You could just use the prescaler, but this limits count resolution, as you can't read the prescaler. On parts other than the 5x series, the other way is to generate an interrupt on the TMR0 rollover and keep a high-byte in software. It is also possible to use a hybrid of these methods (i.e prescaler + software count), depending on applications requirements. -- http://www.piclist.com hint: To leave the PICList .....piclist-unsubscribe-requestKILLspam@spam@mitvma.mit.edu

Hello sir Mike! =) What I meant what that using the TMRO for longer delays, how do I do it? Isn't it that the TMR0 can count up to a maximum of 255 only? How could I make it count up to 65535? Are there any example codes I could use as basis? Thank you so much. Kindest regards. Have a nice day to all! "Jose S.

You can set up TMR0 to interupt when it overflows (from 0xFF to 00). Keep an 8-bit variable that you increment every time the interrupt occurs. You can use TMR0 as the low-order 8 bits and the variable as the high-order 8 bits. Dale On Mon, 16 Apr 2001, Jose S.

Got it! =) Thank you so much! Dale Botkin <spamBeGonedalespamBeGoneBOTKIN.ORG> wrote: You can set up TMR0 to interupt when it overflows (from 0xFF to 00).

Use the prescaler - look at the description of the OPTION register for how to set this up. If you set the prescaler to 256, TMR0 will only increment on every 256th clock (internal or external, as configured) -- http://www.piclist.com hint: To leave the PICList RemoveMEpiclist-unsubscribe-requestspam_OUTKILLspammitvma.mit.edu
