Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Posted on February 26, 2015 at 11:11The function HAL_CAN_ConfigFilter() takes as a parameter CAN_HandleTypeDef* hcan (a handle) but inside the function will be used a fixed CAN1. Line 370: /* Initialisation mode for the filter */ CAN1->FMR |= (u...
Posted on September 14, 2012 at 10:40HiWe are developing an audio application with the stm32F405RG that streams the audio from the host asynchronously as a full speed device.Our problem is that we keep loosing feedback packets (24 bit values) and we...
Posted on June 10, 2014 at 09:05Hi all,I'm modifying the VCP demo for STM32F207 to work without VBUS sensing, just using D+/D- for USB communications. As stated in RM0033 (page 935/1334 Doc ID 15403 Rev 5, chapter 29.5 USB peripheral): �The VBUS pin...
Posted on February 06, 2015 at 13:32I've got a STM32F405 using a Microchip USB3300 PHY set up to run as a HS HID USB device. The device gets MOST of the way through enumeration. However, when the host queries for the report descriptor, the device fa...
Posted on February 18, 2015 at 10:27Hi,I'm using the USB Host library 2.1.0 (with USB_OTG_FS) on an STM32F401CD. Using the USB CDC code I'm having the following issue:When the STM32 is connected to a PC but no application on the PC has the port open...
Posted on August 11, 2014 at 18:28Is there any description of HAL library for STM32F2s.I found the UM1725 documentation but only applies for STM32F4s.Anything similar for STM32F2s???Thanks, #stm32f2 #hal-library
Posted on February 19, 2015 at 08:25The example provided for Virtual COM over USB (STM32_USB-FS-Device_Lib_V4.0.0\Projects\Virtual_COM_Port) does not include UART flow control. The UART module is hard-coded to not use CTS/RTS, and when the UART-->US...
Posted on January 30, 2015 at 15:53I am just integrating new STMcube for my project on STM32F4. I want to use DMA on USART1 without any interrupt. But i had a look at STMCube library, It uses Interrupts in DMA. Any thoughts how can i make DMA work...
Posted on February 18, 2015 at 14:44Hey all,I'm trying to implement a USB CDC device on an STM32F072B-Discovery (uses the STM32F072RBT6 device) to simply send some values over to the serial console. I've not had much luck with this using the code ge...
Posted on February 12, 2015 at 13:23Hi, I use the USB VCP (based on VirtualComport_Loopback) in STM32L152VE. I disabled suspend (''__IO bool fSuspendEnabled = FALSE;'' in usb_pwr.c). If the USB cable is disconnected I get endless suspend interrups (...
