Lpc2000

Hi,

I want to generate a small interrupt program using LPC 2292. The LED should be ON for 2 sec and be OFF for 1 Sec.I would like to know what values should I load into T0MR0 and T0PR register to create a delay for 1 Sec.?Is there any forrmula to calculate the Timer load values for T0MR0 and T0PR for different Oscillator frequency?

looking for all ur help.

thanks

this ist what i use: 

f(Hz) = (pclk / (T1MRO+1))

the values are depends on the pclk ! for more information look at the 
hitex lpc2000 tutorial

Philips ARM7-Based Microcontrollers
")

Hope this will help you!
