    Recommend me PIC16 series simulator

    PIC Simulators dear; oshonsoft is the best simulator ever -from my point of view- so don't disturb yourself by searching for another simulator, just take into consideration the speed difference between actual micro controller and simulator

    Question about Atmel controller

    1. yes you can interface EEPROM serial or paraller, i am suggesting serial one 24C512 .... 2. no way as max code memory for 8951 is 4k. and for 8952 is 8k. for 8953 12K. for 8955 20K. that is it. so you have to save that lookup table in external eeprom then read it in your code block by block ..
