Hello
I have a car Grande Punto. I would like to exchange information via OBDII socket.
I know very well microprocessor programming and serial communication.
uses a communication protocol, but in my vehicle, I do not know how.
for example, to let me know what code to the engine speed, which is the protocol (serial data xxxBPS, OneWire, SPI) need to send.
or to make anything (lights burn, be blocked doors) I do not know how I need to send a code.
I'll be happy to share the information with friends.
I wish everyone a good day.
