robinfawell Posted September 26, 2005 Report Share Posted September 26, 2005 Dear ThorstenI am back on the organ project after a summer break.It seems to me that I should be able to utilise the Dout shift register of my F0 meta group to record the toggle state of 3 push buttons. This requires a different behaviour to my radio groups ( now working).I have 3 buttonsFirst press sends sysex message; Second press sends a different sysex message. They are independent from each other. ;;GrpF0 (Not Radio Group): Deals with "single" Buttons where a given Din triggers a sysex message ;; The next Din is unused and allows a Cancel Sysex to be sent. MIDIO_META_Handler_F0 movf MIDI_EVNT1, W call MIOS_DOUT_PinGet; Has this Dout been set previously? btfss MIOS_PARAMETER1, 0 ; tests Dout state rgoto MIDIO_GRPF0_SYSEX_SEND addlw 0x01; adds 1 to W thus increasing MIDI_EVNT by 1 call MIOS_DOUT_PinSet0 rgoto MIDIO_BANKSTICK_DUMP_GET MIDIO_GRPF0_SYSEX_SEND movf MIDI_EVNT1, W call MIOS_DOUT_PinSet1 rgoto MIDIO_BANKSTICK_DUMP_GETThis works to some extent then causes the PC to crash. Please comment.Regards Robin Quote Link to comment Share on other sites More sharing options...
robinfawell Posted September 27, 2005 Author Report Share Posted September 27, 2005 I have managed to make the program work with the following codeGrpF0 (Not Radio Group): Deals with "single" Buttons where a given Din triggers a sysex message ;; The next Din is unused and allows a Cancel Sysex to be sent. MIDIO_META_Handler_F0 movf MIDI_EVNT1, W call MIOS_DOUT_PinGet; btfss MIOS_PARAMETER1, 0 ;Has this Dout been set previously? (tests Dout state) rgoto MIDIO_GRPF0_SYSEX_SEND movf MIDI_EVNT1, W call MIOS_DOUT_PinSet0 ; set LED to off movf MIDI_EVNT1, W addlw 0x01 ; to change the Din by 1 rgoto MIDIO_BANKSTICK_DUMP_GET MIDIO_GRPF0_SYSEX_SEND movf MIDI_EVNT1, W call MIOS_DOUT_PinSet1 movf MIDI_EVNT1, W rgoto MIDIO_BANKSTICK_DUMP_GETIt seems as if I must keep inserting the "movf MIDI_EVNT1, W" line before any MIOS_DOUT line. Do these call statements destroy WREG values?Regards Robin Quote Link to comment Share on other sites More sharing options...
