Why Arduino needs to be restarted after PS2 controller communication in Arduino? And how to to do this via coding? - interface

Question

When I ran the code for a drivetrain and opened serial monitor it was working, but when I powered on Arduino via dc Jack and ran the code. It was not working, because code is needed to restart after connection. I want to know that how can I solve this problem of PS2 communication and run my drivetrain without restart or starting serial monitor.
Code that I uploaded was given in this instructable

Answer 1

I got my answer by experimenting a lot. First thing is that you have to either restart your arduino or configure your pin after connection of ps2 to arduino. This can be done by 2 ways :
1) Restart arduino after connection by code or
2) configure again after connection
1 option you know well, i am discussing 2nd i.e configure :
as you know that you have already configured pins by function ps2x.config_gamepad();
Now you have to reconfigure it after connection of ps2 to arduino, you can use a function called reconfig_gamepad(); after read_gamepad(); in void loop.
my code for holonomic drive train is below find out comments // there are total four commented lines in code. good luck. Hope this will solve your problem also.

Answer 2

Here's how I did it.....
void setup()
{
Serial.begin(9600);
// retry logic to avoid a reset after power up
do
{
delay(1000);
error = ps2x.config_gamepad(13, 11, 10, 12, true, true);
if (error == 1)
Serial.println("No controller found, retry in a sec");
} while (error == 1);
if (error == 0)
{
Serial.println("Found Controller, configured successful");
Serial.println("Try out all the buttons, X will vibrate the controller, faster as you press harder;");
Serial.println("holding L1 or R1 will print out the analog stick values.");
Serial.println("Go to www.billporter.info for updates and to report bugs.");
}
else if (error == 2)
Serial.println("Controller found but not accepting commands. see readme.txt to enable debug. Visit www.billporter.info for troubleshooting tips");
else if (error == 3)
Serial.println("Controller refusing to enter Pressures mode, may not support it. ");
type = ps2x.readType();
switch (type)
{
case 0:
Serial.println("Unknown Controller type");
