main.cpp contains the driver function, namely setup() and loop().
the include directory contains logic for each component. We separate them out for ease of debugging and reduce merge conflicts
Communication via the Arduino to host machine will be via USB Serial protocol at the baudrate of 9600.
The message from Arduino to host will be in the format of
<data1,data2,data3,...>. Namely with startMarker and endMarker wrapping each message, data encoded as string, and , as delimiter between data.
The message for mat from host -> Arduino will be in the format of
<ACTION, OPTIONAL, OPTIONAL>
where ACTION = s or a, standing for state or action respectively.
if ACTION = s, the arduino is not expecting OPTIONAL parameters, so the message is simply <s>, and the arduino will respond with the current state of the vehicle
if ACTION = a, the arduino is expecting throttle, steering, brake respectively. Sample message: <a, 1600, 1500, 1500>.
The Arduino is not going to respond to action if the manual control mode is ON for the vehicle. To turn manual control OFF, simply press and hold the button on the Radio controller.
This directory is intended for project header files.
A header file is a file containing C declarations and macro definitions
to be shared between several project source files. You request the use of a
header file in your project source file (C, C++, etc) located in src folder
by including it, with the C preprocessing directive `#include'.
#include "header.h"
int main (void)
{
...
}Including a header file produces the same results as copying the header file into each source file that needs it. Such copying would be time-consuming and error-prone. With a header file, the related declarations appear in only one place. If they need to be changed, they can be changed in one place, and programs that include the header file will automatically use the new version when next recompiled. The header file eliminates the labor of finding and changing all the copies as well as the risk that a failure to find one copy will result in inconsistencies within a program.
In C, the usual convention is to give header files names that end with `.h'. It is most portable to use only letters, digits, dashes, and underscores in header file names, and at most one dot.
