I fogot put #int_TIMER1 in function.
*************************************************************
Hi ever body.
In the code below when I enable interrupt TIMER1 the program enters an infinite loop. But it works ok without interruption.
Can anyone help?
Thanks in advance.
| Code: | #include <16F630.h>
#FUSES NOWDT // No Watch Dog Timer
#FUSES HS // High speed Osc (> 4mhz for PCM/PCH) (>10mhz for PCD)
#FUSES NOPROTECT // Code not protected from reading
#FUSES NOBROWNOUT // No brownout reset
#FUSES MCLR // Master Clear pin enabled
#FUSES NOCPD // No EE protection
#FUSES PUT // Power Up Timer
#use delay(clock=20000000)
#use rs232(baud=9600,parity=N,xmit=PIN_A2,rcv=PIN_C0,bits=8, ERRORS)
