Digital Discovery - digital pattern generation from file?

[Serdar]

I am interested in the digital pattern generation feature. Can it take data from an ascii test file, one byte per line and output/play it to the IO? If yes, can I specify the clock rate at which this data from the file will be played out?

Thanks.

Hi @Serdar

You could use a custom Bus and import data from file (up to 32k/channel) or use Script to generate custom pattern or parse the imported data.

Attila, thanks for the response. We want to import from a file in which every line (sample) has 6 bits of information. 32K samples is too small for us. Is there a way to handle much larger number of samples (eg. 10M samples)? This data is coming from an audio sample file so we can't create these samples with a script.

Hi @Serdar

Unfortunately it is not supported. The custom pattern is limited to 32k/channel.

Hi Attila,  do you have another product or variant of this product that has this kind of playback capability?

Hi @Serdar

I don't know when will such feature be added for Digital Discovery.
You could use a micro-controller or FPGA development board for such purpose: https://store.digilentinc.com/
