This example is supposed to work together with the SPI receiver. It uses the standard SPI pins (MISO, MOSI, SCLK, CS) to
transmit data over in a full-duplex fashion, that is, while the master puts data on the MOSI pin, the slave puts its own
data on the MISO pin.
This example uses one extra pin: GPIO_HANDSHAKE is used as a handshake pin. The slave makes this pin high as soon as it is
ready to receive/send data. This code connects this line to a GPIO interrupt which gives the rdySem semaphore. The main
ready to receive/send data. This code connects this line to a GPIO interrupt which gives the rdySem semaphore. The main
task waits for this semaphore to be given before queueing a transmission.
