I am to stronge the data to the serial eeprom at93c56, and i have found the assembler code in atmel's web site.<br><br> However, i does not familar with assembler. how can i add the assembler to my C Project? Moreover, the chip have both 4 wire and 3 wire mode, what is the different betweem this two connecttion mode? pls help
Hi, I tried to implement asm-routines for this serial communication to. But after a short trial I wrote it in plain C once again because I had a lot of trouble with the asm-solution. Meanwhile I upgraded to a C166 uC and the routines are working here as well. I'm not quite shure with the three/four pin interface. But I worked with a chip which supported such modes. The difference was in three pin mode the data-pin was used bidirectional as DI and DO. I always had to toggle the port direction. As I said, I'm not shure if this is the same mode as used by at93c56!
