Marian Buschsieweke f9aab53e16 tests/periph/uart_locate_pins: new test/utility app ... This application uses `soft_uart` to bit-bang the name of a number of configured GPIO pins via said pins at 9600 Bd. This way attaching an USB UART bridge to one pin at a time easily reveals which MCU GPIO pin a given pin on a board corresponds to. This is useful when no schematic and no silkscreen labeling is available, or when the information is misleading or outright incorrect (looking at the E180-ZG120B-TB).		2024-01-18 10:42:13 +01:00
