The python3 requirements are noted in requirements.txt
The software is based on cantools https://github.com/eerimoq/cantools, it converts messages from a dbc to vss file -i (input-dbc) (input2-vspec)
最新版本的mapping工具（生成覆盖vss_dbc.json的mapping_overlay.vspec）
操作步骤（分别可以输出两个mapping_overlay.vspec)，一个basic.sh的，一个full.sh的）： Just simply to run shell script ./convert_start_basic.sh (Test basic case setups) ./convert_start_full.sh (Test full cases setups)
将生成的mapping_overlay.vspec拖动到官方dbcfeeder目录下，将初始化的vss_dbc.json规则库用mapping_overlay.vspec覆盖
- git submodule update --init
- vss-tools/vspec2json.py -e dbc -o dbc_overlay.vspec --no-uuid --json-pretty ./spec/VehicleSignalSpecification.vspec vss_dbc.json
简单解释： which will create an output with the number of messages in that dbc file/a converted mapping json file/ and the mapping.json as our final target output file
if there are new input files that need to be converted to mapping, please edit convert_start.sh by modify the .dbc or .vspec file name. That should be easy to do.
