C127 Gear Indicator Boost Setting Display

Postby HKS_TRD on Sat Sep 25, 2021 7:20 pm

I'm using a counter in my PDM30 to select boost levels, 0 being boost control off and then counting 1,2 and 3.
I have managed to send the value to the C127 and have 1,2 and 3 displaying in the gear indicator as expected but when the counter is at 0 the gear indicator shows 'N' which I did anticipate but I wasn't sure how to have that display as 0 or any other value or possibly even have the indicator off if the counter is '0'

I am interested in this too. I have tried to use a C125 gear display as a current lap counter starting at 0 when on the start line and incrementing as soon as the heat starts, but also got the N instead of 0. I tried a conversion table, and anything else I could find searching the forum, but couldn't get a 0 to display.
The other posts I could find seemed to be from a while ago and involved getting zero to display as N, so I guess maybe something has been hard coded into recent firmwares so that 0's display as N in the Gear display.

With Fixed Display setups (ie not Display Creator ones) the centre number is hard coded as a gear indicator. Below is what is displayed for each channel value.

If you use -6 the display will show blank. I set up a counter from my driver switch to count from 0 to 4 postions. I then made a 2D table with the input being the counter output channel being 0=-6, 1=1,2=2,3=3 and 4=4. I then named the output channel of the 2D table "SKIDOO BOOST FOR GEAR DISPLAY" then simply used that channel in the gear and you will have you boost levels displayed or as I like to refer to it as "stage 1,2,3 ect" with a blank setting being zero.

You can also set it up so the display will only go down to or start at 1 by setting up your counter to start a 1 instead of zero then making the change in the 2d table.

Thanks, I didn't think to try an out of range number to see what was displayed.
