Add USBD_User_CDC_0.c to the project: right click on Source Group 1 and use menu option Add new item. Open file RTX_Conf_CM.C and expand all in configuration wizard.Ĭhange Main thread stack size to 512, Number of threads with user-provided stack size to 2, Total stack size for threads with user-provided stack size to 1024 and Timer clock value to 168000000.ġ3. The detailed description is in the MDK-Professional Middleware User’s Guide, section “ Resource Requirements“. Refer also to “CMSIS-RTOS RTX Configuration” in MDK5 getting started. Adjust the RTOS resources for USB device. Expand USB OTG Full-speed and enable Device. Set the High-speed external clock to 8MHz (8000000), System and AHB clock to 168MHz (168000000).ġ1. Open the file RTE_Device.h and expand Clock configuration. Open file USBD_Config_CDC_0.h and change parameters in Communication device class Settings: Buffer size to 128 bytes, Communication Class Interface String to “USB_CDC” and Data Class Interface String to “USB_CDC1”. Leave other values as they were in template:ĩ.
#Stm32 virtual comport in fs mode serial number
Change Serial number to any value you may want. Change Maximum power consumption to 500mA. Open USBD_Config_0.c, select Configuration Wizard and click Expand All. Our CDC Device example, we have two configuration files: USBD_Config_0.c and USBD_Config_CDC_0.h.Ĩ. These configuration files are accessed in the Project window.

Next step is Middleware configuration. Every MDK-Professional Middleware component has a set of configuration files that adjusts application specific parameters and determines the driver interfaces. All selected component are now in the project. Click Resolve to clean up the selections:Ĭlick OK.
#Stm32 virtual comport in fs mode drivers
Expand Drivers USB Device (API) and enable Full-speed. Set USB Device CDC to ‘1’ to create a CDC Device Class instance:ħ. Set USB Device to ‘1’ to create one USB Device instance.Ħ. From the USB Device Component select USB Core to include the basic functionality required for USB communication.ĥ. Expand the KEIL MDK Middleware and select the fixed version 5.1.5. Expand ARM CMSIS and select Fixed version 3.20.4. The new dialog will open.Ģ. Uncheck Use latest versions of all installed Software Packs.ģ. All STM32 Device Family Packs Version 1.x implement Drivers based on Version 1.x and are therefore not compatible. New and existing projects need to be configured to use the newly installed versions of the CMSIS and MDK-Middleware Packs. First select proper packs versions, click “ Select packs“:ĬMSIS Version 4.1 contains the CMSIS-Driver API Version 2, which is incompatible with Drivers Version 1. Open or continue editing the project and use the Manage Run-Time Environment dialog to add the USB device driver templates.ġ. You can copy/paste the entire folder to new one or continue inside the existing “blinky”. This application is based on LED blinky desribed in first tutorial.
