About PCLK

Hamed Adldoost

Hi,

I have bought a LandTiger development board for LPC1768. it has a 12Mhz Xtal on it. I am trying to use its USART0 and I need to know PCLK. is it 3MHz? I devide 12 by 4. am I right?

    Try and error!? why? reading of the user manual is not more difficult than try and error. if you realize the structure of the PLL and clock section, you can set the desired baud rate with 0% error. in edition there is a configuration wizard in start up file that you can manage the system clock if you add it to your project.
