AURIX™ Forum Discussions

Hello,

regarding the ASCLIN module the question came up how to configure it to be used with devices that need SPI mode 0.

If I see it correctly only the clock polarity can be changed, but not the clock phase.

Thus typically the connected slave device would need to understand SPI mode 1 or 2.

Is there a way to change the clock phase?

(Using iLLD)

Hi!

I use the CCU6 timer in my project, as in the example "CCU6_ADC_1 for KIT_AURIX_TC397_TFT" , but instead of one ADC Group, I use eight. I assigned each one as a master, and for each one I specified "IfxEvadc_TriggerSource_0" (everything is as in the example). Also in the interrupt handler, I measure the time to see the actual sampling rate (the time it takes for the counter to reach the sampling rate value). For one Group at any sampling rate (taking into account that the period of timers T12 and T13 does not exceed 65535), the time takes 1 second (if you just run the code from the example), but if I use two Groups, the time is halved to 0.5 seconds (that is, the frequency is doubled?), if I use four Groups, then by the same analogy, the time is reduced fourfold (to 0.25 seconds) and so on. At the moment, I don't understand the documentation well, and I can't explain this behavior in any way. I need eight Groups (each with one Channel) to convert values at the same time, and I tried to implement this using CCU6. I tried to assign one Group as a master and the others as slave, but the result was only on the Channel of the Master Group.

How to make ADC Groups work synchronously correctly? I don't have a task to use only CCU6, it just seems to be the most convenient for me right now.

I am working with a custom board with an AURIX TC397X chip. At the moment, the eight analog inputs (receiving the signal I'm working with) for the ADC are divided into eight Groups.

Hi,

I used the TC275_OneEye oscilloscope code example in my project.

In the code, I use CPU0 as the oscilloscope and CPU1 to update the sampled data. The code in CPU0 is almost the same as in the code example, except that initSignals() has been cancelled.

In OneEye, I follow the PDF provided in the code sample. But it can not add signals to the oscilloscope, as shown in the following figure:

I don't know what caused it. Please help me!
