本例展示了如何實現2個SPI之間的在全雙工（full-duplex）模式下通信，通過NSS軟件管理，實現了由主向從，接著又從向主發送數據。 在本例程中，設置SPI1和SPI2為8bit數據幀，9Mbit/s傳輸速率。 在第一階段，由主SPI1把SPI1_Buffer_Tx發送到SPI2，由從SPI2把SPI2_Buffer_Tx發送到SPI1。傳輸完成后，通過比較判斷傳輸是否正確。 由于NSS管腳由軟件管理，因此，可以在不改變硬件配置的情況下使SPI1由主變從，而SPI2由從變主。在第二階段，由從SPI1把SPI1_Buffer_Tx發送到SPI2，由主SPI2把SPI2_Buffer_Tx發送到SPI1。傳輸完成后，通過比較判斷傳輸是否正確。 在STM3210B-LK1上，如果以上4個傳輸都正確，則亮起LED1（LD4），否則亮起LED2（LD3）。

The recent developments in full duplex (FD) commu- nication promise doubling the capacity of cellular networks using self interference cancellation (SIC) techniques. FD small cells with device-to-device (D2D) communication links could achieve the expected capacity of the future cellular networks (5G). In this work, we consider joint scheduling and dynamic power algorithm (DPA) for a single cell FD small cell network with D2D links (D2DLs). We formulate the optimal user selection and power control as a non-linear programming (NLP) optimization problem to get the optimal user scheduling and transmission power in a given TTI. Our numerical results show that using DPA gives better overall throughput performance than full power transmission algorithm (FPA). Also, simultaneous transmissions (combination of uplink (UL), downlink (DL), and D2D occur 80% of the time thereby increasing the spectral efficiency and network capacity

The LPC1700 Ethernet block contains a full featured 10 Mbps or 100 Mbps Ethernet MAC (Media Access Controller) designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control frames, hardware acceleration for transmit retry, receive packet filtering and wake-up on LAN activity. Automatic frame transmission and reception with Scatter-Gather DMA off-loads many operations from the CPU.
