Signal Noise on relay module

Hello to everybody,I have a problem I can't solve with an STM32 H7 board.I wrote a little app to command a solenoid valve (24V, 200 mA). It's very simple, I have two software buttons for opening and closing it, using a relay module.Testing it, everyt...

Board with the most capacity for GPIO_EXTI (external interrupts)

HelloI am planning to start a Hardware MIDI Control Surface design that incorporates a large quantity of rotary encoders, so I am searching for a prototype / evaluation board that has the most potential for GPIO_EXTI (external / attached interrupts)....

stlink v3 work with stm32f411 mcus

Hi there.ive recently made my own circuit board which and I having trouble getting the stlink v3 to detect my f411 mcu. I've checked my oscilloscope and I can see the swd, swclk , and reset lines being driven by the programmer but I'm unable to get t...
