Hello I created a task that is needed to be executed from ISR. previously I did for ESP32 but using the same manner, I could not do it. Based on my search, I found 2 ways which I tried but could not have my task run. first manner:Inside the ISR: Base...

Previously I wrote a program for - Nucleo-H755ZIQ in which I used SPI- UART- RTOS. After a long time, I wanna make a new stm32 project and reuse some previous function I was using correctly before. The problem is that not only those functions don't w...

Hi every body! I chose STM32H755ZI MCU mainly because it has 1MB of RAM. In my project, I need to at least store 180 KB of Data. 45000 of float samples. I use the M7 Core which accesses the AXI RAM the size of which is 512KB; on the other hand, the B...

Hi every body. I want to manage two events with general purpose timers 16 and 3. As a convention in ARM processors, as much as I know, the lower interrupt number corresponds to the higher priority. So I think I need to manage event with higher priori...

the problem is that When I define the arrays like this :float Data_Set_X[15000]; float Data_Set_Y[15000]; float Data_Set_Z[15000];I get the RAM overflow error which is: `.bss' will not fit in region `RAM' Timer-Blink-Test_CM7 C/C++ Problemwhen I init...

the code is too long to be posted here so I attach it as a file. due to dependencies between the part of the code I upload the whole code which is the most simple one. although it is long. this code works properly and the line related to task notific...

Thanks, I created a task and it works properly. scheduler works. when I wanna enable task notification the task does not work and based on RTOS DOCS I did all the required thing as far as I know do you have any hints ?

although your first reply was really helpful, please reconsider what you wrote as the second reply, nothing can be learned from it. if you would like to help please address the problems strait forward.from where I have to include files? what kind of...

Thanks for answer. I am new to this stuff. was a a bit confusing... . If I write a code like similar to the example 1 on this page:https://www.freertos.org/RTOS_Task_Notification_As_Counting_Semaphore.htmlin this line no more event is undefined. if(...

Hi , the probnlem was that I forgot to assign SPI_CS pin to the m7 Core inside the CubeMX . Thanks for your reply

STM32 H7755ZI- FREE RTOS- Task notification from ISR

STM32- Nucleo-H755ZIQ- LED blink- SPI

Problem with STM32h755, when expanding the accessed RAM area by Cortex M7 core, the program crashes.....

Specifying the Interrupt priority.

If we initialize an array would it be stored in a different partition of RAM in comparison with the condition under which we do not initialize the array ? initialized array: float Data_Set_X[15000]={0}; uninitialized: float Data_Set_X[15000];
