Hi all,
I'm still working on Digilent Digital Discovery device but I've some doubt and
maybe someone can point me how to do it because I wasn't able to found it.
I need to change the samples rates list (SR_CONF_SAMPLERATE) and limit samples
list (SR_CONF_LIMIT_SAMPLES) based on number of channel enable/disabled.
This is necessary due the sampling rate and limit samples in this device
depends on number of channels configured/used.
- 32 channels enabled can capture up to 200MHz and 64M samples
- 16 channels enabled can capture up to 400MHz and 128M samples
- 8 channels enabled can capture up to 800MHz and 256M samples
One solution could do the inverse and disable the channels based on sample
rate. The device has 32 channels.
- Sample rate 800Mhz disable channel 8-31
- Sample rate 400Mhz disable channel 16-31
The problem with this solution is that I force always to capture 32 channels
and limit to 64M for other configurations and is less flexible.
Other solutions are welcome :D
