Program Compilation Error
« on: August 06, 2009, 09:54:19 AM »
I'm writing a program to create an pulsing effect by using the led in axon mcu. The following, is the code in the control.c file.

Code: [Select]
void control(void)
{
ledpulse();
}
void ledpulse(void)
{
int i;
PWM_Init_timer1_LED(8);
PWM_timer1_On_LED();
while(1)
{
for(i=110;i<255;i++)
{
PWM_timer1_Set_LED(i);
delay_ms(10);//control pulse speed
}
for(i=255;i>110;i--)
{
PWM_timer1_Set_LED(i);
delay_ms(10);//control pulse speed
}
}
}

I have not changed anything in the Axon.c file. I've changed the target name in the makefile. I get the following error.

it looks like you didn't include a header file for the PWM functions, its saying that those aren't defined anywhere
use the google.  it's your friend.

i dont know what file the axon one is in, but to include it you would do something like
Code: [Select]
#include "pwm_file_name.h"

this should go at the top of your code
use the google.  it's your friend.

oh okie man, thanks.

can any users of axon guide me on finding the header file for pwm functions??

Its in timer640.c

http://www.societyofrobots.com/axon/axon_function_list.shtml#pwm

Do i need to add the header file timer640.h in the axon.c file ?

It should already be there.

What code version are you using? This doesn't work on earlier code versions.

no admin, i tried adding the header file timer640.h and still i get the same error. I'm using version 1.08.

ok so it appears it got broken when the PWM file was entirely rewritten . . .

Until I fix it, just add this code at the top of control.c, right after the variables are called, and it should work. It compiled fine for me, but I didn't test to see if it worked.

Code: [Select]

#ifndef PWM10
// mega128 PWM bits
#define PWM10 WGM10
#define PWM11 WGM11
#endif

//OC1B  pin B6 (attached to green LED)
void PWM_Init_timer1_LED(u08 bitRes)
{
// enable timer2 as 8,9,10bit PWM
if(bitRes == 9)
{ // 9bit mode
sbi(TCCR1A,PWM11);
cbi(TCCR1A,PWM10);
}
else if( bitRes == 10 )
{ // 10bit mode
sbi(TCCR1A,PWM11);
sbi(TCCR1A,PWM10);
}
else
{ // default 8bit mode
cbi(TCCR1A,PWM11);
sbi(TCCR1A,PWM10);
}
// clear output compare values
OCR1B = 0;
}

//on commands
void PWM_timer1_On_LED(void)
{
sbi(TCCR1A,COM1B1);
cbi(TCCR1A,COM1B0);
}


//off commands
void PWM_timer1_Off_LED(void)
{
cbi(TCCR1A,COM1B1);
cbi(TCCR1A,COM1B0);
}

void PWM_timer1_Set_LED(u16 pwmDuty)
{OCR1B = pwmDuty;}

thnx admin! It worked.  ;D
Can you work on this pwm error as soon as possible? If u can, it would be nice ;)

Well, since this quick hack fixes it, its now a low priority bug fix.

I'll make sure it works correctly with the next code version release.
