Hey guys, is there a way to read in single-precision float values from a CANbus message? I have no issues reading unsigned and signed integers but can’t figure out how to read float values. Obviously DBC files don’t natively support floats but Holley ECU’s use floats exclusively so being able to re…

Every CANbus Input is represented in the PMU and ADU as a Singed 16-bit integer with 0, 1, 2, or 3 decimal places. We will add the decoder for float32 that will set 1000 if you receive the 1.0 value (for decimalPlaces=3). It will be relatively easy, as we have IEEE-754 float32 support in our CPU. S…
