Hello,I am looking for help. I am using stm32L0. The problem is as follows:ST goes in stop mode for example 5 seconds. After 2 second some interrupt wakes the ST. Then I want go in stop mode for the remaining time which in this case is 3 seconds. Is ...

Hi,I'm using STM32H745 and CM4 core runs with RTOS. I am not able to create the second task because xtaskcreate() does not return pdPASS. It seems like it can't allocate enough memory. I tried to create 2 tasks with stack depth equal to 1024. If I re...

Hi,I'm trying to create multicore communication. I want to call interrupt in the second core. Firstly I thought that I can somehow make hardware semaphore release interrupt in the second core. But then I found something better in the CubeIDE:It looks...

Here is where I found this information and even you have posted this answer:https://community.st.com/s/question/0D50X00009Xke0LSAR/stm32l0-getting-rtc-wakeup-counterI will try do some tests and figure it out with your advices.

I forgot to mention that I'm curently using RTC for slepping defined time. The problem is that I found information that there is no possibily to read slepping timer after wakeup. Correct me if it's false. LPTIM seems fine. I don't need high precision...

Complexity at an absolute minimum is different for different user  If you are not intrested in RTOS you will have to use LWIP raw API. It's event-driven api, so you have to implement callback for events. I'm not enough familiar with this solution to...

Hi,In my opinion you should start from understanding the tcp/udp protocols. You have to choose which protocol you want to use and it depends on what you want to achieve. You should also know what are the differences between client/server. For IoT I t...

It can't be. It is common used technique to keep your code clean when you have to start a lot of tasks. I debug more deeply and I realized that I'm going out of the defined total heap sized as you said. I didn't expect this behavior because on the nu...
