Dears.

There are four slave devices in SPI MASTER. Why can only set the number of slave to 3 in APP, while the maximum display can be set to 8?Thanks.

问题应该是出在你管脚分配上面,你自己按照我下面的截图分配一下,看是否可以解决问题?我这边测试的时候,没有遇到问题。

1: Which device do you use? Could you attach your test project here.

2: If you want, you could use Chinese to describe your issue.

Hi Lingling,

通过DAVE新建了一个工程文件,主要功能是:XMC4300做主机,通过1路SPI 连接4个不同的外设,通过配置不同的片选,来达到分别控制外设,当对SPI MASTER APP 进行配置的时候,片选最大可以设置3,但是软件提示设置范围0到8,实际操作并不能设置成4-8,测试最大只能到3,不清楚这是什么原因?谢谢。

Dave版本是4.5.0, SPI MASTER APP 版本V4.3.30 ;
