How Do You Choose a Suitable Timer for Periodic Tasks on STM32?

When developing firmware for an STM32 microcontroller, there are several ways to schedule periodic tasks, including hardware timers, SysTick and software timers.I’m interested in how you decide which approach is most suitable for a particular applica

VL53L1CB behind 0.7 mm cover glass – reliable 2–3 m person detection?

Hello,I am designing a wall-mounted touchscreen panel using a VL53L1CB for wake-up and person/presence detection at approximately 2–3 metres. High absolute distance accuracy is not required, but detection must be reliable without frequent false trigg

What Is the Best Way to Handle I2C Communication Errors on STM32?

When using I2C peripherals with an STM32, occasional NACKs or communication timeouts can be difficult to diagnose.How do you usually approach debugging these issues? Do you start by checking the bus signals with a logic analyser, reviewing the timing

Does STM32H533 support hardware-accelerated SHA-3?

Hello ST Support,I am using the NUCLEO-H533RE board and would like to clarify whether the STM32H533 supports hardware-accelerated SHA-3, particularly SHA3-256.I noticed an inconsistency in the documentation:The product page and datasheet feature summ

STM32_Programmer_CLI.exe v2.23.0 seems to run slower than v2.22.0 when called from an executable.

ProblemSTM32_Programmer_CLI.exe -c port=SWD sn=<sn> and -l stlink-only each take ~30 seconds (sometimes much more) under v2.23.0 when launched programmatically by another application (CreateProcess, stdio redirected to pipes, no console window)

AES-128-CTR using SAES through MCUboot is slower than software on STM32H533 — is this expected?

Hello,I am evaluating cryptographic performance for a secure boot using a NUCLEO-H533RE board and the OEMiRoT example from STM32CubeH5.I compared two AES-128-CTR implementations:Software: mbedtls_aes_crypt_ctr(). Hardware-backed: bootutil_aes_ctr_enc
