How to use PicoSDR within CorteXlab
- Unordered List Item
## Bitstream
You can either provide your own PicoSDR bitstream or use the one we provide by default.
If you want to use your own bitstream, you have to specify it in your scenario file and add the bitstream file in your experimentation folder. For 2×2 Picos you can specify the bitstreamA, and for 4×4 picos you can specify both bitstreamA and bitstreamB. For example if you have the bitstream file custom.bit
at the root of your experimentation folder, your scenario file will look like this :
node31: entry benchmark_rx.py bitstreamA custom.bit
If you do not specify any bitstream using a PicoSDR node, it will use our default bitstream wich is provided by Nutaq as an example. The bistream is named Radio420_GigE_6_6_0_sx315.bit
.
If you want to use this bitstream there 3 custom register to set. Register 4 can be set to :
- 0 → async
- 1 → MIMO 2×2
- 2 → MIMO 4×4
Register 3 can be set to :
- 0 → Rx disabled
- 1 → Rx enabled
The register 3 must be set to 0 during initialization.
This bitstream have several internal path which can be selected using custom register 1. In our case we want a passthrough so we need to set the register 1 with the value 6.
