PIC16F690 Lookup Error

[RunningMan]

Hi all:

I am using a 16F690 with 4K word of code space and am running into an issue using more than 4 lookup tables with 255 values each.

I am compiling to 2652 words, but the compiler is spitting out errors like mad. I have searched like mad on the forum for a workaround but I am not having any luck..

if I back down to 4 lookup tables the errors go away.

Can anyone point me to a workaround on the forum? I am lost.

Hi,

Please post the compilation errors you are getting.

Hi,

It seems that the code is compiling past the maximum available memory. The warnings should not cause panic. Have you tried using MPASM ?

As large files are compiled and then
assembled, they may start to use more than the first page. As each
page is used, PM, the assembler, will issue a message that the code is
crossing a particular boundary. This is normal and no cause for alarm.
PBP will make sure to take care of most of the issues for you.

However a look at your entire code may give some insight as to why it is crossing the maximum usable prog mem or if it is just a warning.

I am compiling using MPASM in Microcode Studio with PBP 2.47

Hi,

I can try compile and tweak if you post your code. What happens if you remove some code (say a subroutine) to test if it compiles okay.
