Hi Guys,
Just tried to download this code but I keep getting the following message:
*** Error 160 "E:\Marks D drive\PIC_LIBRARY\C_FILES\Examples\Graphic LCD\T6963CCS\glcdex1.c" Line 297(0,1): External symbol not found DisplayMode
1 Errors, 0 Warnings.
It does not compile. Can anyone spot where I have gone wrong please.
Cheers
Mark |

He has declared some variables with the 'extern' qualifier.
At the time he wrote his program, the CCS compiler accepted 'extern'
but ignored it. Since then (in late versions of 3.xxx, according to the
readme.txt file), it accepts 'extern'. This was in preparation for vs. 4.0.
Solution:
Find the lines where variables are declared as 'extern' and delete that
keyword only, leaving everything else in those lines unchanged. |
