More details about the hardware accelerator in stm32h730vb ?

stm32h730VB，Mathematical acceleration • CORDIC for trigonometric functions acceleration • FMAC: Filter mathematical accelerator​Are those mathematical accelerations fixed-point or floating-point ? 32bit or 64bit ?​

CORDIC with DMA is not woking when using LL drivers.

Hi,I am trying to use CORDIC in DMA mode in STM32G4 using LL drivers. However, the data from the input buffer is not being transferred to the CORDIC WDATA register. But the data from the CORDIC RDATA register (the initial value zero) is being transfe...

How to find out which STM32 supports full set of DSP instructions inside STM32CubeMX?

Which settings/configuration I need to use for dual boot on Nucleo F767ZI?

I am using STM32F767ZI nucleo board (2Mb of flash) with dual bank (nDBANk=0) and dual boot (nDBOOT=0) but I am not able to run a simple program that toggles LED1 using HAL functions. When I enable Dual Boot in the option bytes, the program stop to wo...

Hello i am new to stm32 thank you for your help i have an project on l4 and we want to make it on g0, do you think it is possible?

keil v5: assign member variables when creating C++ class object go wrong, after new operator all assignments are not what I set.

​after executing constructors:m_Handle and bbb both with int type are not what I write, it seem it's memory alignment problem but all related class has 32bits int type member variables.And I define g_pointer=(int*)m_Handle, the address  g_pointer sav...

STM32F411CE hardware timer in encoder mode won't increment

I'm using a STM32F411CE on a blackpill dev board with a second connected as a BMP debugger.I'm attempting to use the hardware timer quadrature encoder support and having absolutely no luck. I've followed the guidance in both the application note AN40...

Timer PWM: Get State of PWM

Hello,I am planning to use the PWM feature in the timer (PWM Generation CH1). I want to send that PWM signal to an external device and am doing preliminary testing on the code. This PWM duty cycle changes based on the press of a button. I want to ver...

RM0385 has references to nonexistent GPIOx_BRR register.

RM0385 rev.8 has two references to nonexistent GPIOx_BRR register in the GPIOx chapter, even if there's no such register in the 'F7.As changelog witnesses in v2 (under "Updated c7amba_ioport_UserSpec" :) ), there used to be a GPIOx_BRR description (p...
