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 ...
Hi all.I have a hardware with STM32F469, running FreeRTOS and USB stack as configured from CubeMX.I have the following problem. I have a preproduction stock of this hardware and 2 USB sticks.Let's consider only 2 of the above boards (let them be A an...
I have a hardware timer using its updateEvent interrupt to increment a ms_passed variable every 1 ms. I have a freeRTOS task reading ms_passed ( via TaskNotification ) in a while(1) loop to toggle a pin at a given time interval/tempo based on a vari...
I'm working on a custom board with an STM32F072RB as microcontroller. I'm testing the firmware update via USB and I found that as soon as I jump to the internal bootloader (address 0x1FFFC800) the CPU goes down. Looking at the enables I found that t...
Hi,On the ST site local voice recognition with models from sensory is beinig advertised.I would like to prototype adding voice recognition with our product. I've created models at sensory and have an audiostream from a mems microphone on the STM32H7....
