first of all , i want to say hello i'm new here and this is my first post.
i'm a newb to mcu's so plz be patient guys.
the problem:
i've bought a gauge cluster unit for my motorcycle from a different model .
most of the time those gauges work alike , the speed sensor sends square wave signal which is translated by the gauges mcu to the 7 seg speed display.
the rpm sensor works the same way ... and the temp sensor also...
now with this new gauge i got , things are a bit complicated. it gets all the data via serial communication of some kind from the main engine control unit.
now i need to convert my sensors data to serial data , so it can be received by the gauge.
the problem is , i dont know what type of data is send , how many bits at a time... things like that.
the mcu inside is nec 78063 (a) , heres the datasheet i found

its a 8bit mcu .
any help would be great .
