SK40C Beginner

[vick5821]

Hey guys, I have just got my SK40C today!!! Damn excited.However, I do not know how to start ? I downloaded the code from cytron tutorial websites but it build failed in MPLAB IDE..

how to solve it ?

This is the error msg

Printscreen the whole MPLAB IDE, show us the project window.

It is because your compiler does not recognize the library of "system.h" for your MC. Based on my experience, i am using PIC16F877A and using the library as same as you do but after I removed the library, it works and my program working as I expected. I think it is because of your MC do not have such library to call. I hope it helps you

Is these enough? Please help me ! Always build failed!

Then what should I do ?

OK, there are several reasons and you have solved some of the problem. I think earlier, you did not open the project file, and you create the project yourself without adding the system.h into project window. That is normal mistake.

Now, you can compile but you got this:


This is due to different version of Hi-tech compiler. We do not know why Hi-Tech change the label when they upgrade to different version. The sample code in tutorials is being compiled using Hi-Tech C compiler v9.80. You are using v9.83.

Try replace this:

__CONFIG(HS & // External Crystal at High Speed
WDTDIS & // Disable Watchdog Timer.
PWRTEN & // Enable Power Up Timer.
BORDIS & // Disable Brown Out Reset.
MCLREN & // MCLR function is enabled
LVPDIS); // Disable Low Voltage Programming.

with this:

__CONFIG(FOSC_HS & // High Speed Crystal.
WDTE_OFF & // Disable Watchdog Timer.
PWRTE_ON & // Enable Power Up Timer.
BOREN_OFF & // Disable Brown Out Reset.
MCLREN_ON & // Enable MCLR
LVP_OFF); // Disable Low Voltage Programming.

in the c code. Compile again, it should solve the problem, at least this problem

Ober, you are right, I have that problem too. Why is HI-TECH changing it? Really not convenience to us. I have to change all my old code accordingly. Worst, they also change some of the register name, such as ADGO become AD_GODONE.

CODE: SELECT_ALL_CODE

#include <pic.h>

__CONFIG ( 0x3F32 );

#define LED_1 RC3
#define LED_2 RC2
#define LED_3 RA0

void init(void);
void delay(unsigned long data);

void main(void)
{
init();


for(int i=0;i<3;i++)
{
LED_1=1;
LED_2=0;
delay(100000);
LED_1=0;
LED_2=1;
delay(100000);
LED_1=0;
LED_2=0;
LED_3=1;
delay(100000);
LED_1=0;
LED_2=1;
LED_3=0;
delay(100000);
}
for(int j=0;j<3;j++)
(
LED_1 =1;
LED_2=1;
LED_3=1;
delay(100000);
}




void init()
{
TRISA=0b00000000;
TRISB=0b00000000;
TRISC=0b00000000;
TRISD=0b00000000;
TRISE=0b00000000;

}

void delay(unsigned long data) //delay function, the delay time
{
for( ;data>0;data-=1); //depend on the given value
}

This is my code, and this is how it operate..Weird working based on code right? anyone can tell me why ?

for(int j=0;j<3;j++)
(
LED_1 =1;
LED_2=1;
LED_3=1;
delay(100000);
}

If you are expecting the above code to flash the 3 LED for 3 times, you wont be able to get it. Think about it over carefully. The rest of the video matches your code.

I try changing it..but got some error too
