Re: [USRP-users] UHD Converter for X310 series with unsupported data format

[Kei Nguyen via USRP-users]

s16 (int16_t) -> f32 (float) is not implemented.
https://files.ettus.com/manual/structuhd_1_1stream__args__t.html
I also checked the converters in host/lib/convert/ and couldn't find it.
Am I missing something?
Also, when I create a new converter do I have to rebuild the UHD?

Thanks.

Like I said, s16 -> fc32 is already implemented. Assuming your FPGA code
produces real samples (s16), you then select f32 as your output format.
Select appropriate values in your uhd::stream_args_t struct.

I mean s16 -> f32 not sc16 -> fc32, which is already implemented.
I looked through the document but it's not clear to me. I'm not sure about
UHD code structure. Could you explain in more details?

Sorry for any confusion.

s32 is unusual, as Jeff mentions. s16 -> f32 are already available.

Maybe start here:

https://files.ettus.com/manual/page_converters.html

Adding new formats to the host software should be easy, but adding new
formats to the FPGA is more work. Why do you want s32 OTW?

[USRP-users] UHD Converter for X310 series with unsupported data format

[Kei Nguyen via USRP-users]

Hello,

I'm very new to UHD and USRP stuff. I want to ask if it is possible to
integrate a converter with format unsupported by UHD, for example, s32 on
device (otw) and f32 on host (cpu)? Also, is there any explicit document
for how I can do this?
Sorry if my question is rather unclear because I'm really unfamiliar with
UHD yet.

Thanks,
Hai
