I have one NUCLEO-H7454ZI-Q, but i can't get the SDK.
How to change output frequency of timer during run time
I am using stm32L073Rz I am using Tim2 channel 3 to generate different frequenciesAs per an example ,i configure timer 2 channel 3 in TIM_OCMODE_TOGGLE modewhen i generate code using cubemx i get the desired frequency using below code snippetbut i wa...
STM32F030CCT6 pins connection
Hi,I'm very new to this STM32 MPU, I'm trying to setup a tracking device using STM32F030CCT6,GPS module and a sim.Please help me out with the setup and also please let me know the connections as I could not get enough data from the datasheet.Thanks i...
Resolved! What's the difference between PM0056 (Cortex-M3 Programming Manual) and the ARM Cortex-M3 TRM?
PM0056 seems to describe exactly the same things as the ARM TRM. Why would I read it, instead of getting the same information from its first-party source? Is there a difference that I'm overlooking?
Resolved! STM32F427 DMA transfer error -- why? (not CCM issue)
Hi,I'm getting a DMA transfer error on an STM32F427, but don't know why. I've already ruled out memory areas (ie. CCM) not accessible by DMA. Here are my registers:As you can see, S0M0AR is located in SRAM, S0PAR is a GPIO BSRR register. The transfer...
How to use the STM32F205 Canbus ID filter? it seems like it does not works as rule:
CAN Bus filter Rules: The filter mask is used to determine which bits in the identifier of the received frame are compared with the filter If a mask bit is set to a zero, the corresponding ID bit will automatically be accepted, regardless of the ...

I have Windows10 build Version 10.0.17763 Build 17763I installed DFuse v 3.0.6.The USB detection does not detect my STM32F401c-disco in DFU MODE.In the win device manager no STM device is listed.My USB cable is good, the port is good. What driver is ...
Fake Idle Line Interrupt
Hello,I use Idle Line interrupt as a timeout for UART Receive, to end up an ongoing receive process.All in all, it works good for me, but I do have a constant issue on all the STM32, like L1, L4, H7, with a "fake interrupt upon reset". That means :...
DMA behaviour on STM32F072 and STM32F745: Memory consistency
Hello,I'm currently working on a UART communication between the mentioned STM32 microcontrollers and would like to use DMA. But I'm a bit concerned about memory consistency. I already read a lot about this issue and tried to find any information, how...
