Hello all,I have an application in which I want to control four BLDC motors independently using the FOC. I want to use a STM32G484 for this. The question now is how I can distribute the interrups so cleverly that I can control all motors with 16kHz w...

Hello all,at the moment I use the HAL function HAL_UARTEx_ReceiveToIdle_DMA to receive the data from the UART. This works very well but I have a timing problem because I want to send and receive a lot of bytes. To speed this up I want to use the LL f...

I am trying to implement a cdc device and would also like to use the FreeRTOS. For code generation I use CubeMX. To keep the interrupt of the receives as short as possible I want to send the answer to the host using a task. But after a few seconds my...

Hey @Zied b. thank you for your answer. For a first try I can use two Nucleo boards but later I want to design my own board and use only one MCU if possible. Here, as I said, I'm not sure how to get the timings right so that all four motors can be co...

Do you have an example of a good USB library I tried tinyusb but it doesnt work well

@mohamed.ayed thank you for your answer. Since my whole project is based on freeRTOS I don't want to change the operating system. Can the procedure be applied to freeRTOS ?

Thanks for your answers!I tried to start the receive in the transmit complete callback but this does not improve the behavior.

Is there a simple example how to combine USB CDC device and FreeRTOS ?
