More a little post-it than a post, I wanted to put somewhere the commands :<\/p>\n
Using the eeprom is as simple as these two commands :<\/p>\n
[code lang=”c”]EEPROM_READ(addr)
\nEEPROM_WRITE(addr,value)
\n[\/code]<\/p>\n
A little example (reading from the USART a value and putting it in the EEPROM address 0x00)<\/p>\n
[code]
\nwhile (!DataRdyUSART());
\nchar data = ReadUSART();
\nEEPROM_WRITE(0x00,data);
\n[\/code]<\/p>\n
Note that theses header are defined in the standard xc8 header [code lang=”c”] \/* NOTE WELL: #if _EEPROMSIZE > 0 && defined(_PLIB) #if _EEPROMSIZE > 0 && defined(_PLIB) More a little post-it than a post, I wanted to put somewhere the commands : Using the eeprom is as simple as these two commands : [code lang=”c”]EEPROM_READ(addr) EEPROM_WRITE(addr,value) [\/code] A little example (reading from the USART a value and putting it in the EEPROM address 0x00) [code] while (!DataRdyUSART()); char data = ReadUSART(); EEPROM_WRITE(0x00,data); … <\/p>\n

\nEEPROM_READ() is NOT safe to use immediately after any
\nwrite to EEPROM, as it does NOT wait for WR to clear. This is by
\ndesign, to allow minimal code size if a sequence of reads is
\ndesired. To guarantee uncorrupted writes insert
\nwhile(WR)continue;
\nbefore calling EEPROM_READ().
