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...
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 (...
Posted on January 21, 2015 at 18:13Dear All, I know that the question about jumping to the bootloader of STM32 without boot0/1 has been answered many time especially by clive1. My goal is to reprogram STM32F4 from the attached external NAND memory (...
