Control parameter checking and changing method and device, driver and storage medium

The invention discloses a control parameter checking and changing method and device, a driver and a storage medium. The checking and changing method comprises the steps that an initial function code index input by a user is obtained; if the initial function code index is a first substitute function code index, matching a target parameter value mapped by the first substitute function code index; the target parameter value is a parameter value mapped by a target function code index; the target function code index refers to a code used for mapping the target parameter value; the first substitute function code index is used for replacing the target function code index to map the target parameter value; wherein the number of function code indexes in a first substitute function code index group where the first substitute function code index is located is smaller than the number of function code indexes in a target function code index group where the target function code index is located; according to the technical
