Hi all,

I am using PCWHD Version 4.073

I want to save a 16 bit address in the eeprom of a 18F2520. I understand write_eeprom(address, value) will write an 8 bit value at the address. How do I specify the upper 8 bit of the 16 bit field and then the lower 8 bits?

I have:

int16 start_addr = 0000;
int16 end_addr = 16384;
int16 address;

write_eeprom(0x00,address);

See my post in this thread. It has routines to save a word to eeprom.
This example is for external eeprom, but you can change it to use
internal eeprom by removing the word "ext_" from the function names.
