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...
I have an interrupt which I'm trying to streamline (for an STM32F031K6). I am using some commands like GPIOA->BSRR |= (1<<4);and i was surprised to see how much there is in this command in the disassembly. Is there any faster way of implementing thi...
Hello everyone, I have currently two issues with the STM32F411CC STOP mode, it could be great to have some support.I want to wake up each 1sec by an RTC interrupt. Here is my sequence to enter STOP mode:Clear RTC_WUTF flagClear PWR_WU flagEnable wake...
I'm trying to program stm32h750vb to run ws2812b RGB LED. My RGB LED is connected to TIM1CH2N. I'm unable to generate desired PWM signal with my DMA settings. I have tested PWM signal without DMA it is working fine. So, as per my knowledge my timer ...
I use the STM32F7 and I want to change the baud rate of the USART6 from 115200 to 921600 during runtime, how can I do that?
