how to interface eeprom with pic controller 16/18f...by using i2c....i read the pdf file for i2c ... i dont know how to initial the i2c....how master send the correct address to slave...how to find that address..
i understand i2c what means ,start condition=sda is high to low with scl is high...
hi every one.....i suppose to give input voltage sample in high pass filter what will be the output..and i need to write program in ccs compiler or C.....any one help me......
hi every one, i give input through switch if its high means display 1 on lcd if its low means display 0 on lcd.... i done the program it execute correctly....but in Proteus the lcd display show nothing....but i connect in led it work correctly...i think i do some mistake in my program pls any...
