To test our USB communication, we will do a simple echo device.

If we build&upload the code, Device Manager shows “USB Serial Device (COMx)” under “Ports (COM & LPT)”. usbd_cdc.h contains CDC packet/endpoint sizes Category: FPV Essentials By GetFPV SeptemLeave a comment. Installing Betaflight Walkthrough GitHub Page. I’m following the instructions on the betaflight website, but they get it to work and I cannot. It looks like the driver installs properly (no errors), but it isn’t showing up in the betaflight configurator (it should show up as COM 3, but doesn’t).

Note: Endpoint naming is host-based meaning, on our STM32, IN endpoint actually means data direction from uC to PC (PC IN endpoint). Looking for where to download the Betaflight Configurator or the drivers mentioned in the video We’ll help you get to the right place Betaflight Configurator GitHub Page. I just installed betaflight and am trying to add the STM USB VCP driver. Endpoints could be seen as buffers inside devices, that have a specific purpose. OS versions prior to Windows ® 7 are compatible with the Windows ® 7 installations included in the package.

c file, generated CDC contains 2 data endpoints (IN and OUT) and 1 control endpoint. Description Compatible with the x86 and 圆4 platforms The STSW-STM32102 software package contains four installation files based on the various versions of the Microsoft ® operating system. I try to implement USB CDC FS on the discovery Board from STM. You don’t really need to change anything for now, but there are many descriptor fields that can be modified.Īs it is stated at the top of the. Maybe the virtual com port driver cannot buffer the high amount of data they are comeing from the MCU Youll need the ST USB library STM32 USB-Host-Device Lib V2.1.0 and the standard peripheral libraries. This is set with CubeMX so don’t change this defines. USB configuration defines in usbd_conf.h.More about file hierarchy can be found in STM32Cube USB device library user manual.įiles to modify CDC to our custom needs are: usbd_cdc_if.c (provides application read/write functions).usbd_desc.c (provides USB device descriptors).
usbd_ioreq.c, usbd_ctlreq.c (provides everything for endpoint controls and USB request).usbd_core.c (provides all USB device core functions).More about endpoints later.Īgain, USB files contains “settings for CDC” in this files: To generate basic USB CDC device with CubeMX, follow this previous post, but change Middleware USB profile to CDC. So, here it is, STM32 USB CDC – communication with PC over USB, generated with STM32CubeMX on STM32L100 discovery board. Although this devices were mostly prototypes and/or single products, such approach added unwanted costs and since almost all uC that I used already have USB peripheral embedded, there is no excuse not to use it. By now almost all of my projects included some sort of communication with PC, mostly with external USB-UART bridge chip like MCP2200 or CP210x.
