B-G431B-ESC1 20vdc Max?
Oddly the on board NFETS are rated 60v, why only 20v input? Can we safely go to +48vdc, if not why? Our motor driven FW the voltage does not go above Vbus.Is FOC space vector 7 phase or 5 phase switched? Thanks

Resolved! How to enable GPIO inputs for INTERRUPT MODE ?
The H745 Datasheet says General-purpose input/outputs : Up to 168 I/O ports with interrupt capabilityYet, every pin I select as GPIO (ex. PORTC.13 (PIN E3)), only lists INPUT or OUPUT options, but no Interrupt mode.If I bypass the Stm32CubeIde 1.3.1'...
Stm32h7 vddldo on non bga packages
Hello, I was looking for an stm32h7 part where I could provide voltage to the internal ldo from a vddldo pin to achieve lower power consumption using an external smps. I'm looking at the h743 lineup but cannot find any package with such exposed pin e...
Resolved! I am usinng STM32H7 nucleo board. I want to generate 20KHz pwm wave. How can I control the resolution (that is a value from 0-10000 that corresponds to 0-100%)?
So I adjusted the ARR and Prescalar values to adjust the pwm frequency(20KHz). Timer Clock is 200MHzI want to change the resolution in the run time with a function. How can I change it?Changing the ARR value will change the resolution?Thanks in adva...
STM32H7, ADC1 Multi Channel Mode + Interrupt Mode (Not DMA, not polling mode) Possible?
I want to use ADC1 16 channels to read different analog values. So whenever there is a data in the channel then I want to read the 16 channel data in Interrupt mode. I dont want to use DMA Interrupt mode and Poll Conversion mode. Is it possible to do...
QUADSPI timings to read, write, erase flash IC
Hello,I've a MT25QL128 IC interfaced with STM32F767 controller on QUADSPI. there is external crystal of 8MHz. I want to check timings req for read, write and erase the flash IC, so that I can write some data into flash. I've referred application note...
What`s the difference between Transmit_IT function and Transmit function?
MCU:STM32F0discoveryTools:STM32CubeMX5.6.1+Keil5.3OS: Windows 10proQuestion:When I use the PLC system`s interrupt, always the interrupt just trigger once in the first scan time.But in the MCU system, I find that the interrupt can be triggered by the ...
System Clocks for both cores are not correctly set (NUCLEO-H755ZI-Q board)
Hi guys, I recently posted similar question but now I have some actual measurements.I have measured the frequency of the clock signal comming from st link to microcontroller which was 8 MHz (correct). Then I did setup of prescalers, configure system ...
Resolved! Overcoming SPI speed limitation on H743- inspiration needed
I'm setting the SPI input clock for the port I'm using at 50MHz to allow SPI speeds up to 25MHz for use with an SD card under SPI. However, this gives a minimum speed of 50MHz/256 = 195KHz and this is too fast for initialising some SD cards. I need t...
Resolved! STM32F407 discovery board stops responding. "handle_vCont_c, Failed continue thread"
