WebDepending on CPOL parameter, SPI clock may be inverted or non-inverted. CPHA parameter is used to shift the sampling phase. If CPHA=0 the data are sampled on the leading (first) clock edge. If CPHA=1 the data are sampled on the trailing (second) clock edge, regardless of whether that clock edge is rising or falling. CPOL=0, CPHA=0 WebApr 19, 2024 · 个人总结的是 Leading 就是第一个变成初始状态的边沿。初始状态为高电平，那么 Leading 就是它的第一个上升沿；初始状态为低电平，那么 Leading 就是它的第一个下降沿。那么结合 Spi 的极性 Polarity 和相位 Phase ，即 CPOL (Clock Polarity) 和 CPHA(Clock Phase) 关联起来 ...
