Hello,I am using the LSM6DSOX IMU to detect a double tap. The IMU is connected to SPI1 of a STM32U5 and the INT1 pin is connected to a GPIO (PB2) of the STM32U5 configured as external interrupt.Sometimes the double tap detection works correctly but s...

Hello,I am trying to update some code to use UART with DMA for receiving instead of the polling method.I want the implementation to work for messages of unknown length so I use the HAL_UARTEx_ReceiveToIdle_DMA function.I know that the maximum message...

Hello,I have a STM32L4 and I need it:To be able to communicate with a laptop via USB (PC = Host, L4 = Device)To be able to communicate with a custom made USB device which only support being a USB Device (L4 = Host, Custom device = Device)I managed to...

I would like to store two keys in the KMS as dynamic objects to use them in my UserApp project: One public ECDSA key One private ECDSA key For the public key, I have as example the SBSFU_ECDSA_1_Verify key so this should be fine. However, I don't kno...

Hi,I am using the the SecureBoot on a STM32L4 with the KMS, I have some questions related to the protections:As I use the KMS, I read in the UM2262: "With KMS middleware integration, SBSFU keys are no more stored in a section under PCROP protection b...

Hi @Federica Bossi, thanks for the reply. My code actually works well and I was able to setup the tap detection as I need it to be. However, my problem is that for a reason that I cannot understand, when I start writing on the SD card, the IMU stops ...

Hi,I managed to solve my problem by using the DMA in circular mode.By doing that, the DMA transfer is not stopped when entering in the HAL_UART_IRQHandler(...)So if I received 5 bytes and enter in the HAL_UARTEx_RxEventCallback(...) with Size=1, I wi...

@KnarfB Thank you for replying, I am using the STM32L486RG.

Yes I saw the example but I was wondering how the data was generated. I think the required information can be found using openssl rsa -in <my_key.key> -noout -textbut if you can check with your colleague that would be very much appreciated.

LSM6DSV16X double tap interrupt stops triggering

UART + DMA and IDLE line interrupt with HAL layer does not work as expected

How can a L4 be at the same time a USB host and a USB device ?

How can I store a private ECDSA key in the KMS as a dynamic object ?
