21 | Generic I2C filtering protocol decoder. |
22 | ||
48eee789 UH |
23 | Takes input from the I2C protocol decoder and removes all traffic |
24 | except that from/to the specified slave address and/or direction. | |
61c2bd36 | 25 | |
48eee789 UH |
26 | It then outputs the filtered data again as OUTPUT_PROTO of type/format 'i2c' |
27 | (up the protocol decoder stack). No annotations are output. | |
61c2bd36 | 28 | |
48eee789 UH |
29 | The I2C slave address to filter out should be passed in as an option |
30 | 'address', as an integer. A specific read or write operation can be selected | |
31 | with the 'direction' option, which should be 'read', 'write', or 'both'. | |

33 | Both of these are optional; if no options are specified the entire payload | |
34 | of the I2C session will be output. | |
