Description: STC89C58软件实现SPI口做主机,STC12C4052的SPI口设为从机.实现双CPU通信.由主机从SPI口发送0x55,从机SPI口接收到数据后+10=0x5f,从SPI口发送回主机.主机接收后发到串口.串口助手观察接收数据．程度通过keil c51调试并下载到ＳＴＣ晶片运行．-SPI software STC89C58 realize I make the host, STC12C4052 the SPI port is set to slave. Realize dual-CPU communication. By the host from the SPI port to send 0x55, slave SPI port to receive data+ 10 = 0x5f, I sent back from the SPI Host . host after receiving the serial port. Serial receive data assistants observed. Extent through the debug and download keil c51 to STC chip run.

Description: SPI（Serial Peripheral Interface，串行外设接口）是Motorola公司提出的一种同步串行数据传输标准，是一种高速的，全双工，同步的通信总线，在很多器件中被广泛应用。
SPI相关缩写
SS: Slave Select，选中从设备，片选。
CKPOL (Clock Polarity) = CPOL = POL = Polarity = （时钟）极性
CKPHA (Clock Phase) = CPHA = PHA = Phase = （时钟）相位
SCK = SCLK = SCL = SPI的时钟（Serial Clock）
Edge = 边沿，即时钟电平变化的时刻，即上升沿(rising edge)或者下降沿(falling edge)。
对于一个时钟周期内，有两个edge，分别称为：
Leading edge = 前一个边沿 = 第一个边沿，对于开始电压是1，那么就是1变成0的时候，对于开始电压是0，那么就是0变成1的时候；
Trailing edge = 后一个边沿 = 第二个边沿，对于开始电压是1，那么就是0变成1的时候（即在第一次1变成0之后，才可能有后面的0变成1），对于开始电压是0，那么就是1变成0的时候；(SPI (Serial Peripheral Interface, serial peripheral interface) is a synchronous serial data transmission standard put forward by Motorola company, is a high-speed, full duplex, synchronous communication bus, is widely used in many devices.
SPI related abbreviations
SS: Slave Select, selected from the device, chip select.
CKPOL (Clock, Polarity) = CPOL = POL = Polarity = (clock) polarity
CKPHA (Clock, Phase) = CPHA = PHA = Phase = (clock) phase
SCK = SCLK = SCL = SPI clock (Serial, Clock)
Edge = edge, instant clock, level change time, i.e. rising edge (rising, edge) or falling edge (falling, edge).
For a clock cycle, there are two edge, respectively:
Leading edge = front edge = first edge, for start voltage is 1, then 1 is 0, for start voltage is 0, then 0 is 1;
Trailing = edge = second after an edge edge, the start voltage is 1, it is 0 to 1 of the time (that is, after the first 1 to 0, it may be behind the 0 to 1), the start voltage is 0, it is 1 to 0 times;)
