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;) Platform: |
