Hi,
looking for xmc4000 peripheral driver lib, I have found information (http://www.infineonforums.com/archive/index.php/t-490.html?) that there are plans for realising such library in the first quarter of the 2015. I wonder if it is true, because I start now project on XMC4500 and I need to know if I have to prepare such library for my own? Unfortunately Dave apps does not support all ccu4 modes of operation. I need 64bit free running counter with atomic read for time stamping purposes and support for 64bit output compare for delayed event generation. So far I have found only counting and pwm apps.
Best regards,
Mariusz

Hi Mariusz,
I believe you are aware that XMC Peripheral Library (XMC Lib) is online. You may want to use CCUx LLD to build your own library since the timer concatenation is not support in the available PWM Apps.
Best regards.

Hi Sophia,
yes I am aware, I have post this question just before you have released DAVE4 with XMC lib. Besides, unfortunately, I come to the conclusion that CCU4/8 units haven't been designed to applications I have described previously.

Hi Mariusz,
I apologize that I have overlooked this post which requires moderator's approval before it becomes visible.
As for the application you required, I will check with my colleague and get back to you later.

You need to enable all the time slices for your application. As for the atomic read, you can use global start control bits (CCUCON.GSCxx) to trigger SW capture event then read the capture register values (eg.CC8yCxV.CAPTV).

The HTML format help files are available in "XMC_Peripheral_Library_v1.0.0.zip".

Thank you Sophia, I have already come to similar conclusions
http://www.infineonforums.com/threads/2847-CCU8-SW-capture
This problem is not so important. The real problem is with the compare functionality that I need to generate delayed events relative to actual time. The CCU has compare CRy registers that can't be set directly. To set CRy register user has to write to the shadow registers SCRy and wait for the shadow transfer (on period march or on one match) to copy from SCRy to CRy. This is unacceptable, because event may be located before period/one match. Moreover in concatenated mode shadow transfer in LSB doesn't trigger transfer in MSB what does not make sense
http://www.infineonforums.com/threads/2853-CCU8-shadow-transfer-and-timer-concatenation
I can't say that CCU slice support full concatenation, eg. to start concatenated timers I have to issue start separately for each slice (TCSET) or use external event that has been already reserved for capture purpose.
Furthermore timer value can't be set immediate on user request what I have discussed here
http://www.infineonforums.com/threads/2863-CCU8-Updating-timer-value-on-the-fly
All together this does not look so promising.

Mariusz

Thanks,
I originally did only download DAVE 4.0.
It contains the XMC Lib, but not the documentation.
It is worth adding it and also a link from the "Help->Help Contents" menue

I did not expect it under DAVE Apps, because the XMC Lib is aisd to work without DAVE Apps.
But Thanks for pointing to it.
You shoud think about placing the link one section level higher.

Hi,
I trying to use the XMC Lib with Dave 3, but I had no success so far. Is it even possible?
I followed the instructions in Readme.txt but when I make a build i get the following error:
Any idea what is wrong?
edit:
Ok I played a bit with the include paths and now the error is gone. But now I get a new error:
