Post by thread:internal data eeprom in PIC16F84

Hi, I have two questions about the data eeprom in the PIC16F84 1. How do I define bytes in the eeprom in the code (so they get added into the HEX file) 2. Is there any litmits how often the eeprom can be read, I want to read about 15000 bytes / second from it (read only, I plan to put strings into it for video generation) / Rickard GunŽe

The answer to you question is : Place your data at 0x2100. the way you would do it if it where in Code-memory. (EEPROM memory is 8 bit's wide) > 2.
