360nosc0pe Siglent SDS 1x0xX-E FPGA bitstreams

This repo contains a LiteX project for an open source bitstream targetting the Siglent SDS 1x0xX-E series oscilloscopes.

Supported machines:

• Siglent SDS1104X-E or SDS1204X-E (exact same hardware)

Not yet supported (but likely easy to port):

• Siglent SDS1202X-E

[> Prerequisites

• Python3, Vivado WebPACK
• Either a Vivado-compatible JTAG cable (native or XVCD), or OpenOCD.

[> Installing LiteX

$ wget https://raw.githubusercontent.com/enjoy-digital/litex/master/litex_setup.py
$ chmod +x litex_setup.py
$ sudo ./litex_setup.py init install

[> Prepare the target

Follow the instructions here to prepare for JTAG boot mode.

[> Build and Load the bitstream

$ ./sds1104xe.py --scope-ip=192.168.1.50 --build --load

Instead of --load (which uses Vivado's hardware manager), configuration with OpenOCD is also possible:

$ openocd -f interface.cfg -f target/zynq_7000.cfg  -c "init" -c "zynqpl_program zynq_pl.bs" -c "pld load 0 sds1104xe.bit" -c "exit"

Due to a bug, it may be necessary to re-plug the ethernet cable after the first configuration.

[> Open LiteX server

$ litex_server.py --udp --udp-ip 192.168.1.50

[> Configure scope hardware and capture samples

Command used to capture a 115.2kbps UART:

$ ./test_adc.py --adc-channels=0 --adc-samples=1000000 --adc-downsampling=256 --afe-range=5.0 --afe-center --plot --dump=dump.csv

Command used to capture 12MHz clk on channel 0 and 6 MHz clk on channel 1:

./test_adc.py --adc-channels=01 --adc-samples=10000 --adc-downsampling=0 --afe-range=5.0 --afe-center --plot --dump=dump.csv

Command used to capture 12MHz clk on channel 0 and push waveforms to GLScopeClient:

./test_scpi.py --control-only
./test_adc.py --adc-channels=0 --adc-samples=16384 --adc-downsampling=0 --afe-range=5.0 --afe-center --glscopeclient
./glscopeclient --debug myscope:aklabs:lan:127.0.0.1

Use ./test_adc.py --help to get more information about the command line parameters.

Note: Requires export LC_NUMERIC=en_US.utf-8 with GLScopeClient.
