I too would like to create some separate .o "object files" (want to put some of those special drivers into a library). I know that in MPLAB it can be done with the C18 and C30 compilers by ...

Thanks. Sometimes one forgets the basics (shift right and bit masking)!

a = 174;
MSnibble = a >> 4; // right shift to remove lower nibble
LSnibble = a & 0xF; // bit mask to remo ...

Does anyone have a quick and efficient way of converting a byte into two separate nibbles in CCS? Years ago on a different platform, we used to be able to:

int8 a, MSnibble, LSnibble;
a = 174; ...

Okay, as I understand it (and after re-reviewing the datasheet again), to control the display ON/OFF, underline cursor, or blinking; I must set the DB0, DB1, or DB2 data bits high while holdin ...
