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...
