Configuring a Timer to measure high time on a GPIO

I'd like to be able to configure a channel for TIM2 (or any 32 bit timer) on an MCU. (STM32G474 in this example) to accumulate the total HIGH time over continuous wave forms. I know I can accomplish this using IC mode and do the math in an ISR by det...

RTC (LSE) Running very slow

We are using STM32G030's internal RTC with LSE. The bypass capacitors we have used as shown in the schematic is 22pf (assuming 1.5pf stray capacitance). The crystal we used has Load Capacitance is 12.5pf. This resulted in the RTC being slow, 1 min pe...

Using type C usb instead of micro usb

Goodmornig,I'm designing a board with an stm32wb microcontroller and I would like to use a type c connector for power supply (some hundreds of mA maximum) @ 5V the board and possibly to transfer data with the microcontroller. No advance type-c featur...
