Basically I am building this big data logger for my car. One of the devices I will be logging is my radar detector (and also displaying warning and so on).
I have a Valentine 1 Radar Detector. Lucky for me they released a entire technical book http://www.valentine1.com/v1info/ESP/
At first I was happy that someone had this working on an arduino https://github.com/tz1/bluev/tree/master/bluev_sketchhttp://harleyhacking.blogspot.com/2012/05/arduino-mega-adk-to-v1-howto.html
and it works just like it was made. Basically it was a AVRTool to Arduino IDE conversion.
The problem is that I don't know how to reverse engineer his C files and make them compatible with the Arduino IDE they way other libraries work.
So now I am trying to start this project from scratch. I took my logic analyzer and after reading the technical book I try to develop a clone signal to better understand the way it communicated.
I try to use Serial.write but I guess the communication pin just stays high before and after. There is also ONLY ONE DATA LINE so all the sending and receiving communication is done on the same wire.
So my question is,
What kind of communication is this?There is also ONLY ONE DATA LINE so all the sending and receiving communication is done on the same wire.
Is there a library for this communication Protocal?
Should I just use softserial?
I know that the other guy hook the TXPin and the MOSI pin (it a Mega) to the data line.
I am only trying to replicated the radar dector signal just to know how the display commands work exactly. I didn't understand page 23 on the manual.
