零更改为 Devicetree 中指示的周期。该周期应足够快，以高于闪烁融合阈值（LED 被感知为稳定的最小闪烁率）。该示例使每个 LED 组件从黑暗变为最大亮度。三个for循环（每个 LED 组件一个）从 RGB LED 生成一系列逐渐变化的颜色，并且示例将永远重复。 - [Servomotor](https://docs.zephyrproject.org/latest/samples/basic/servo_motor/README.html) 伺服电机 概述 这是一个使用 PWM 驱动伺服电机的示例应用程序。 该示例通过 PWM 控制信号使伺服电机在 180 度范围内来回旋转。 该应用程序针对伺服电机 ROB-09065。0 至 180 度范围内相应的 PWM 脉冲宽度分别为 700 至 2300 微秒。不同的伺服电机可能需要不同的 PWM 脉冲宽度，如果使用不同的伺服电机，您可能需要修改源代码。 - [System heap](https://docs.zephyrproject.org/latest/samples/basic/sys_heap/README.html) 系统堆 概述 一个简单的示例，可与任何支持的板一起使用，并将系统堆使用情况打印到控制台。 - [Basic Thread Example](https://docs.zephyrproject.org/latest/samples/basic/threads/README.html) 基本线程示例 概述 此示例演示了使用 生成多个线程 K_THREAD_DEFINE()。它产生三个线程。然后在编译时使用 K_THREAD_DEFINE 定义每个线程。 前两个分别控制一个 LED。这些 LEDled0和led1具有由单独功能控制的循环控制和定时逻辑。 blink0()控制led0并具有 100ms 的睡眠周期 blink1()控制led1并具有 1000ms 的睡眠周期 当这些线程中的任何一个线程切换其 LED 时，它还会将信息推送到 FIFO中，以识别线程/LED 以及已切换的次数。 第三个线程用于printk()将添加到 FIFO 的信息打印到设备控制台。 ## USER SPACE - [Hello World](https://docs.zephyrproject.org/latest/samples/userspace/hello_world_user/README.html) 你好世界 概述 一个简单的 Hello World 示例，可与任何支持的板一起使用并打印“Hello World from UserSpace!” 到控制台。如果不可用或未配置，则“特权模式下的 Hello World”。而是打印出来。 - [Producer/consumer](https://docs.zephyrproject.org/latest/samples/userspace/prod_consumer/README.html) 生产者/消费者 这是一个练习一些用户模式概念的示例应用程序。 概述 考虑一个“示例驱动程序”，它从某个未知源获取传入数据，并生成带有指向该数据的指针的中断。应用程序需要对此数据执行一些处理，然后将处理后的数据写回驱动程序。 这里的目标是证明： 多个逻辑应用程序，每个应用程序都有自己的内存域 创建 sys_heap 并分配给内存分区 使用k_queue_alloc_append()需要配置线程资源池的API 内核对象和驱动程序的权限管理 显示如何定义特定于应用程序的系统调用 显示 ISR 和应用程序之间的 IPC（使用k_msgq）以及应用程序到应用程序的 IPC（使用k_queue） 展示如何创建特定于应用程序的系统调用 - [Userspace Protected Memory](https://docs.zephyrproject.org/latest/samples/userspace/shared_mem/README.html) 用户空间保护内存 概述 此示例是运行分配有受保护分区的唯一内存域的多个线程的示例。该应用程序使用内存分区和模拟类似谜机的示例算法，但该机器的实现尚未经过验证，不应用于任何实际的安全目的。 要求 该示例依赖于子系统app_memory，并且它不会在不支持该子系统的主板上运行。该示例在以下板子 qemu_x86、frdm_k64、96b_carbon 上进行了测试。 - [Syscall performances](https://docs.zephyrproject.org/latest/samples/userspace/syscall_perf/README.html) 系统调用性能 此示例应用程序的目标是测量与直接调用函数的主管线程相比，用户线程必须经过系统调用时的性能损失。 概述 该应用程序创建一个主管和一个用户线程。然后两个线程都调用 k_current_get() 返回当前线程的引用。用户线程必须经过系统调用。 两个线程都显示调用 k_current_get() 时的核心时钟周期数和执行的指令数。 ## subsys -
