I have an STM32H743. I am trying to configure a Layer 4 inverse filter on destination port . My intention is to allow all broadcast traffic except for one that has a particular destination port.

Hello everyone. I use STM32F4 to transmit CANBUS messages. When i connect Can High and Can Low lines to CAN-USB transformer i see messages coming to computer but after a short while the communication between MCU and computer stops. If i reset the MCU...

Resolved! Hi i am Roberto, For my project i need to update the firmware from USB port so i need to use internal bootloader. The MCU is contained into a close box so i can't set BOOT0 pin manually. Do you have any idea ?

My idea is that:I want to put a resistor and a capacitor on BOOT0 pin. When normal code is running and i will go to update the firmware, i will send a command to USB. When MCU will receive this command, MCU will set BOOT0 pin to high state and charge...
