Hi, I am looking for simple read and write routines for I2C interface between Atmel low-end 89C55 microcontroller and 24C04 serial EEPROM.(esp. assembly code) Any help would be great . Thanks in Advance.
does anyone have any debug/signal functions for this kind of bit-level I2C code? Keil have an app note for I2C signal functions that respond to byte-registered I2C hardware blocks, but not I2C devices which the C51 controls directly, by programming the 2 pins, bit at a time, clock at a time.
Hi, look on my homepage (http://www.c51.de). I have written a complete I²C-Bus DLL with some simulations (RAM, EEPROM, RTC, I/O-Expander, ..) Mike
Michael Your I2C add-on for simulating serial eeproms worked very nicely. It clearly showed the 2-wire physical layer signalling, and nicely simulated responses to the application layer commands. It was much more than I was expecting! Thanks, Peter.
