Silicon labs for the C8051F020 mcu full-duplex SPI (4 lines) debugging some of the procedures from the device, its main device to receive data packets from the serial port 1 sent to the PC, from the serial port can be seen aides. development environment for KeilC, the need for U-EC3 emulator downloaded to mcu in order to debug. This From Another SPI_test are two related procedures, but the configuration of the two there was a great difference. if we are to achieve full- duplex, the need from the devices in that: in the main device to initiate communication will be ready before the data buffer assigned SPIDATA (Note that to send and receive buffers are one and the same). When the master device to initiate communication, the master-slave devices send data at the same time. very interesting the!:)
