DIN trouble

[spongebob]

I have some strange situation with DIN module. device sends wrong commands.

source:

void DIN_NotifyToggle(unsigned char pin, unsigned char pin_value) __wparam
{
  // a button has been pressed, send Note at channel 1
  MIOS_MIDI_BeginStream();
  MIOS_MIDI_TxBufferPut(0x90); // Note at channel 1
  MIOS_MIDI_TxBufferPut(pin);  // pin number corresponds to note number
  MIOS_MIDI_TxBufferPut(pin_value ? 0x00 : 0x7f); // buttons are high-active
  MIOS_MIDI_EndStream();
} 

reaction on button press:

1st SR

pins:

1: [90 00 7F] Channel 1: Note On C-1 velocity: 127

    [90 00 00] Channel 1: Note On C-1 velocity: 0

2: [90 01 7F] Channel 1: Note On C#-1 velocity: 127

    [90 01 00] Channel 1: Note On C#-1 velocity: 0

3: no reaction

4: no reaction

5: no reaction

6: [b0 4C 3D] Channel 1: CC Sound Controller 7 value: 61 (only on button release)

7: no reaction

8: no reaction

2nd SR - all pins work fine

3rd SR

pins 1 and 2 - work fine

3: [b0 3A 3F] Channel 1: CC LSB 26 (Undefined) value: 63

    [b0 3A 41] Channel 1: CC LSB 26 (Undefined) value: 65

4: [b0 3A 41] Channel 1: CC LSB 26 (Undefined) value: 65

    [b0 3A 3F] Channel 1: CC LSB 26 (Undefined) value: 63

5,6,7,8 - work fine

4th SR

pins 5,6,7,8 - work fine

pins 1,2,3,4 only react on button release and send random commands.

I changed SR with each other, but the result has not changed

trouble was in application.

solved.
