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...
Hi, I have an example that correctly responds to ping 192.168.0.100 on the NUCLO-H743ZI demo board and where the core works at 64Mhz.If I bring the core to 400Mhz, (only this change), the program no longer works. Why ?Thank youAlberto.PS.I attach com...
Hello, I'm testing RTOS Message queue on STM32F7, When I try to create an message queue to send an message from Thread 1 to another thread, my data I receive in target Thread is unstable.For example, I'm trying to send uint16_t 317, but in target Thr...
Dear everyone,Here is my problem about the usbhost+MSC+Fatfs function with stm32cubemx in MCU stm32F407 and stm32L475, with a very strange issue:There is a bug about the f_write or f_f_sync, the operation and result is as followed:First test:1. ...
I tested the example in STM32Cube_FW_H7_V1.7.0/Projects/NUCLEO-H745ZI-Q/Templates_LL. It works perfectly on my Nucleo board.However, when I want to test my STM32H755 with the same code. The CM7 main blocked at while((LL_RCC_D2CK_IsReady() != 0) && ...
Our team has noticed that with a stock STM32F722RE, and 0.4V applied to the VDD pins (which is occuring in our case due to a 3.3v CAN transceiver), when 3.3V is finally applied to the chip (ie voltage goes from 0.4->3.3V), bootloader entry via USB co...
For PTP implementation in STM32F427 we have decided to use PTPd stack but I am not able to understand what is the use of Ethernet PTP target time high and low registers in achieving time synchronization.
We' re planning to implement ST-Link (USB to SWDIO) HW design using STM32F103CBT6 microcontroller. This HW design is similar to any STM32 Nucleo board's ST-link HW design. What I understood is STM32 controller will be having default UART bootloader ...
I am using the STM32L496VGT (100 pin) MCU and using USB_OTG_FS_DP and USB_OTG_FS_DM for data transmission. If I set the GPIO pull up for these pins (PA11 and PA12), will that act as the required pull up for the USB?
Hello guys,We have an RNDIS code that we use with STM32F070. We are trying to adapt this code to STM32F107. However, we could not find the equivalent of the code snippet below in STM32F107. Could you help? (We are using Cubemx.) #define RNDIS_CONTROL...
Hi,I would like to use a STM32F4 as a USB storage and followed the STM's video on the subject : https://www.youtube.com/watch?v=GjQqZd1keBo&.My code run fine but my PC (Win10) fail to recognize device as an USB.I used a Nucleo STM32F411RE and connec...
