Re: EEPROM memory

Hi
I'll read your info later but say in a PIC12F629, where should I write or store data in the eeprom what are the address numbers. I seem to be getting errors when I compile my code. Is there a fixed block of numbers I should be using?

EEPROM memory

Just a quickie

Re: Timers and TMR0

Hi The 509A is about a third of the price of an 84A and for most small projects they are ok, I think it's a waste using larger chips in small projects. Obviously it depends on the number of pins one needs. I find that the timer is the most difficult to learn and come to grips with. Unfortunately I k...

Re: Timers and TMR0

Hi Philba I use an 84F to do my developement on and by using the files common to the 509A I can translate from one pic to the other. When my program works I burn it into the 509A. If I understand you right is it just a matter of Clearing TMR0 to start it and then copying TMR0 to W then storing it in...

Timers and TMR0

Hi
I am trying to learn about TMR0 in a pic 12C509A.
I would like to detect a high on one of the pis then start the timer. When a low is detected the timer must be stopped and the valued stored in a file.
Any help would be appreciated

Re: Waterlevel controller

Hi<p>Basically my mother who is getting on, forgets the bath tap running with the usual catastrophic results, so I thought of a unit, maybe battery operated that could be hung on the edge of the bath and would give an audible warning when a preset level is reached. While I was about it I thought of ...

Re: 12C509 programming

Hi
I learnt to program them and use them regularly. Do a Google search for Talking Electronics in Australia and order their cd. This is the best micro controller course I have seen.<p>Mac
