Ok finally got a chance to test the new compiler version tonight.

CCS PCH C Compiler, Version 5.062
Again this is a pic18f26k22.

Looks like it preserves FF5,FF6 and FF7 but not FF8.
Looking t ...

Cool switch thanks! had not noticed that one in docs before. Did a test with the sample code above and it did not seem to change the interrupt vector code it still skips the table registers.

The Li ...

looks like the compiler version you have did save the table registers and here is what I get no save.

Thanks! for doing the test.

As I mentioned I was stuck on this version because at the time o ...

meh.. much better and fewer errors but still I am getting corrupt data sometimes.

Maybe I missed some byte :(

I am using PCHL or Linux version.

The last dump was the interrupt vector generated just after the initial jump to program space. ...

PIC18F26K22. Most of ASM code is clear as day just like any I have done over the past 35 or more years but some of the PIC specific operations I am not well studied on such as the table read and write ...

Hmm maybe some idea.

I am now doing memcpy in my #INT routine moving data from code space to ram so this is doing a TBLPTR operation.

Now I am thinking this is a race condition and the registers ...

I am not sure what the feature is called but if someone knows it will I hope make googling a little easier. I am using Version 5.011 on Ubuntu as I have been for years. I have tried a newer compiler b ...

Hay all.

I have pchl and pcml and have a common code I am compiling for different pic chips, a 16f877 and a 18f2420.

I would prefer to not to have to change my /etc/ccsc.ini every time and k ...

I would like to put a few functions in a block of the pic that I can later call from my main code that I will upload later.

As an example my bootloader has usb_write and usb_read
I also use these ...

I have been trying to figure out a good way to keep all of my constant stings in ROM to free up as much program memory as possible.

This does not seem to work.

I am using pcml on an PIC16F877a ...

Sweeet....

thats a huge improvement thanks.

Thanks Frank very much what that is what I figured.

Reading the ASM code my test case used it sure didnt seem right.

The ASM output from your method looks right. Now can it be improved?

Anyo ...

It sounds like you want a light break alarm of sorts.

When the light beam no longer hits the light sensor a trigger happens..

What exactly does this have to do with 3hkz i dont understand what y ...

I do not believe this will work well for you if I understand your needs.

In your code you are only looking at your pattern on the byte boundary.

If your pattern exists on 2 bytes ie the lower ni ...
