[Jacob Geigle] had a problem. A GPS unit and a Bluetooth-to-serial were tying up all the hardware UARTs on an AVR Arduino project. “Software serial”, I hear you say. But what if I told you [Jacob] ...

Read Flipper Zero logs via UART using an Arduino. The Flipper docs provide a way to do it with the Wi-Fi Developer Board: https://developer.flipper.net/flipperzero ...

So let’s say your using an Arduino in your project. You already have the hardware-based serial interface working with one portion of the project and need a second serial port for unrelated hardware.

// Enables or disables HW Flow Control function -- needs also to set CTS and/or RTS pins // UART_HW_FLOWCTRL_DISABLE = 0x0 disable hardware flow control // UART_HW_FLOWCTRL_RTS = 0x1 enable RX ...
