<d1b2> <fredzo_72653> Hi @azonenberg , here is a tiny PR needed to fix UART communication for the NanoVNA Driver I'm working on : https://github.com/ngscopeclient/xptools/pull/33
<d1b2> <azonenberg> Ok will have a look shortly

<dingwat> is there a baked-in limit on acquisition length when using thunderscope or RAM dependent? Referencing the TS crowdsupply page which says 1Gpts..

<azonenberg> dingwat: The maximum waveform side scopehal supports for analog waveforms is 2^30 samples, which results in a 2^32 byte memory buffer of float32
<azonenberg> Vulkan doesn't let you allocate >4GB of memory in a single call
<azonenberg> (the maximum digital waveform size is thus 4G points or 2^32 samples since we store them as int8)
<dingwat> azonenberg: gotcha
<azonenberg> There is a long term open wishlist item to figure out how to make a single waveform span multiple non-contiguous memory blocks
<azonenberg> nobody is actively working on it, it's architecturally difficult
<d1b2> <david.rysk> apparently that's implementation dependent and provided in VkPhysicalDeviceMaintenance3Properties::maxMemoryAllocationSize
<azonenberg> the limit can be smaller but iirc 4GB is a technological limit
<azonenberg> it uses a 32 bit size somewhere
<azonenberg> and every implementation i've seen or tested on is actually 4GB
<azonenberg> (now you may be limited to less by available free memory, but if the memory exists every implementation i've looked at will let yo uallocate it)
