HelloI have tried to run a microSD on STM32L4R7ZI and run code from CubeMX 4.26.1 to access the microSD card. According to SDCard Physical Layer spec the card clock should have a rising edge to signal a valid bit clocked into the card. But STM32L4 ge...
Hello,My aim is to get data from two ADC channels in order to extrat data into a file. I want then to analyze data with Matlab.For now I achieve to see the two signals in my debugger but I can't manage to extract them from there.I am using a Nucleo F...
Hi all!I'm starting a new application concerning the driving of a small stepper motor by means of the L6480 driver, I'm also new with the ST software toolchain, so I kindly ask to be patient if some question may be obvious from some certain point of ...
while debugging with ic5000 these control got stuck up and returning to the main ...
Hello Everyone,I am using Nucleo-32 board in my project. I am programming USART to receive 10 character data and then transmit this 10 character data back. Problem that I am observing is that if accidentally 11 character it is suppose to display erro...
Hallo all,where can I find an overview on which trace block like SWV, ETM or ETB is implemented in the different STM32 MCUs?Currently I am looking for one supporting ETB for evaluation purposes.Kind regardsStephan
STM32 experts,I bought 2xNUCLEO-F042K6 for testing purposes. Reference manual says that uart speed at oversampling 16 is 3mbit/s, for oversampling 8 is 6mbit/s.Here is my working configuration. I send 100 bytes data at 3mbit/s and oversampling 16 fro...
I've been fighting a very subtle strange QSPI bug for a while now where data is occasionally spuriously clocked out unexpectedly. Without going into too much detail about that right now, my question is about interrupt priorities. I found what appears...
Hi.I am beginner in RTOS. I want to use A semaphore that release for push button. Another task use this semaphore to toggle Led.at kernel of RTOS started, the LED was toggled once. I checked when I created Semaphore, it's count is one.what Can I do?...
I've heard that floating point operations are very time consuming. However, I've seen that many STM32 include a floating point unit. I'm using a L432KC Nucleo. How does it exactly work? As far as I know, L432KC includes this unit which supports hardw...
