STM32F4 clock configuration tool generates code that causes USART baud rates to be 2x too fast
I am using the STM clock configuration tool STM32F4xx_ClockConfiguration_V1.10.xls to generate the system_stm32f4xx.c file for a project using a STM32F407 processor with a 16MHz HSE. I am also using the Keil MDK-ARM V5.23, and the STM32F4xx_DSP_StdP...
I am using STM32F030CCT6TR microcontroller for my Bootloader, but the while switching to application there is an error in initialization of System Clock.
I am blinking LED every 4 sec for up to 5 counts in Bootloader and switching to Application where I am blinking LED every second.But while jumping to Application the Clock Initialization is failing.
Resolved! why has PA4 (ADC1CH18) low impedance as soon as adc2 temp channel gets initialized
Hello,In our project, we are using a STM32H7B3ZI, LQFP144 package.We are using a simple 24v, 33k/2k7 voltage divider to sense a voltage and expected a voltage at this pin ~1.8V. The signal is connected to PA4, evaluated by ADC1CH18, no PU, no PD.Furt...
STM32L452RET6P VDDUSB Pin
Hi all,I'm using the STM32L452RET6P in my PCB design.I would like to use its USB Device feature and unlike some other STM32 i encoutered, it seems that here there is a special need in VDDUSB pin on the MCU.Can someone help me understand how to use th...
Resolved! STM32F407 USB audio stream problem! AUDIO_AudioCmd_FS gets called only once.
Hello everyoneI am trying to implement a simple soundcard from using STM32F407G-DISC1 board.It utilizes STM32F407. I am using CubeIDE version 1.10.1I configured the USB to be Full-speed Device Only. And I configured the middleware as Audio class.I se...
Getting started with PTP (IEEE 1588)
Hello, I want to try to use PTP in my project, but the lack of documentation took me into a dead point. I'm currently using an STM32H755 which support the protocol.I have a lot of question but as first thing I want to understand the faesability of th...
Resolved! USB HID device: IN Interrupt Endpoint does not receivce anything
Hello,I am programming a USB device from scratch (for learning purposes) on a STM32F7 board.It is a simple HID mouse.Everything works great in the enumeration, my device is correctly recognized by the host (Windows PC) as a mouse. I've chose to use a...
How can I get the embedded demonstration example for P-NUCLEO-USB002 kit?
After testing P-NUCLEO-USB002 kit with it's embedded demonstration example I try to use different example from en.STSW-STUSB010 examples- it seems like non of them support UART interface (CLI) as in P-NUCLEO-USB002 embedded demonstration example. my ...
