+# RT-Thread based Software Package Development Guide

+

+-> RT-Thread online packages
+    -> system packages
+        --- CherryUSB: tiny and portable USB stack for embedded system with USB IP
+
+            CherryUSB Options  ---->

+                    [ ]   Enable usb audio device

+
+            Version (latest)  --->
+```
+
+## Based ON STM32 Platform
+
+Please note that stm32 series have two usb ip. For usb ip, like stm32f0、stm32f1、stm32f3, for usb otg ip(as we know it is from **synopsys**),like stm32f4、stm32f7 and so on.
+
+### Use USB Device
+
+- Firstly,you should have a bsp project,and then go to `board\CubeMX_Config` directory, open file that suffix name with `.ioc` in **STM32CubeMX**.
+- Enable **USB** or **USB_OTG_FS** or **USB_OTG_HS** in **Connectivity** List,enable USB IRQ in **NVIC Setting**.
+
+![STM32CubeMX USB setting](img/stm32cubemx.png)
+
+- Enable USB Clock for 48Mhz in **Clock configuration**.
+
+![STM32CubeMX USB clock](img/stm32cubemx_clk.png)
+
+- Generate code.
+- Copy **SystemClock_Config** into **board.c**.
+- ~~Copy **MX_USB_OTG_FS_PCD_Init** or **MX_USB_OTG_HS_PCD_Init** into **main.c** if you use **usb_dc_hal.c**.Also, USB Irq from **it.c** needs the same.~~
+- Implement **usb_dc_low_level_init** and copy codes in from ``HAL_PCD_MspInit``.
+
+```
+void usb_dc_low_level_init(void)
+{
+    /* Peripheral clock enable */
+    __HAL_RCC_USB_CLK_ENABLE();
+    /* USB interrupt Init */
+    HAL_NVIC_SetPriority(USB_LP_CAN1_RX0_IRQn, 0, 0);
+    HAL_NVIC_EnableIRQ(USB_LP_CAN1_RX0_IRQn);
+
+}
+```
+
+- Implement **printf** or modify with **rt_kprintf** in **usb_utils.h**, usb stack needs.
+- Now we can call some functions provided by **usb_stack**.Your should register descriptors、interfaces and endpoint callback firstly, and then call `usb_dc_init`. Example is as follows:
+
+```
+int main(void)
+{
+    extern void cdc_init(void);
+    cdc_init();
+    usb_dc_init();
+    while (1)
+    {
+        uint8_t data_buffer[10] = { 0x31, 0x32, 0x33, 0x34, 0x35, 0x31, 0x32, 0x33, 0x34, 0x35 };
+        usbd_ep_write(0x81, data_buffer, 10, NULL);
+        rt_thread_mdelay(500);
+    }
+}
+```
+
+- How to register class you can go to [stm32 class examples](https://github.com/sakumisu/usb_stack/tree/master/demo/stm32/stm32f103c8t6/example) for a reference.

+
+            CherryUSB Options  ---->

+
+            Version (latest)  --->
+```
+
+## 基于 STM32 平台
+
+STM32 系列单片机有两种 USB IP,分别是 USB IP 和 USB OTG IP。其中 USB IP，例如 STM32F0、STM32F1、STM32F3等等，USB OTG IP(我们都知道用的是 **synopsys** 公司的)的有 STM32F4、STM32F7、STM32H7等等。当前如果你需要使用 USB Device 功能，porting 接口提供了两种，一种是适配 USB IP的 **fsdev**,另一种是适配 USB OTG IP 的 **synopsys**。
+
+### 使用 USB Device 功能
+
+- 首先，你需要有一个 bsp 工程，之后进入到 `board\CubeMX_Config` 目录下，使用 **STM32CubeMX** 打开后缀名为 `.ioc` 的文件。
+- 进入 **Connectivity** 选项，选择 **USB** 或者 **USB_OTG_FS** 或者 **USB_OTG_HS**，并使能 device 功能，在 **NVIC Setting** 中开启 USB 中断。
+
+![STM32CubeMX USB setting](img/stm32cubemx.png)
+
+- 在 **Clock configuration** 栏配置 USB 时钟为 48Mhz.
+
+![STM32CubeMX USB clock](img/stm32cubemx_clk.png)
+
+- 点击 **Generate code**。
+- 复制 **SystemClock_Config** 函数内容到 **board.c** 中。
+- 实现 ``usb_dc_low_level_init``，并将 ``HAL_PCD_MspInit`` 里面内容复制进来，例如：
+
+```
+void usb_dc_low_level_init(void)
+{
+    /* Peripheral clock enable */
+    __HAL_RCC_USB_CLK_ENABLE();
+    /* USB interrupt Init */
+    HAL_NVIC_SetPriority(USB_LP_CAN1_RX0_IRQn, 0, 0);
+    HAL_NVIC_EnableIRQ(USB_LP_CAN1_RX0_IRQn);
+
+}
+```
+
+- 由于协议栈默认使用 `printf` 和 `malloc` 和 `free`,所以需要开启 libc 支持或者自己实现。
+![libc](img/rtt_libc.png)
+
+- 使用 **menuconfig** 配置 **CherryUSB** 软件包，使能 usb device 并勾选需要的 device class。
+![usb host](img/rtt_menuconfig1.png)
+
+- 现在我们可以调用 CherryUSB 中的函数来注册描述符、接口、端点中断，并调用 `usb_dc_init`，示例如下：
+
+```
+#include <rtthread.h>
+#include <rtdevice.h>
+#include <board.h>
+#include <stdio.h>
+
+extern void usb_dc_init(void);
+int main(void)
+{
+    extern void cdc_init(void);
+    cdc_init();
+    usb_dc_init();
+    while (1)
+    {
+        uint8_t data_buffer[10] = { 0x31, 0x32, 0x33, 0x34, 0x35, 0x31, 0x32, 0x33, 0x34, 0x35 };
+        usbd_ep_write(0x81, data_buffer, 10, NULL);
+        rt_thread_mdelay(500);
+    }
+}
+
+```
+
+- 关于如何注册 class 类可以参考 [stm32 class examples](https://github.com/sakumisu/usb_stack/tree/master/demo/stm32/stm32f103c8t6/example)。
+
+### 使用 USB Host 功能
+
+- 首先，你需要有一个 bsp 工程，之后进入到 `board\CubeMX_Config` 目录下，使用 **STM32CubeMX** 打开后缀名为 `.ioc` 的文件。
+- 进入 **Connectivity** 选项，选择 **USB_OTG_FS** 或者 **USB_OTG_HS**，并使能 **host only** 功能，在 **NVIC Setting** 中开启 OTG GLOBAL 中断，其余两个端点中断不需要。
+
+![STM32CubeMX USB setting](img/stm32cubemx2.png)
+
+- 在 **Clock configuration** 栏配置 USB 时钟为 48Mhz.
+- 点击 **Generate code**。
+- 复制 **SystemClock_Config** 函数内容到 **board.c** 中。
+- 修改 **usb_hc_synopsys.c** 中 HAL 库头文件包含，例如 `#include "stm32f4xx_hal.h"`。
+- 手动增加 **xxx_hal_hcd.c** 和 **xxx_ll_usb.c** 文件
+- 由于协议栈默认使用 `printf` 和 `malloc` 和 `free`,所以需要开启 libc 支持或者自己实现。
+![libc](img/rtt_libc.png)
+
+- 使用 **menuconfig** 配置 **CherryUSB** 软件包，使能 usb host（默认加载所有支持的 class）。
+![usb host](img/rtt_menuconfig2.png)
+
+- `main.c` 中调用 `usbh_initialize` 初始化 host 协议栈。
+
+```
+#include <rtthread.h>
+#include <rtdevice.h>
+#include <board.h>
+#include "usbh_core.h"
+/* defined the LED0 pin: PH10 */
+#define LED0_PIN    GET_PIN(H, 10)
+
+int main(void)
+{
+    /* set LED0 pin mode to output */
+    rt_pin_mode(LED0_PIN, PIN_MODE_OUTPUT);
+    usbh_initialize();
+    while (1)
+    {
+        rt_pin_write(LED0_PIN, PIN_HIGH);
+        rt_thread_mdelay(500);
+        rt_pin_write(LED0_PIN, PIN_LOW);
+        rt_thread_mdelay(500);
+    }
+}
+
+
+```
