PuTTY Terminal Multiple Cursors

I'm not sure if this is the best place to ask this question, but I thought I'd try in case someone knows where I might find answers.So I'm using a Nucleo F429ZI to communicate with the PuTTY Serial Terminal on my computer. I'm regularly updating some...

Hello, I am trying to measure the time requires to transmit and receive the data over spi between two boards, I have tried DWT but DWT gives cycles according to system frequency(core) , I want the time require by the spi only.

I am using stm32f429i discovery and stm32f429i eval boards for communication. Can anyone help me?

STM32F3 - what exactly are conditions and benefits of using FLASH half cycle access?

in RM0316 rev.8. FLASH_ACR.HLFCYA is described as enabling Flash half cycle access. Narrative in chapter 4.2.2 says:If there is not any high frequency clock available in the system, Flash memory accesses canbe made on a half cycle of HCLK (AHB clock)...

C Standard Library not working on STM32H7

Hello, we switched from a STM32F7 to a STM32H7, porting the program to it. I disabled D Cache, because it wouldnt work together with the ethernet. Now we got another Problem:-Some Funtions of the STL are working, others are not. For example mmcpy or ...

ST please document in RMs, which interrupts are level/pulse triggered

It could be conveniently added to the vector table in Interrupts and Events chapter in the RMs.One reason why I am asking for this - besides the fact that this is quite a substantial information which ought to be present in documentation - is, that a...
