Clearone Level 2 TP Bargraph

avi_dave

Since the clearone calculates all its ramping and gaining on a "DB" figure how should I throw this value to a TP bargraph I know there is some setting and or formula involved


level_event [dvClear1,1]
{
ClearVolResp = Level.sourcedev
send_level dvTP, 1, level.value
}


I get a error on compile, convert type dev to integer

The compile error is probably because of

ClearVolResp = Level.sourcedev

The RHS is a device, presumably the LHS is not.

Here is my code to adjust from the ClearOne AP800's range of -20..+20 to a range of 0..255

sinteger siVolumeMinimum = -20 (* or -66 depending on model *)
sinteger siVolumeMaximum = 20

sMyValue = itoa(type_cast(SignedAdjustFrom255(nArgVolume,siVolumeMinimum,siVolumeMaximum)))

(******************************************************************************)
define_function sinteger SignedAdjustFrom255( (* Result in range below        *)
   integer  nArgValue                  , (* Input  - Value in range 0 - 255   *)
   sinteger siArgMinimum               , (* Input  - Minimum input value      *)
   sinteger siArgMaximum               ) (* Input  - Maximum input value      *)
(******************************************************************************)                 
{
stack_var sinteger siMyValue

(* Have to do this to avoid a compiler warning *)
siMyValue                                        = type_cast(nArgValue)

return ((siMyValue * (siArgMaximum - siArgMinimum)) / 255) + siArgMinimum;
} (* SignedAdjustFrom255 *)   

However that's the wrong direction. I haven't yet had to code SignedAdjustTo255 but here is the unsigned version:

(******************************************************************************)
define_function integer AdjustTo255    ( (* Output - Result in range 0 - 255  *)                                                             
   integer nArgValue                   , (* Input  - Value to convert         *)
   integer nArgMinimum                 , (* Input  - Minimum input value      *)
   integer nArgMaximum                 ) (* Input  - Maximum input value      *)
(******************************************************************************)                 
{
return (((nArgValue - nArgMinimum) * 255) / (nArgMaximum - nArgMinimum));
} (* AdjustTo255 *)
