Stuck with programming midibox

MIOS programming (Assembler)
1

Hello,

Can someone help me with solving the following problem when pogramming my midibox?

I’ve managed to upload the bootstrap and the MIOS-OS. No complaints @ all.

Now I’m trying get upload my application to test if all of my 16 endless rotary encoders are working.

I’ve made the following changes in the mios.tables.inc

     ;; encoder entry structure

ENC_ENTRY MACRO sr, din_0, mode

     dw      (mode << 8) | (din_0 + 8*(sr-1))

     ENDM      

ENC_EOT      MACRO

     dw      0xffff

     ENDM

MIOS_ENC_PIN_TABLE

     ;; encoders 1-16

     ;;        SR  Pin  Mode

     ENC_ENTRY  1,  0,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 1

     ENC_ENTRY  1,  2,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 2

     ENC_ENTRY  1,  4,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 3

     ENC_ENTRY  1,  6,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 4

     ENC_ENTRY  2,  0  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 5

     ENC_ENTRY  2,  2,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 6

     ENC_ENTRY  2,  4,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 7

     ENC_ENTRY  2,  6,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 8

     ENC_ENTRY  3,  0,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 9

     ENC_ENTRY  3,  2,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 10

     ENC_ENTRY  3,  4,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 11

     ENC_ENTRY  3,  6,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 12

     ENC_ENTRY  4,  0,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 13

     ENC_ENTRY  4,  2,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 14

     ENC_ENTRY  4,  4,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 15

     ENC_ENTRY  4,  6,  MIOS_ENC_MODE_NON_DETENTED      ; V-Pot 16

     ;; encoders 17-32

     ENC_EOT

     ENC_EOT

Now only the first encoder gives a signal in MIOS but the other 15 don’t.

I’ve got a DIN module right @ the CORE @ pin 9 with 16 ALPS encoder to it.

I think my code isn’t ok but I can’t find the problem.

My final design contains 96 buttons, 16 encoders, 17 sliders and 38 leds. Which example from the ucapps-site should I use to re-write.

Is somebody help me programming this thingie?

thanx

Did you try the ENC example 1?

Then you should continue with ENC example 2 which handles more than 1 encoder… (it always makes sense to read the comments in main.asm ;-))

Best Regards, Thorsten.

Thanx Thorsten,

I just re-edited the ‘mios_tables.inc’ from the encoder1 example but didn’t read the info in the ‘main.asm.’

I’ll have a look @ it and will try it again… :smiley:

Hi,

WHere can i get more infomation for editing the mios_tables.inc file?

With trial and error i only concluded that

MT_ENTRY      0x90, 0x00 - is a note &

MT_ENTRY      0xb0, 0x00 - is a controller.

Is there some where that lists out what the rest like 0x00,0x01… are used to patch to?

Cheers. :slight_smile:

Hi,

Just fire up Google and search for “midi specification”…

What you are looking for:

8 = Note Off

9 = Note On

A = AfterTouch (ie, key pressure)

B = Control Change

C = Program (patch) change

D = Channel Pressure

E = Pitch Wheel

The lower Nibble (4 Bits) is the MIDI-Chanel:

0x92 means Note On, Channel 2

0x8F means Note Off, Channel 16

Hope this helps

Thanks for the list.

I’ve getting some problems. I connected 8 pots to a AIN4X. I’m using the MIOS AIN64 DIN128 DIO128 app.

In the mios_table, i put “MT_EOT” for the pots section. THen for the first eight i placed :MT_ENTRY 0xb0, 0x10-18.

The problem is, when i open one of 2 certain pots, i get lots of random data. When all closed, i can only work 4 pots. But each of this pot sends 2 sets of sysex eg B0-14 and B0-15 or B0-13 and B0-17 for another pot.

What’s went wrong?

Hey intosite,

you have to connect the unused J’s of your AIN4 to ground

Do i still have to do that after i do the MT_EOT in the mios-table.ini file?
