ADP3450 Linux mode memory depth

[Andrew Zonenberg]

Hi,

 

Looking at the return values from FDwfAnalogInBufferSizeInfo(), I get 32M points on my PC via USB, but only 32K points if I'm running on the device itself in Linux mode. Why is this? Is there any way to get deeper memory in Linux mode?

 

Also, I tried updating to the latest released WaveForms version for ADP3450 but got linker errors about missing symbols. These were resolved by installing the armhf version of the Adept runtime labeled "Raspberry Pi", as there wasn't one labeled specifically for the AD Pro. Was this the correct package to use?

 

EDIT: It appears that when in Linux mode I get 32K point max memory depth even on the PC via USB, and I only get the full memory depth if I'm using Standard mode.

Hi @Andrew Zonenberg

Aha, so the limited depth is because that RAM is used by packet buffer when not running Linux. Makes sense.
