Hello folks,Anyone knows the default CAN clock frequency on STM32H753 MCU when powered on, assuming the CAN bit timing register (CAN_BTR) was not set by FW during the initialization?If this value would be a random, could it be changed depending on re...
Hello comunity, I am using the CMSIS DSP library in order to perform FFT to 1412 sample set with a sampling freq of 16.83Khz. I am trying different approaches to find the 16th harmonic after the fft, but i get an inaccurate value. for example, Zero-p...
I USE STM32CubeIDE Version: 1.16.0 when build the project massage arm-none-eabi-size and the hex elf or bin files after download to stm32f107vct6 no actions nothing also i use cubemx last ver for generation code thanks
Hello everyone! I have a very important question about a PCB design that I'm making.I basically have a PCB with a bunch of sensors, a 4Gb eMMC memory and a USB-C connector. Here's the related schematics : - Power section : - Microcontroller (I'm sorr...
Hiwhat is the relationship between the speed of the CPU and the GPIO response. for example, I have a CPU clock of 72MHz and a GPIO clock of 36MHz and I set the pull-up when is this pull-up visible to the CPU because e.g. I would like to read the port...
Good morning,I have an application based on the STM32L475 device that is running in many devices since many years ago. We have observed that, sometimes, some of the devices are resetted --> Here you have the main specs of my device:- Device is workin...
Hi I wanted to make a flight controller using stm32h723zgt6. My question is can this MCU have Usb virtual com port so I can use dfu Mode
The following code didn't worked because of a missing data barrier before writing to the backup SRAM:HAL_PWR_EnableBkUpAccess(); std::copy(buffer, buffer + num_bytes, BaseAddress + address); HAL_PWR_DisableBkUpAccess();Adding a DSB, solved the issue ...
Hi, I am troubleshooting a custom board using USBPD as sink. It only negotiates a PDO on one orientation of the USBC connector.Checked with an oscilloscope and I see waveform going to CC1 on the orientation that works , naturally, and changing orient...
I've setup an STM32F407 as a CDC Host on the HS peripheral with Full Speed (FS) comms, but the IN transaction always returns a NAK and no Device data is received on the Bulk Data pipe. I used the USB Host example from ST.com (userfunction that only t...
