I am planning to connect a LSE 32kHz crystal and a 25MHz crystal to the HSE input, but I am having a hard time identifying whether the STM will drive my crystal selection within the limits of the 100uW drive level. I have read thru the app note, but ...
Hi folks,Today I discovered a nasty little change in the clock handling of the ADC converter. It turns out that between revision Y and revision V of the STM32H7 they fixed ADC conversion problems by inserting a /2 clock divider between fADC and the A...
Hello,I'm using the STM32H750VB and want to use the LPTIM1 to wakeup for CSTOP.But i'm not able to let the LPTIM1 run.Code: SysInt_RegisterIsr(WAKEUP_PIN_IRQn, WakeUpPinInterrupt); SysInt_SetPriority(WAKEUP_PIN_IRQn, 1, 0); SysInt_EnableIsr(WAKEUP...
Hi,I am using 2 DMA transfers (DMA2) in the following configuration. The basic project is generated with cubeMX. Mostly clocking and USB parts are done in cubeMX, everything else is done "by hand".The first DMA2 transfer uses stream0 and is transferr...
When I try to change the duty cycle with DMA I notice that some values are not correct some of the time. I know that I am sinding the right values, but the PWM signal is not correct. Is this a problem with the preload registers and how can I set them...
Hello,we use STM32H7 in our new development. I was excited about the announcement of the new revision V because it promises an increase of speed from 400MHz to 480 MHz. My distributor told me that except for that, the devices were hard- and software ...
Hello,The system has a MCU STM32L151 and here the details.ESD testing + / - 15 KV contact on the box enclosure. PCB is inside and the ground frame is connected to the board and box. F/W Test: I performed ESD test in STOP mode only. The lock is alwa...
HiI use stm32h750vbI want config qspi with w25q64 but i can not make .flm file for keil mdk
I'm interested in STM32H750VB which have great performance, all peripherals with very competitive price, but I want to extended the flash memory by connecting QSPI W25Q64FV external flash, firstly I created project using CubeMX to test the functiona...
