EXTI11 with SPI1 on STM32U575
I am using the gpio interrupt (EXTI) and trying to tie with SPP1. Only EXTI4_TRG and EXTI9_TRG are defined in stm32u5xx_hal_spi_ex.h for group1. Is that possible to define EXTI11_TRG in the group1?

Resolved! Error Detection for SPI DMA Master->Slave
Hello,I have an STM32F373 and setup a master uC and slave uC to communicate over SPI with DMA enabled. I send a fixed packet size of 10bytes and have set the DMA size to 20bytes in case I need a double buffer for my solution. I enabled a SS/CS out...
Best way for 2 STM32 MCUs to communicate
Hello,I am considering using 2 STM32F373 in my project. One uC will be for a control panel, and the second uC will accept commands to produce DAC and PWM output. What is the best way to have them exchange data? Should I use SPI? I see i2c is not ...
Resolved! Facing an issue with power on reset
Hi, I was facing one issue..while running firmware in my device (stm32f4)in the middle suddenly controller got restarted, when I checked that RCC reset status register and I got to know that power on reset ,but I didn't restart my device only , May I...
Does SDRAM freq 100MHz mean 10ns each clock or 10high and 10low = 20ns
Hi everyone, I am a bit confused about this.In STM32CubeMX tool, I configured SDRAM 100MHz, the tool GUI shows result 100MHz as well, then I generate code then test.I check SD clock pin, it is 10ns on each single clock, no matter the clock is high or...
Resolved! stm32h7 uart i2c GPIO_InitStruct.Pull = GPIO_PULLDOWN;
para aplicar i2c alternate function open-drain GPIO_InitStruct.Pull = GPIO_PULLDOWN o should be GPIO_PULLUP (what diferencetween both) and uart alternate function push-pull should be pull-up or pull-down what diferencetween both?
