Programming Spartan 3 V2 Lite for analog gauge

Spartan 3 Lite
1

Hi all, I have a nice looking analog gauge in a car where previously an old innovate lc-1 was installed.

Is there a possibility to program my Spartan for it?

i think it needs this output; “linear output between 0V and 5V for an AFR of 7.35 to 22.39.”

I have the digital gauge from 14.7 as backup, but does not fit the rest of the car

Send the serial command: “SETLAMFIVEV1.52” and “SETLAMZEROV0.50” without the quotation marks.
