Setting SPI1 to the highest clock frequency

Hello, I just wanted to ask what's the best way to set the SPI and system clock in STM32L496 to have at least 40MHz frequency for the SPI1. Thank you in advance

How can you know that an update event on TIM5 (for example) is actually an overflow?

I set up tim5 in compare mode to get an interrupt at a specific tick, but I am also interested in the overflows. I get an update interrupt very early after starting the timer, so it is definitely not an overflow. Is there some register I should read ...

SPI_Transmit get stuck at HardFault_Handler @ stm32f4xx_it.c

I'm trying to create my own library,When I use HAL_SPI_Transmit(), it gets stuck atvoid HardFault_Handler(void) @stm32f4xx_it.cI use SPI at my own library/function, not in the main function.I also check SPI_Transmit before calling my own function, it...

STM32F469I-DISCO standby mode RTC wake up immediately issue.

Posted on February 12, 2018 at 07:12I used STM32F469I-DISCO and STM32F429I-DISCO to testing Standby mode function by PWR example(Attach). Standby mode function is no problem on STM32F429I-DISCO.  But in STM32F469I-DISCO , used RTC wake up form stand...

Latest STM32CubeIDE does NOT generate Periph Clock Init code in SystemClock_Config.

Older CubeIDE generated following SystemClock_Config.void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInit = {0};   /** Initializes the R...

i want to know about the status of its production. it seems that ST do not produce the stm32 microcontrollers. if this is true so what we should do? should we switch to another microcontrollers from other competitors?

Hello, I am using STM32L4R9ZIJX STWIN board. I was able to implement a neural network and generate code. Now I want it to stream live data and make predictions based on the network. How can I set up the peripherals to do that??
