READ EepromCounter, temp
To make the program count the number of consecutive resets, simply add 1 to the value
of
temp and write it back to the EEPROM byte at the EepromCounter address. Next
time the program starts, the value the
READ command fetches will be higher by 1.
temp = temp + 1
WRITE EepromCounter, temp
The program can then make decisions based on the value of the temp variable. To
simplify things, the next example program subtracts 1 from
temp before analyzing it with
the
IF...THEN statement. Subtracting 1 from temp is not necessary, it just makes the
Your Turn section a little easier to follow.
temp = temp - 1
IF temp = 0 THEN
DEBUG "Since download, you have", CR,
"pressed Reset ", DEC temp,
" times.", CR
ELSE
DEBUG CRSRX, 11, "...", DEC temp,
" times.", CR
ENDIF
