"Extending" timer1

[aratti]

but where would I put the variable increment in my code example?

Naturally in your interupt routine. Let assume you have a variable Tmr1Z (declared as Word) and you increment TMR1Z by 1 at each overflow then TMR1L & TMR1H and TMR1Z will give you a 32 bits count from which you could pullout a lot of information.

Also y = y + 525 could be used but since y will overflow itself after 124 timer1 overflow is not very helpfull.

100k or a million makes a difference.

One is ten times the other! 100K makes life even more difficult.

For pic 16F676 this is what datasheet report:

- 100,000 write FLASH endurance
- 1,000,000 write EEPROM endurance
- FLASH/Data EEPROM Retention: > 40 years
