Has anyone developed an i2c sniffer > for Win32 I can use to help me along? > In the bttv-0.7 package there is a tool, called "detect", which uses the I2C userspace device to scan the I2C bus for attached devices. Perhaps this can be of help in order to see if your remote is I2C of gpio attached to the SAA7134. If you scan the I2C bus with this tool, you will find a tuner. And if there is a I2C based remote, this will show up in the list of I2C devices attached to the I2C bus of you SAA7134. Example: [vervoort@pc6475 tools]$ ./detect 0x40: ??? 0x76: ??? 0xc0: tuner (error: Device or resource busy) [vervoort@pc6475 tools]$ In this case I find a tuner on addres 0xC0, an SAA6752 MPEG-2 encoder on addres 0x40 and an I2C I/O expander on addres 0x76.
