pic 24fj pll settings and rs232 and lcd problem!

[scalebor]

hi,
I use pic24fj256gb110 device. When i configured pll settings, rs232 baud rate is problem. I can not connect to pc. I tried every baud rate, but not. I see my delay_ms() function is too slow. I write 1000ms but it is 8-9 s. I don't understand what the problem is.

#FUSE PR_PLL

sorry , i allready use PR_PLL.i wrote wrong.

You are not selecting a primary oscillator.....

On these chips the PR_PLL setting, says 'use the primary oscillator with PLL', and PLL2, says 'divide the clock by 2 to feed the PLL'. However you need to also say what oscillator 'type' you want the primary to be. XT - for 8MHz. Currently you have no primary oscillator type selected (so default to NOPR), and this won't start. The chip will therefore 'fall back' to using the internal RC.....

You can always see what is happening, by looking at the end of the .LST file at the programmed fuse list. With:

#FUSES PR_PLL, PLL2

The fuse list shows:

[scalebor]

#FUSES WPOSTS1
#FUSES NOWINDIS
#FUSES NOJTAG
#FUSES XT
#FUSES CKSFSM
#FUSES PR_PLL
#FUSES PLL2
#use delay(clock=32000000)

i use this settings but it is same problem. if i want to use 1sn delay,i use 250ms delay.
delay_ms(250) = 1 second delay.

This means your primary oscillator is not starting.
You can 'prove' that this is the problem, by selecting NOCKSFSM. If the chip doesn't start, then something is wrong with the oscillator. Currently if the primary doesn't start, it'll drop back to the internal oscillator.
I'd say you possibly have a connection problem with the primary oscillator.
