decrease a Encoder just in Software

MIOS programming (C)
1

Hi

Im trying to decrease a Encoder just in Software for a reason of a Menu that has to be chosen before i can edit the parameters manualy.

What i tried is to start this on pressing a button:

} else if( button_id < 0x7f ) {	// Range SAC_Special

      ENC_NotifyChange(8,2)

  }

the 8 is meant for the Encodernumber i need to decrease for 2 Detents. and i thought that it will jump to Main.c where this is the Encoder function:

void ENC_NotifyChange(unsigned char encoder, char incrementer) __wparam

well, the main question is: how can i decrease a Enc. virtualy?

Thanks for help

Best regards

Well as usual… as soon as i give up, i find the solution I’m searching for ages.

// 0x58..0x7f could be used for other purposes

  } else if( button_id < 0x7f ) {	// Range SAC_Special

      MM_VPOT_SendJogWheelEvent(-1);

  }

That helps to decrease. But it decreases 3 clicks, not one. Does somebody know how to make smaller steps?

You have to check if the button has been pressed (pin_value == 0):

if( pin_value == 0 ) {
MM_VPOT_SendJogWheelEvent(-1);
}
[/code]









this explains why it would be decremented twice before.



It doesn't explain why it has been decremented 3 ticks... but maybe this was just a wrong observation?
