Hello?I am using a 3-phase 380V induction motor drive application, and the MCU is STM32F401VCT6. I am using it at 56MHz.The USB memory storage function is being used, but as soon as it operates, the system all stops operation. Because watchdog (IWDG)...
The data frame of BootLoader of STM32F207 : a start bit, data bits, even parity bit and a stop bit.The USART data contains a even parity to send to the BootLoader, then it replies with the correct data.Theoretically, USART data has no parity bit, th...
Couldn't find a "general questions" category, so goes here...I've registered to STM webinar Accelerating STM32 application development with new STM32Cube Tools on Sep. 22 . I received a "Webinar login information" which has no login but only yet ag...
Hi,Recently we developed a on the fly Firmware update system using the L4 series MCU's.There it worked by setting the BFB2 bit and reading the FB_MODE bit to determine which bank was booted and where the code needed to be erased and written.Now we ar...
I'm struggling to get a composite HID device to work properly.I started from the Mouse HID device and built a basic example. Mouse by itself works. Then I modified that example to impersonate a joystick. and that works, too.Then I create a composite ...
I am working on STM32F411 discovery kit configured as USB Host to a Power device.The power device that I use is APC UPS. The task is to read various parameters of UPS over USB by the STM. I use USBH_HID_GetReport function call with appropriate report...
Hello,About a year ago, I created my own project UDP_SERVER using STM32CubeMX. Everything worked until I upgraded HAL_Driver from 11.09.2020 ( V 1.25.1 ). My program stopped working properly.I searched for a reason for many days. This annoying chang...
Hey all,I'm new to MCU programming. Right now I'm looking into starting interaction with STM32F407VG via a USB port. My simple understanding is I've got to create a piece of code allowing the MCU to pretend to be a device with a specific VID (1234) a...
Hi!I want to transmit data synchronously (near real time) from ADC using DMA half- and full transfer interrupts.I created an example project for NUCLEO-F429ZI using the LWIP RAW API. I don’t want to use any RTOS because I want to learn and understand...
