You need to load the following registers first:
TBLPTRL
TBLPTRH
TBLPTRU
then you need to use
tblrd * or
tblrd *+ or
tblrd *-
Read data to latch.
Finally, you can get data by
movf TABLAT, W, 0 or
movff TABLAT, location

Hello,
anyone has suggestions on the best way to read data stored in program memory using SDCC/PIC16?
in assembly I would use a DB directive, TBLPTR and the table read istruction..
I was planning to keep using the DB directive, assemble with gpasm -c into an object file, and loading the data from C.
