SPI timing problem
Posted by蝙蝠侠230845 points 6 repliesHi
I have problem about SPI timing on DA14683-00A9DEVKT-P, please refer to pic of appendix, i use SPI function to write command to other chip and it works, but the timing between CS falling and first SCLK are too long, please tell me how to shorten this period.
谢谢~~

Hi ,
I almost follow theSPI Adapter Concept教程和重写代码，SPI写入/读取功能运行良好，但CS时序仍然太长，我们没有逻辑分析仪，但我认为示波器的效果几乎是相同的。我在我的代码中删除了不必要的printf函数，还有其他可能导致这种现象的因素吗？DMA？FIFO？其他任务影响？
thank~~~

Hi There,
As mentioned in your previous forum thread, please try to follow theSPI Adapter Concept导师ial. As 6yoiu can see in Fig. 19 SPI Write Transaction Captured using a Logic Analyzer, there isn’t any timing issue with the CS in a SPI write transaction. It would be very helpful to use a logic analyzer tool to probe the SPI lines instead of using an oscilloscope.
谢谢, PM_Dialog
