Designed hardware for a Harness Detection System — flags wiring faults via LED indicators across hundreds of connections.
4 PCBs in KiCad: schematic capture→layout→3D verification. First hardware project, steep learning curve on power design and ESD protection.

Stop decoding STM32 status registers bit by bit. This small C function prints only the set flags by name, using a char pointer array indexed by bit position. Example output: TC TXE. Handy for debugging USART and other peripherals. #STM32

@fuyu_kasumii Is this any attention seeking post only ?

Anybody interested to learn Embedded C ?

STM32G431CBU6 has no onboard USB-UART bridge like a Nucleo. SWD flashes fine, but UART had nowhere to go.
Fix: swapped the wire for an HC-05 Bluetooth module. Same UART code, zero changes.
UART is a protocol, not a wire.
