Hi... I have a device with connected keypad to it via i2c protocol. it's a specific device and i don't have any info about what data exchange format they use. Have anyone tried to monitor an i2c bus with 8051 ? I need ideas or sources in C to paralell connect to the bus and monitor what kind of data is passing throw... Thank's
Some Tektronix 'scopes & logic analysers also support I2C: http://www.tektronix.co.jp/Products/Measurement_Prod/LA/I2C_SupUsers_Manual.pdf http://www.tek.com/Measurement/logic_analyzers/bus_support/tektronix_microsupports111003.pdf
