The VL53L5 circuit in explosive atmospheres and the ATEX standard.

We would like to use the VL53L5 to measure the fuel level in a tank. According to the ATEX standard, the measuring device with the VL53L5 will be located near an opening in the tank in Zone 0.The datasheet does not specify the optical power of the ci

Why did ST assign a pin to their official board and software when it can't even be configured in CubeMX?

Looking at the Ethernet PHY circuit of the STM32H735G-DK, the MCU and MAC are connected via the RMII interface, and a pin named "RMII_RX_ER" is connected to the MCU.However, if you configure it for RMII in CubeMX (version 6.18.1), this pin does not a
