Embedded Coder for C2000
显示 更早的评论
I've built a very simple model in which a counter is written to DAC-A on the F28379D LaunchPad. I expect to see a ramp at the appropriate pin on the board but there's nothing. I simple C program works correctly. Has anyone tried this?
My suspicion is that the DAC is not being enabled because when I inspect the generated code I don't see evidence of the DACOUTEN register being written to.
Thanks for any suggestions.
Regards,
Richard

Hi Richard,
Attached is the model which i found to be working for DAC-A. The model is created in 2018b version of MATLAB.
I found it working in both interrupt and periodic step time scenario. To get a view of ramp signal I found we need to work with high sample rate else we may not be able to make out the Ramp signal generated. You can either enable periodic/interrupt based approach to test the DAC block. Comment the other implementation which is not used in the model.
The perodic step time is set to 1ms which could give a good ramp signal. The interrupt runs still tight in usec scale. Be sure to tap the correct pin the launchpad for DAC output.
Hope this helps.

您好
如果我的计算机无法连接到Internet，是否可以安装C2000硬件支持包？

Yes, along with 'install' option for the support package, we also provide 'download' option.
That should help you to download the package and use it for offline install.
