A full-duplex tiny AVR software UART

UARTs for AVR MCUs by Nerd Ralph, he writes: I’ve written a few software UARTs for AVR MCUs. All of them have bit-banged the output, using cycle-counted assembler busy loops to time the output of each bit. The code requires interrupts to be disabled to ensure accurate timing between...
