time=get_timer0();
//this will read the timer0 register
//value
Timer1
These options lets the user configure and use timer1. The clock/counter is 16-bit on pic16s and
pic18s. It counts up and also provides interrupt on overflow. The options available differ and are
listed in the device header file.
Relevant Functions:
setup_timer_1(mode)
set_timer1(value)
value=get_timer1
Relevant Preprocessor:
None
Relevant Interrupts:
INT_TIMER1
Relevant Include Files:
None, all functions built-in
Relevant getenv() parameters:
TIMER1
Example Code:
For PIC18F452
setup_timer_1(T1_DISABLED);
Disables or sets the source and prescale for
timer1
Initializes the timer1 clock/counter
Returns the value of the timer1 clock/counter
Interrupt fires when timer1 overflows
Returns 1 if the device has timer1
//disables timer1
or
setup_timer_1(T1_INTERNAL|T1_DIV_BY_8); //sets the internal clock as source
//and prescale as 8. At 20Mhz timer1 will
increment
//every 1.6us in this setup and overflows every
//104.896ms
set_timer1(0);
time=get_timer1();
58
//this sets timer1 register to 0
//this will read the timer1 register value
