There was a problem hiding this comment.
While my way of dealing with the protocol might be considered slight overkill, this should be a separate PR I think.

While I am all for input validation, I would like to have all protocol handling changes in a separate PR. |

…n values Adds validation to prevent out-of-range values from being written to hardware or stored as calibration coefficients. Changes: - pwrctl.c: Add sanity limits (65V max input, 60V max output, 20A max current) - opendps.c: Validate calibration coefficients with reasonable bounds Invalid values are rejected, maintaining the last valid state. Prevents potential hardware damage from invalid ADC readings or calibration data.

Input Validation for Safety
Adds validation to prevent out-of-range values from being written to hardware DACs.
Changes
protocol_handler.c: Validate parsed command values before processingpwrctl.c: Add bounds checking (65V max input, 60V max output, 20A max current)opendps.c: Validate calibration coefficients (current ADC gain: 0.1-100.0f)Behavior
Prevents potential hardware damage from malformed commands or invalid calibration data.
