Post by thread:[PIC]: lookup table pic16c74b

I desperately try to move my lookup tables into the second page (page1). I tried several pieces of code from the piclist source. The simulation shows that the first jump to the table occurs correctly, but instead of jumping to the second position, lookup returns directly although pclath and pcl are set correctly. Here's the code I'm currently using: ; select the table movlw high wel_data movwf look_hi movlw low wel_data movwf look_lo welcome call lookup clrf pclath ; set pclath call transmitw ; send w to the serial port addlw 0 ; check if w == h'00' == end of table btfss status,z goto welcome ; lookup routine lookup movf look_hi,w ; set pclath movwf pclath movf look_lo,w ; get pcl incf look_lo,f ; post increment skpnz incf look_hi,f movwf pcl ; jump now ; end lookup routin org 0x800 (somewhere in page1) wel_data dt "bla, bla, bla,...", h'0d', h'0a' dt "bla, bla, bla,...", h'0d', h'0a', h'00' Thanks , Robert -- http://www.piclist.com#nomail Going offline?
