Setup HAL UART Interrupts in a Trustzone environment without CubeMX

Hi ST,I’ve run into a whole lot of issues adding interrupt-based UART to your OEMiRoT w/ Trustzone example on a NUCLEO-U385RG-Q.As you may know this example is not compatible with CubeMX, and it’s not clear which steps are needed to manually incorpor

STPM34 Measuring 240Vrms without Neutral

Hello,We are designing an EVSE for a North American 120/240-V split-phase supply. The EVSE is connected to L1 and L2, with a nominal voltage of 240 V RMS between them. Neutral is not available at the EVSE.We would like to use the STPM34 to measure th
