问题可能是由于时钟模式配置错误导致的。SPI时钟模式有四种,分别是模式0、模式1、模式2和模式3,其中...
Every thing i understood. But i didn't know about Clock phase and Clock polarity. As there are 4 wires(MOSI, MISO, CS and SCK). I came to know from document, there are 4 modes of operation in SPI depends on Clock phase and clock polarity. for example If the phase of the clock...
xinlangzaihou 该问题已经解决,通过将增加IDEL时间(spiMasterChannelConfig.base.mode.csInactiveDelay= 1;),在发送数据前可以看到CLK的时钟信号变为高电平。 JackLiu Level 3 应该是配置问题,查看一下SPI CLK的空闲状态是高还是低 对英飞凌产品有兴趣? 购买支持...

Solved: While testing the SPI clock modes I measured the following graphs with my logic analyzer: SPI clock mode 0: SPI clock mode 1: SPI clock mode
Software can select any of four combinations of serial clock (SCK) phase and polarity with programmable bits in the SPICR. The clock polarity (CPOL) bit selects an active-High (clock idle state is Low) or active-Low clock (clock idle state is High). Dete
I'm interested in connecting two devices to the same SPI bus which differ on the idle clock polarity (defined as CPOL). The MPC5744P i'm working on provides a clever resource to deal with this, which are the CTAR registers and the CTAS field when performing a TX write. However, I...
