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 24, 2015 at 19:24Hello! I try port stm32 4x9I-eval LwIP application ( LwIP_HTTP_Server_Raw ) to stm32 429I-disco. In F.A.Q. said that:''When another hardware platform is used, check the GPIO configuration in the HAL_ETH_MspInit()...
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 20, 2015 at 13:49I'm hoping this is my last Report Descriptor question. As I found out, the HS USB DMA in the '405 only has access to RAM memory locations. With this in mind, I copy the Report Descriptor to RAM from it's original ...
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 February 16, 2015 at 09:50Hello, I have following problem, when I deinited PB4, using HAL_GPIO_DeInit function I lose the interrupt on PA4 pin. Reason: resetting SYSCFG->EXTICR[] values without checking port sources! LIbs: STM32Cube_FW_F4...
Posted on February 19, 2015 at 14:00I've implemented a USB-HID device, based on the example provided by ST (STM32_USB-FS-Device_Lib_V4.0.0\Projects\Custom_HID).The project requires I use a VID which is not STM's, so I aquired a VID from usb.org, and...
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...
