是硬件SPI,用的SPI2,debug时SPI2收发数据正常，退出debug、重新上电SCK脉冲乱发
DSPI_MasterSetDelay(SPI2_INSTANCE, 1, 1, 1); while(1) { DSPI_MasterTransfer(SPI1_INSTANCE, master_send1, master_receive1, NUMBER_OF_FRAMES); DSPI_MasterTransfer(SPI2_INSTANCE, master_send2, master_receive2, NUMBER_OF_FRAMES); } The CS0,SCK and Sout of SPI1 are measured with oscil...

根据SPI的时钟极性和时钟相位特性可以设置4种不同的工作模式,他们通过区分时钟的初始电平高低 和时钟的奇偶次采样来组合成四种模式详情如下所示:Mode0:CKP=0,CKE =0:当空闲态时,SCK处于低电平,数据采样是在第1个边沿,也就是SCK由低电平到高电平的跳变,所以数据采样是在上升沿(准备数据),(发送数据)数据发送是...
I2C and SPI sharing SCK/SDOby barbiani » Fri Sep 09, 2022 1:30 am Hello everybody, Does IDF currently support I2C and SPI using the same pins? I know it can be done with gpio bit-bang. Thank you.1 post • Page 1 of 1 Return to “General Discussion” Jump to Who is ...
