I want to enable timer2 to be able to use pulse width modulation. I am using PIC18F87J11 with internal 8MHz oscillator. I have minimum knowledge about PIC programming, so I want to know what else is missing in my code to enable the timer.
#define TMR2_IF PIR1bits.TMR2IF
#define TMR2_IE PIE1bits.TMR2IE
#define TMR2_IP IPR1bits.TMR2IP
#define TMR2_CON T2CON
Let's say this is my main code for now
void main()
{
TMR2_CON = 0b00000100 | CLOCK_DIVIDER_SETTING; // CLOCK_DIVIDER_SETTING = 4
TMR2_IF = 0;
TMR2_IE = 1;
TMR2_IP = 1;
while(1);
}
The rest of the code that I don't yet know where to place it.
if(TMR2_IF)
{
printf("\r\nHello");
if(TMR2_IE)
{
TMR2_IF = 0;
}
}
Do I need an Interrupt Service Routine? If Yes, how do I add it? Remember my goal is to use the PWM which I still did not get there yet, but for now I want to make sure the settings for timer2 are correct.
What else is missing?
Thanks in advance!
change the while(1);
to
while(1)
{
if(TMR2_IF)
{
printf("\r\nHello");
if(TMR2_IE)
{
TMR2_IF = 0;
}
}
}
