Hi C'688...
I can't as the real values will eventually be determined by trial and error on the initial build and calibration phases. the V to F relationship is none linear and will range from about 700Hz to 2800Hz; (anywhere in that region depending on the voltage).
As I have pointed out the longhand method works but it is not a lookup table and looks mighty ugly...
Each of the 16 possible values will have its own frequency range as its lookup.

Just a remark now the board has grown to considerable proportion.

Boy oh boy, with only a MONO mic input to use AudioScope gets much more difficult when the ALTDC board is included.
It needs, so far, two hits at the MIC input with a single hit at the HEADPHONE audio output.
The first at the highest practical resolution for the AC component and the second... (0 Replies)

pmpost
PMPOST(1) General Commands Manual PMPOST(1)
NAME
pmpost - append messages to the Performance Co-Pilot notice board
SYNOPSIS
$PCP_BINADM_DIR/pmpost message
DESCRIPTION
pmpost will append the text message to the end of the Performance Co-Pilot (PCP) notice board file ($PCP_LOG_DIR/NOTICES) in an atomic man-
ner that guards against corruption of the notice board file by concurrent invocations of pmpost.
The PCP notice board is intended to be a persistent store and clearing house for important messages relating to the operation of the PCP
and the notification of performance alerts from pmie(1) when other notification options are either unavailable or unsuitable.
Before being written, messages are prefixed by the current time, and when the current day is different to the last time the notice board
file was written, pmpost will prepend the message with the full date.
If the notice board file does not exist, pmpost will create it. pmpost would usually run from long-running PCP daemons executing under the
(typically unprivileged) $PCP_USER and $PCP_GROUP accounts. The file should be owned by root, and group writable by the $PCP_GROUP group.
FILES
$PCP_LOG_DIR/NOTICES
the PCP notice board file
PCP ENVIRONMENT
The file /etc/pcp.conf contains the local values for PCP_ variables.
