This function must be called to start the tasks. Once the tasks are set up, vTaskStartScheduler is called. eventGenerator will use the queue to send data to task eventManager. In the main function the queue and two tasks are cerated.

I think it is some CMSIS related stuff but it would be great if someone could explain the reason for two separate functions and which one is best to use. In most of the examples, osThreadCreate is used to create a task whereas the freeRTOS documentation says to use xTaskCreate.
I was going through some freeRTOS examples for STM32. Also im sugesting to change tskIDLE_PRIORITY with 5 which is 'standard' priority. Esp32 tasks require minimum about 760kB and you have set only 200*. xTaskCreate( prvTask1, "Task1", 200, NULL, tskIDLE_PRIORITY, &xTask1 ) xTaskCreate( prvTask2, "Task2", 200, NULL, tskIDLE_PRIORITY, &xTask2 ) Here is the issue. For tips on defining the right stack size, see the "Debugging in FreeRTOS. Queues, mutexes, and semaphores will also allocate heap memory when created. The task stack size is defined when creating the task. Prodigy 40 points Hi Ming, Thanks for the reply.xTaskCreate(), the memory will be allocated on the heap for that particular task consisting of a stack and a task control block (TCB). Cancel Up 0 Down Cancel 0 Aaron Renny 21 days ago in reply to Ming Wei. Finally, xTaskCreate and xTaskCreateStatic are both FreeRTOS fucntions, while TaskP_construct is a DPL function which is a higher level function. Task 2 has a higher priority than Task 1 so Task 2 is the only task to ever enter the Running state. XTaskCreate( vTaskFunction, "Task 2", 240, (void*)pcTextForTask2, 1, NULL ) to xTaskCreate( vTaskFunction, "Task 2", 240, (void*)pcTextForTask2, 2, NULL ) 36 37 The scheduler always selects the highest priority task that is able to run.

After it is done, click on Open Project:Īll we need to do now is to crete loop for blinking LED. Now we go to Menu -> Project -> Settings… enter our program name and select SW4STM32 as Toolchain/IDE and click Ok:Īll we have to do here is to generate our code, Menu -> Project -> Generate Code. We also need to configure clock, we enter 72MHz as HCLK and USB speed should automaticaly be set to 48MHz: We also need to enable SWD for programming, otherwise, we will only be able to program our microcontroler once. Select New Project and fom list of microcontrollers select STM32F103C8: Now we can start CubeMX and configure everything. We can also see that the board has microcontroller’s USB connected to Micro USB connector: In the schematics we can see that the LED is connected to pin PB12:
SMT32F103 BLUE PILL SCHEMATIC PDF
In this article I will guide you through to make LED on Black Pill blink and also to send “Hello World!” through USB to terminal on your computer.įirst we need the schematic diagram to know what goes where, this is the only site where I found it, this is link directly to PDF with schematic.
