You can't chart PIDs that are bit-mapped PIDs. You can add a "status" item to the dashbord and use it to display the bit-mapped PID.
Or you can create a calculated PID to extract just the info you want from that PID and cause it to return a numerical value that can be charted.
For example:
Code:
# ==============================================================================
# Units
# -------------------
# See sae_generic.txt for more information on the *UNITS section
*UNITS
#Code System Abbr Description
#-------- ---------- -------- -------------------------------------------------------------
None None "" "No units"
# ==============================================================================
# Add slot definitions here
# --------------------------------
# See sae_generic.txt for more information on "SLOT" formats
#
#Units Low High Fmt Expression
#------------ ------------- ------------- ---- --------------------------------------------------------------
*CLC-00-0001
None 0 1 0 "iff({GM.BRKR}&8)=8,1,0)"
# ==============================================================================
*PRN - Parameter Reference Numbers
# --------------------------------
# See sae_generic.txt for more information on the *PRN section
#
#Code PRN SLOT Units System Description
#------------------------- ---- ------------ ---------------- ---------------- ------------------------------------------
CALC.BRKPEDAL F400 CLC-00-0001 None Brakes Brake pedal active
The expression iff({GM.BRKR}&8)=8,1,0) returns 1 if the 3rd bit is set, otherwise it returns 0. You can tell which bit you want by right clicking on the PID and selecting "More info...". The bits are numbered from top to bottom where the top item is bit 7 and the bottom item is bit 0.
