This is a decoder for DSView (itself a fork of sigrok) that decodes hwfly-nx SPI communication between the MCU (GD32F350CBT6) and the FPGA (Gowin GW1N-1S-QFN32).
Copy the entire hwfly-nx to the decoders subdirectory within DSView install.
In decode tab, search for hwfly-nx. The hwfly-nx SPI should show up:
To configure, you need two important things:
- All the four pins (
CLK,MISO,MOSI,CS#) - Enable
Frame Decoder
Then, in Protocol List Viewer you can adjust the annotations displayed. I like
just the hwfly ones:
And with that, you're done:
