Hi, Iam working on LPC248 OEM board ,where iam testing the delays in RTX kernel.
In configuration file i set the value as shown below.
#define OS_TICK 10000
Can anybody explain what is the meaning of this?
In
os_dly_wait(100)
i kept 100 as sytem ticks.
The above delay work as 1sec delay.
My aim is to get the delay of 1sec ,what are the changes i needed in configuration file?
With what you show, you should be getting a 10 second delay. Your OS_TICK is too large (It should be 10000) to have os_dly_wait(100) to give a 1 sec delay.
sorry Robert,
It is not working even if i changed to 10000. Iam getting two printed count values within 1 sec.
I have doubts on the below values
#define OS_TIMER 0 #define OS_CLOCK 12000000
How can i set the correct values.
The code is what i used for configuring the PLL
/* Fcck = 57.6Mhz, Fosc = 288Mhz, and USB 48Mhz */ #define PLL_MValue 11 #define PLL_NValue 0 #define CCLKDivValue 4 #define USBCLKDivValue 5 /* System configuration: Fosc, Fcclk, Fcco,Fpclk must be defined */ /* PLL input Crystal frequence range 4KHz~20MHz. */ #define Fosc 12000000 /* System frequence,should be less than 80MHz. */ #define Fcclk 57600000 #define Fcco 288000000 /* APB clock frequence , must be 1/2/4 multiples of ( Fcclk/4 ). */ #define Fpclk (Fcclk / 2)
This is what i have done in my code.
My goal is verifying the delays with real time clock. I want to see the printed count values for 1 sec which was compared to real time.
If i give any trouble sorry for that!!
