PostForum: General CCS C Discussion   Posted: Tue May 17, 2011 6:56 pm   Subject: Bus over power supply
If I recall this is what X10 is based on?

In my line of work they can transmit it over HV transmission lines, miles long at 230kV, using what's called Power Line Carrier (PLC). Although this is now ...

PostForum: General CCS C Discussion   Posted: Sun May 08, 2011 11:27 am   Subject: time trigger
I recently made a similar system where I used a 1ms interupt, where it just increments a 16 bit counter. I wrote my own ISR to make it tight, took some time but got it done. I had an issue with the fa ...

PostForum: General CCS C Discussion   Posted: Tue Mar 01, 2011 12:28 pm   Subject: timer 2, 4 & 6 issues
I wrote one for a 1ms TMR INT, but now do my interupt handlers (GLOBAL INTS) manually, using ASM where required.

It was more work and lots of re-reading of the data sheet, but I now have a better ...

Normally, if the #use delay definition is wrong. 'delay', will give an 'undefined identifier' error.
The fact that moving the statement, doesn't change things, suggests the fault is not an earlier sy ...

Still get the error if I move the delay around in main.

Remove it and all is good. I started removing functions and no change, I will start trimming the code to bare bones until I solve it.

PostForum: General CCS C Discussion   Posted: Mon Jan 24, 2011 10:45 pm   Subject: Error 76 Expect ; ......Warning code has no effect (SOLVED)
I'm using ver 4.106 on a PIC18F2585

The code compiles and runs fine, but when I add a CCS delay

delay_ms(500);

I get the error 76...Expect; along with warning 207 "code has no effect&quo ...

I think more importantly you should only be reading the timer value once, and work from the stored value in your timer test routine.

The way I am reading the code in the source as published is you ...

PostForum: General CCS C Discussion   Posted: Wed Dec 22, 2010 11:59 pm   Subject: Issue with <= statement
Well I am trying to create a general timer array using TMR1 with a PIC18F2585. I config'd TMR1 with a 1ms interrupt and inc's a counter. So far so good as I scoped the TMR1 int at 1ms.

I toggled a ...

PostForum: General CCS C Discussion   Posted: Wed Dec 22, 2010 3:02 pm   Subject: >= and others
So is this <= or >= statements a known bug?

I don't use any CCS functions as I like to roll my own.

I'm using 4.106 on a PIC18F2585 and finally found a "random" issue with my cod ...

PostForum: General CCS C Discussion   Posted: Sat Nov 13, 2010 6:35 pm   Subject: INT_GLOBAL vs INT_FAST vs INT_HIGH on 18F parts
I did some reading but have a couple of Q's regarding priority ints on 18F devices.

I am playing with a 18F2585 on CCS 4.106

I think I understand the following:

1) Using INT FAST will allow a ...
