Hello, Thanks for your post. From my understanding, the settings you have made is actually CPOL=0, CPHA=1. If you want to set with CPOL=0, CPHA=0,
模式1、模式2和模式3，其中模式3的时钟极性（clock polarity）为1，时钟相位（clock phase）为1。
One of the devices in SPI bus uses kLPSPI_ClockPhaseSecondEdge whereas the other device uses kLPSPI_ClockPhaseFirstEdge . I am using LPSPI_MasterTransferBlocking(LPSPI_Type *base, lpspi_transfer_t *transfer) from fsl_lpspi.c to send&receive messages. But the transfer config cannot config...
百度试题 结果1 题目SPI通信的工作时序有两种,具体由CPHA(Clock Phase,时钟相位)和CPOL(Clock Polarity,时钟极性)决定。正确错误 相关知识点: 试题来源: 解析 错误 反馈 收藏
TC3XX的SPI模式3(clock polarity = 1;clock phase=1)的CLK初始状态问题 xinlangzaihou Level 2 我按照官网提供的SPI例程,先初始化Module,然后在Channel初始化时,将SPI模式配置为3(clock polarity = 1;clock phase=1)。但是此时CLK的状态仍然为低电平,只有当发送一帧数据后,CLK状态才能够变成高电平。这样的话...
We're using SPI to communicate between two KL26 microcontrollers. The slave device is set to use DMA and master is not. Encountered problems that *seem* to be related to the clock phase. At least the problem goes away when CPHA is set to 1 in...
Solved: Use S32DS3.5 and select Example core à Lpspi_Ip_Transter_S32G274A_M7 The configuration needs to be set to CPOL=0, CPHA=0. Is the following
