How do I create a .FLM file?
HiI use stm32h750vbI want config qspi with w25q64 but i can not make .flm file for keil mdk
how I can design external flasher for any QSPI single flash connected to STM32H750VB in memory mapped mode?
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...
Resolved! Fastest way to set output pin?
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...
IWDG reset in stop mode
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...
Unable to generate complementary pwm signal with DMA.
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 ...
Change Baudrate
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?
What is the maximum GPIO to memory DMA throughput on a STM32-H743ZI clocked at 480 MHz when running 1 or 2 channels simultaneously?
I would like to attach 2 high speed A/Ds connected via parallel GPIOs and run them at 50 MHz each, or 100 MHz aggregate. One A/D is 12 bit and the other is 8 bit so I could take advantage of FIFO packing on the memory side. The capture buffer size ...
Is the US government allowed to use ST chips?
I've been wondering this for a while. Are there any restrictions on the US government or its contractors with regards to using STM32 chips in their hardware? For instance, would there be restrictions against a government contractor developing a new s...
cant read a register with SPI
Hey There,Ive got a Semtech SX1261 Board (LoRa- tranceiver) and iam trying to read its registers with my STM32L432KC (with SPI)Ive got working arduino code to read all its registers, but its giving me different results when i try the same thing with ...
