Hello, i am using STM32F411RE with raspberry pi 4. i want to communicate rasp with stm32 through usb cable from pi to CN1 of stm32. i want the communication both ways. could you please tell me how to do it?Thank you in advance.
I have setup Timer 8 to generate PWMs, to modulate a sinewave. I use preload, but that is only used once.I have debugged and compared the registers, but i could not find a cause. I have also partially compared the sram bytes, but i could not find the...
Subject: STM32H7 USBX Virtual COM Port Setup - Missing ux_dcd_stm32.h FileHello ST Community,I'm working on setting up a USB Virtual COM port on an STM32H7 microcontroller using Azure RTOS (AzureRTOS-H7). I'm encountering an issue with missing USBX f...
I have two questions. One is how are Y and V distinguished? The other is where can I know what channels these Direct channels and FAST channels include?
This was a tricky bug to find. I am doing context switching. Everything seems to working well until a context switch happens while one of my tasks has called a different function. Specifically, HAL_GetTick(). To be clear the switch is happening while...
I am looking at the STM32U073x8/B/C Datasheet - DS14548 - Rev 2 - March 2024. Table 12 on page 35 is a list of all the pins and which pin they are connected to on each package. The row for VDDUSB does not have a pin listed for the UFQFPN32 packag...
Hello,I have been utilizing the OTG_HS peripheral on an STM32U5A5 to act as a USB host. I am using the USBx stack in a non-secure application and initializing the peripheral as follows: VOID USBX_APP_Host_Init(VOID) { MX_USB_HCD_Init(); ux_host...
Hi all,I am working on a motor control project using STM32, and I am trying to calculate the RPM of a BLDC motor using Hall sensor pulses. I have set up a SysTick timer to trigger an interrupt every 1 millisecond, which should increment a counter (sy...
Hi guys, I m having an issue with my Nucleo F401RE. I m porting a code based on the use of SPI2 that worked very well on Nucleo G431RB. I made same setting on Nucleo IDE (see picture). After inizialization of periperhals NSS (Chip Select) goes to hig...
Hello ALL,ADC values when 2 channel are disturbed when used in STM32L071 board. i have tried changing the sampling time of channels still no difference the voltage at that pin is around 2.5 volt but the ADC value after conversion i am receiving is ar...
