SPI - Clock & Chip select timing configuration problem

Riyasma07 — Mon, 18 Mar 2024 04:51:55 GMT

In SPI configurator, when I try to change the timing values for Clk2Cs, Cs2Clk & Cs2Cs from 0.000001 sec to 0.00001 sec, I'm facing an error.

But when I hover over the timing fields, it shows the timing can be set in the range of 100ns to 0.0001 sec.

Hi @Riyasma07

Sorry for the late response, due to workload my response was delayed.

Which RTD version are you using? Also, please provide your clock configuration.

B.R.

Hi @VaneB ,

I'm using RTD Version 3.0.0

The clock configuration is

and I'm using SPI0

Hi @Riyasma07

Sorry for the delay.

I had verified this situation and the cause of the problem looks to be related to S32DS and not for a wrong configuration. The error should not cause any problem with your code.

Hi @VaneB, Seems like it is causing problem with code. I've set the timing as 0.00003 sec and checked, there is no response from the slave.

Hi @Riyasma07

Are you using an external device or is it connected to other SPI modules of the S32K3? Are you using the example code?

Hi @VaneB ,

Yes, we are using an external device and not using example project.

Hi @Riyasma07

Could you share an image of the signals coming out from the S32K3?

Hi @VaneB,

Hi @Riyasma07

The signs seem correct, but to make sure the problem is not caused by S32K3, please try testing the SPI example with the settings you require.
