If you compile stm32f4xx_hal_pcd.c with -Wall, you will get signed/unsigned comparison warnings. Most of them seem minor, however, in line 1299 they do the following:int32_t len; .. if(len <= 0U) { fifoemptymsk = 0x1U << epnum; USBx_DEVICE->D...
Hell ST community!I have made a board with an STM32H743ZI MCU on it. It has connections to pins where serveral USART peripherals sit (without pull-ups) and uses USB FS on PA9 to PA12.My problem is that the DFU bootloader does not show up via USB. If ...
Hi, I'm fairly new to arm platform. I'm trying to communicate between 2 MCU via Canbus. with the latest HAL Library I set up 4 filters (2 for each fifo) id mask type , 32Bit. I am receiving my messages from correct fifos. what I cant get is filter ...
Hello, I am getting acquainted with FreeRTOS using HAL Libraries. For that I have created two tasks, Task 1 and Task 2 and am simply printing "Task 1" and "Task 2" over a UART. If I build the project from scratch, then I get the text, data, bss sizes...
I'm working on a Canbus project for a while now. I used rx and tx interrupts just fine, but when I enable ErrorCallback its not working. I've activated Error Interrupt by setting CAN_ IER[15] and activate notification. When I try to disrupt communica...

Hi, I'm starting to work with a Nucleo-64 with a STM32F072RBT6.I'm reading these documents and not really understandign them:https://www.st.com/content/ccc/resource/technical/document/user_manual/2f/77/25/0f/5c/38/48/80/DM00122015.pdf/files/DM0012201...
Posted on August 03, 2017 at 09:53Hi ! I'm currently looking for the best sleep mode for my device.I'm not able to find any information on Datasheets or Application Notes on the capability of wake-up a STM32L476RG via USB Bus on the Shutdown Mode.I ...
I have an STM32F4DISCOVERY with STM32F401 and I can't find any information about it since it was replaced :(I tried to use some USB device features but can't get any of them working. I'm able to compile and flash the board and the remaining periphera...
Good Morning I use STM32F1VCT with the CANOPEN_Stack of the company EMTAS. For the CAN I use PIN PB8-PB9.If the program starts normally, the CAN bus works as desired.However, if I want to debug, the debugger will abort as soon as the macro "__HAL_AFI...
