### ads1220/dump_ads1220
This endpoint is used to subscribe to raw ADS1220 ADC data.
Obtaining these low-level ADC updates may be useful for diagnostic
and debugging purposes. Using this endpoint may increase Klipper's
system load.
A request may look like:
`{"id": 123, "method":"ads1220/dump_ads1220",
"params": {"sensor": "load_cell", "response_template": {}}}`
and might return:
`{"id": 123,"result":{"header":["time","counts"]}}`
and might later produce asynchronous messages such as:
`{"params":{"data":[[3292.432935, 562534], [3292.4394937, 5625322]]}}`
### pause_resume/cancel
This endpoint is similar to running the "PRINT_CANCEL" G-Code command.
