LCD message update fasterPosted by wne on September 8, 2009 Port: PIC32. Hardware: explore 16 I changed the timer1 to timer3 with three places in port.c file: 1. interrupt vector extern void __attribute__( (interrupt(ipl1), vector(_TIMER_3_VECTOR))) vT1InterruptHandler( void ); 2. timer setup OpenTimer3( ( T3_ON | T3_PS_1_8 | T3_SOURCE_INT ), ulCompareMatch ); ConfigIntTimer3( T3_INT_ON | configKERNEL_INTERRUPT_PRIORITY ); 3. interrupt flag reset mT3ClearIntFlag(); After running, found that the LCD message update faster then before. why? Thanks. RE: LCD message update fasterPosted by MEdwards on September 8, 2009 You don't say what the timer is doing so I presume it is the tick interrupt? Also you don't say what is on the LCD, is it displaying an error? Is the timer being used by any other part of the demo? Some demo applications have a high frequency timer. Maybe there is a conflict. RE: LCD message update fasterPosted by wne on September 8, 2009 I know why, the timer3 is being used by other task.
