The specific path is as follows: - -``` --> RT-Thread online packages - -> system packages - --- CherryUSB: tiny and portable USB stack for embedded system with USB IP - - CherryUSB Options ----> - USB Speed (FS) ---> - [*] Enable usb device mode - [*] Enable usb cdc acm device - [ ] Enable usb hid device - [ ] Enable usb dfu device - [ ] Enable usb msc device - [ ] Enable usb hub device - [ ] Enable usb audio device - [ ] Enable usb video 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**. - - - -- Enable USB Clock for 48Mhz in **Clock configuration**. - - - -- 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. - -### CDC Demo Demonstration - - - -### Video manual - -If you have problem from steps above, you can see this video：[Use USB Stack in RT-Thread package manager](https://www.bilibili.com/video/BV1Ef4y1t73d?p=26)。
