STM32 MCUs Products

Need to read the encoder signals with frequency 1.8MHz using timer input capture using STM32H743 Eval board.

I have configured the TIM3 in input capture with following configurationPrescale - 1Period - 0xFFFFCounter mode- UpDivision - 0Repetation counter - 0ISR reads the counts accurately if the encoder signal frequency is within 100KHz, but increasing the ...

USB C Power Role swap by STUSB1600

Hi ,We are making one android accessory which required to pass through power support from accessory to android smartphone.Now we also want to communicate with smartphone by keeping our accessory in device mode.So by using STUSB1600 , Can I do data / ...

Generate velocity curve

Hi, I am a NUCLEO STM32H743ZI2 and I am trying generate one velocity curve with the register ARR. I'm using 3 stepper motors and firstly I tested the code with constant velocity but when I increment the velocity from 0 rpm to 2 rpm by 0.001 and the s...

How to obtain 32F429idisc1 the on board demo application software source code?

What is the most effective way to measure multiple pulses with interrupts?

Hello there,I'm working right now on a project, where I need to measure 6 different pulses at once. The main problem is, that I need to pulse length, not just the refresh rate. Because the traditional input capture method can only recognize a rising...

What Nucleo L476rg GPIO output mode should be used, to appropriately drive the I/O PC13 (i.e., pin connected to B1 User push-button) of another L476rg

I have need to output from a Nucleo L476rg to pin PC13 of another Nucleo L476rg, (i.e., to. the B1 USER push-button)Reason for input to this pin (which is connected to the blue USER push-button) is simply that all of the second L476rg's other pins ar...

Hello, i have to solve the task: Configure the MCU to operate with a system clock frequency of 72MHz. Make sure that the clock signal is derived from the external oscillator (HSE). Find a way to show the system clock frequency (SYSCLK) at an output pin.

This is my code so far.I solved the clock frequency of 72MHz with an excel sheet and imported the file which got created, so that is working. My HSE Speed is 8 Mhz.Now i dont get how to mirror the System Clock onto the MCO output pin.This is what i t...

How to write code that is port flexible? I have a project I want to do that the UARTs used may change by end-user config setting. So it may have communication on one or many UARTs (almost like a matrix scheme). How do I abstract the UART(s)?
