Hello,I have some strange behaviour:After adding external flash configuration to my application, the Ethernet stopped working (no ping).I validated that the following added code is responsible for this failure, but I don't understand why these config...
I am using STM32F756 Eval board and trying ADC+DMA example.Example, is about one ADC conversion and the data is stored in variable using DMA.I am looking out for changes to be done in the configuration such that,After I start ADC conversion, I must ...
Hi,I am writing a 16bit register 0x3f of i2c device connected at 0x09. After write, if I read the value of 0x3f register it is always '0'. I2C communication is working fine on device.Below is a code.#include "main.h" #define I2C_ADDRESS 0x09<<...
Hello everyone,I’m working with an MCU STM32F401 (NUCLEO Board) which receives via I2C the measurements sent by a sensor VL53L1. I would like then to be able to intervene at any time by interrupting the communication between the MCU and the sensor to...

After reading the data sheets, the Getting Started document and others, I need some clarification on connectivity of the VddUSB pin. On page 12 of AN4555, it states:"The USB transceivers are supplied from a separate VDDUSB power supply pin. VDDUSB ra...
Does anyone can provide version 1.11.0 of stm32cube fw l4?I'm using STM32CubeMX V4.25 to maintain old project,but I can't download the version by CubeMX.
On STM32F407, I set PA8 to AF, AF10, for OTG_FS_SOF. After attaching a device in HOST mode to OTG_FS, I see SOF pulses on PA8, regardless of setting of OTG_FS_GCCFG.SOFOUTEN bit.ST, please comment.JW
HiI have the F446ZE Nucleo board and am using the latest ST supplied demo code from mbed.com to use the CDC as a serial port.The code from mbed compiles without issue and downloads to the F446ZE. At that point Windows attempts to load the CDC driver...
EPENA bit for IN endpoint 0 (OTG_FS_DIEPCTL0 register) is marked as read-only both in the reference manual and in the SVD files for F429.I believe that is a mistake, as the EPENA bit is used to start transmission on the endpoint and both libopencm3 a...
