Hi Tk and thank you for your suggestion. Is not possible for me to compile with the code you gave me because MPLAB return to me with this error: MAIN.ASM 289 : Symbol not previously defined (this_value) something like the "this_value" not recognize... This is the entire code ( related to pot section) USER_AIN_NotifyChange JUMPTABLE_2BYTES 2 ; (2 entries because in this trying we use only 2 unmuxed AIN) rgoto Function_for_WREG_00 ; AIN 0 rgoto Function_for_WREG_01 ; AIN 1 rgoto AIN_END rgoto AIN_END rgoto AIN_END; rgoto AIN_END; rgoto AIN_END rgoto AIN_END ;;;;;;;;;;;;************************************** ; ;;;;;;;;;;;;************************************** Function_for_WREG_00 ; 0-127_AIN 0 movlw 0xb0 call MIOS_MIDI_TxBufferPut movlw 0x53 call MIOS_MIDI_TxBufferPut movlw 127 btfss this_value, 6 ; bit 6 is set on values >= 64 movlw 0 call MIOS_MIDI_TxBufferPut Function_for_WREG_01 ; 0-127_AIN 1 movlw 0xb0 call MIOS_MIDI_TxBufferPut movlw 0x54 call MIOS_MIDI_TxBufferPut movlw 127 btfss this_value, 6 ; bit 6 is set on values >= 64 movlw 0 call MIOS_MIDI_TxBufferPut AIN_END I can't understand where's the error... Thank you very much! Bye Dexter

Hi I'm trying to porting a MIOS application wrote in C to ASM. All work just done but i need an help on this: In my hardware I'm using a 2 position switch on an AIN unmuxed and it is working good with C allowing it to assume only value 0 or 127. I'm not able to translate in ASM. My C code ( in pot section ) is: { // Only allow value 0 or 127 this_value = this_value < 63 ? 0 : 127; // If valid, send CC out MIOS_MIDI_TxBufferPut(0xb0); MIOS_MIDI_TxBufferPut(53); MIOS_MIDI_TxBufferPut(this_value); } Any help to make the same thing in ASM under the section USER_AIN_NotifyChange? In this moment I'm using the mios_table.inc for specify the midimessages of the pots. thank you very much. Dexter

Yes thank for reply I already know qbas 32x32 but that application is wrote totally in asm, but sm_c_example2_v1c, in my opinion is more powerful and let me do modification in easier way. That's because only the matrix driver ( sm_fast.asm ) is wrote in asm and the main program ( main.c )is in C. In this way, when I have the sm_fast.asm expandend ( because I need more that 64 switches )for example from 8x8 to 16x16, changing code in main.c for example: ORIGINAL CODE MIOS_MIDI_TxBufferPut(0x90); MIOS_MIDI_TxBufferPut(pin); MIOS_MIDI_TxBufferPut(value ? 0x00 : 0x7f); As result I can simply change the midi messages putting the one I want. 32x32 is not so easy, there's velocity and other things very difficult! bye Andrea

Hi I'm searching a way for expand the original sm_fast.asm that is 8x8 matrix to a 8x16 or 16x16 (obviously adding din and dout module) anyone can help me to modify it? Thanks in advance. :smile: bye

Hi to all the forum I'm here after 3 years of stop! I'm very happy about the news on midibox ( stm32 and so on ) keep the community increase! DIY passion bring me another time! After all this years I'm considering build a midi controller for an old keyboard I get from a friend of mine. Keyboard is from an old Italian manufacturer called CRB, it is not working but I'm considering to transform it to a midi controller. This is my first and only problem. All keybed are arranged in matrix 8x8 and I find that the application sm_C_example2_v1c work perfectly for me! ( I don't need velocity or so on...)just for one keyboard. I have only one pic core but a lot of din dout shift registers, so I wonder if is it possible to increase the application for manage 2 keyboards: in fact 8x8 uses only one din and one dout and I have available 4din and 4dout ( 2 complete din and dout module!). I already look at 32x32 code and so on but they are coded with old toolchain and all in ASM, on the other hand sm_c_example2_v1c is easy because the code in ASM only manage the matrix driver and the main.c manage midimessages is in C and so I can reuse the main.c for adding pots or for adding other buttons for sending ( for example ) CC instead of note ON OFF messages. Adding one 74hc165 and one 74hc595 can change matrix from 8x8 to 16x16 but this involved changing the ASM code: how can I do it using the same app? Any help will be appreciated! bye! Andrea
