Scpi server

This is a replacement SCPI server for redpitaya.

Building

To cross-compile scpi-server, you need arm-linux-gnueabihf-gcc and configure the linker in ~/.cargo/config:

[target.armv7-unknown-linux-gnueabihf]
linker = "arm-linux-gnueabihf-gcc"

Then add the armv7-unknown-linux-gnueabihf target to rust toolchain:

rustup target add armv7-unknown-linux-gnueabihf

And finally:

cargo build --target armv7-unknown-linux-gnueabihf --release

Testing

Start the server on your repitaya:

# cat /opt/redpitaya/fpga/fpga_0.94.bit > /dev/xdevcfg
# LD_LIBRARY_PATH=/opt/redpitaya/lib/ ./scpi-server

Then, on your computer:

$ echo 'ECO:VERSION?' | netcat rp-xxxx.local 5000
0.97-489-ef96127 (ef96127)

If you have a problem, you can display more messages:
