Hi there ... I have to implement several lookup tables of 256 values. I split the tables in parts of 128 values bit have a page select problem ... program crashes ... does anyone has an example program or can explain me more in detail how i can do this ? here is a part of my soft: LUT.ASM ************************************************************************ ********************* org 0xC00 LUT1 addwf PCL,f retlw 0x000 ... 128 values org 0xD00 LUT2 addwf PCL,f retlw 0x008 ... 128 values org 0xE00 LUT3 addwf PCL,f retlw 0x010 ... 128 values I now access the table by doing: ; bsf STATUS,RP0 ; movlw 0x00D ; movwf PCLATH ; ; bcf STATUS,RP0 ; movfw GOVALUE ; ; bsf STATUS,RP0 ; call LUT2 ; movlw 0x000 ; movwf PCLATH ; ; bcf STATUS,RP0 ; movwf RETURNVALUE Thanks in advance ! And happy PICing Bart
