I believe the compiler interprets the line iorwf ticksHi as iorwf Sun, 08 Nov 2009 12:51:04 GMT cdb http://tech.groups.yahoo.com/group/picmicrodevelopersforum/message/1842 http://tech.groups.yahoo.com/group/picmicrodevelopersforum/message/1842 Part of your problem is that the test for the counter being zero should be a wrapper to the code that actually decreases the counter.

I'm trying to decrement a 16-bit counter using a 16F627A, and I'm confused about the function of the Carry bit to Mon, 02 Nov 2009 01:59:27 GMT Mike Dodd http://tech.groups.yahoo.com/group/picmicrodevelopersforum/message/1840 http://tech.groups.yahoo.com/group/picmicrodevelopersforum/message/1840 ... Thanks for your suggestions. I discovered the problem was that I needed to turn on the peripheral interrupt enable bit (PEIE) as well as the global Sun, 01 Nov 2009 18:49:42 GMT orwill@... http://tech.groups.yahoo.com/group/picmicrodevelopersforum/message/1839 http://tech.groups.yahoo.com/group/picmicrodevelopersforum/message/1839 Mike, I don't use that particular processor, but it is similar to others that I have used so I think I have the things below correct. One problem I see is that Sun, 01 Nov 2009 15:41:22 GMT Mike http://tech.groups.yahoo.com/group/picmicrodevelopersforum/message/1838 http://tech.groups.yahoo.com/group/picmicrodevelopersforum/message/1838 ... org resetVector goto initialize ; Interrupt service routine. org interruptVector bcf T1CON, TMR1ON ; Turn off Timer1 bsf PORTA, Thu, 08 Oct 2009 15:51:29 GMT chandra_131 http://tech.groups.yahoo.com/group/picmicrodevelopersforum/message/1837 http://tech.groups.yahoo.com/group/picmicrodevelopersforum/message/1837 I am using 24hj128gp306 and want to establish connection with PC terminal programm at 115200bps.PIC24HJ I am using UART2.

Well, I need the I/O pin for actual I/O. ... Same in this case -- I can't afford to use I/O pins for the oscillator. ... Thanks.

The programming issue turned out to be what we figured it was - the configuration bits were changed. I use two laptops to
