filterAcceptRange - Set range of CAN identifiers to pass acceptance filter

Note   filterAcceptRange will be removed in a future version. Use filterAllowAll, filterAllowOnly, or filterBlockAll instead.

Syntax

Description

filterAcceptRange(canch, rangestart, rangeend) sets the acceptance filter for standard identifier CAN messages. It allows messages within the given range on the CAN channel canch to pass. rangestart and rangeend establish the beginning and end of the acceptable range. You can use this function with Vector devices only.

Notes   You can configure message filtering only when the CAN channel is offline. CAN message filters initialize to fully open. filterReset makes the acceptance filters fully open. filterAcceptRange supports only standard (11-bit) CAN identifiers. You must set the values from rangestart through rangeend in increasing order. filterAcceptRange and filterBlockRange work together by allowing and blocking ranges of CAN messages within a single filter. You can perform both operations multiple times in sequence to custom configure the filter as desired.

Tips

When you call filterAcceptRange on an open or reset filter, it automatically blocks the entire standard CAN identifier range, allowing only the desired range to pass. Subsequent calls to filterAcceptRange open additional ranges on the filter without blocking the ranges previously allowed.

Input Arguments

canch	The CAN channel that you want to set the filter for.
rangestart	The first identifier of the range of message IDs that the filter accepts.
rangeend	The last identifier of the range of message IDs that the filter accepts.

Examples

canch = canChannel('Vector','CANCaseXL 1',1)
filterAcceptRange(canch,600,625)
filterAcceptRange(canch,705,710)
