ClementBreteau 1:f3f702086a30 19 * A serial port (UART) for communication with other devices using
ClementBreteau 1:f3f702086a30 20 * Half-Duplex, allowing transmit and receive on a single
ClementBreteau 1:f3f702086a30 21 * shared transmit and receive line. Only one end should be transmitting
ClementBreteau 1:f3f702086a30 22 * at a time.
ClementBreteau 1:f3f702086a30 23 *
ClementBreteau 1:f3f702086a30 24 * Both the tx and rx pin should be defined, and wired together.
ClementBreteau 1:f3f702086a30 25 * This is in addition to them being wired to the other serial
ClementBreteau 1:f3f702086a30 26 * device to allow both read and write functions to operate.
ClementBreteau 1:f3f702086a30 27 *
ClementBreteau 1:f3f702086a30 28 * Example:
ClementBreteau 1:f3f702086a30 29 * > // Send a byte to a second HalfDuplex device, and read the response
ClementBreteau 1:f3f702086a30 30 * >

ClementBreteau 1:f3f702086a30 32 * >
ClementBreteau 1:f3f702086a30 33 * > // p9 and p10 should be wired together to form "a"
ClementBreteau 1:f3f702086a30 34 * > // p28 and p27 should be wired together to form "b"
ClementBreteau 1:f3f702086a30 35 * > // p9/p10 should be wired to p28/p27 as the Half Duplex connection
ClementBreteau 1:f3f702086a30 36 * >
ClementBreteau 1:f3f702086a30 37 * > SerialHalfDuplex a(p9, p10);
ClementBreteau 1:f3f702086a30 38 * > SerialHalfDuplex b(p28, p27);
ClementBreteau 1:f3f702086a30 39 * >
ClementBreteau 1:f3f702086a30 40 * > void b_rx() { // second device response
ClementBreteau 1:f3f702086a30 41 * > b.putc(b.getc() + 4);
ClementBreteau 1:f3f702086a30 42 * > }
ClementBreteau 1:f3f702086a30 43 * >
ClementBreteau 1:f3f702086a30 44 * > int main() {
ClementBreteau 1:f3f702086a30 45 * > b.attach(&b_rx);
ClementBreteau 1:f3f702086a30 46 * > for(int c = 'A'; c < 'Z'; c++) {
ClementBreteau 1:f3f702086a30 47 * > a.putc(c);
ClementBreteau 1:f3f702086a30 48 * > printf("sent [%c]\n", c);
ClementBreteau 1:f3f702086a30 49 * > wait(0.5); // b should respond
