I designed such a I2C monitor because I needed this to debug our quite big radio systems. The interface does master / slave and monitoring functions but with some limitations: -The maximal message size for master / slave messages is 11 data bytes. This is due to the limited ramspace in the 87C654 controller that is in the interface. -The monitor monitors the bus without halting the bus (not like the simple I2C-monitor from Philips) - It works without problems with standard bitrates up to 100kHz. If there are problems (to many databytes) so that they can not be transferred to the PC there is a flag in the data stream showing that the buffer is full and that there could be missing data bytes after this message. Features: - Interface with standard RS232 connection to a PC (286/10 or higher) baudrate: 57600 - Works with PCF8584 from Philips - Supports master / slave / monitor functions - DOS-Software with disk-logging possibility. -telegrams can be defined to keys on PC-keyboard (master messages) -slave telegrams can be defined so that the interface reacts like a real slave -telegram definition can be saved in a config file As there is no manual available until now this is all I can say about it. The interface works quite well and is in heavy use for system and software debugging purposes.
