Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
For my example, I have 3 tasks; UserInterfaceTask.c, WorkerTask.c and ControllerTask.c. When a user pushes a button the UserInterfaceTask detects it and sends a Queue message to the ControllerTask. The ControllerTask then updates a global Mailbox w...
I would like to manage the sleep mode of the BG96 Modem with the ST X-CUBE-CELLULAR5.2 , but I did not arrive, can you please help me with ideasIAR Workbench Kit : P-L496G-CELL02 ( STM32L496 + Modem BG96 ) ST X-CUBE-CELLULAR5.2 Manage sleep and wakeu...
Most commonly used busses like I2S use a framesize of 64bit (32bit left, 32bit right)DMA uses the bus width (also 32bit)Audiodata with bit depth 8bit is almost useless anywaysSo why does HAL_SAI_Receive_DMA() return an 8bit-value? Wouldn't it be much...
Hi to everyone. I'm developing bootloader for stm32h745. My idea is to rewrite FLASH of the M4(0x81000000) core using proramm executing int M7 core. So For this first i need to stop M4, programm M4 flash and then restart it. The issue is how to stop ...
I have a task which is responsible for triggering a pin, sometimes at a short period of a few ms. I created a freeRTOS Task which has a while(1) loop polling xTaskGetTickCount() with a vTaskDelay(1). If all my tasks have the same level priority ( f...
Can anyone tell me how to activate (which function must I run) the USB if I detect a VBUS on my EXTI Interrupt.My STM32L151 is externally Powered. I activated the SELF_POWERED function in CUBEMX. I monitor the VBUS on an external Interrupt (rising ed...
The lwip stack was initialized by cube mx (no FREERTOS). I follow the chip guide lines for the hardware (like nucleo board but with transformer built into the connector). It seems that with a fast transient on the power supply of the board everythin...
I have a question regarding the logic of the USB cdc transfer. But beforehand let me show you approach up to nowThis is in a rough version my program, It will be used for feedback control. So a fixed frequency of the main loop is mandatory (as I use ...
