PS2X Library with arudino 3.3v 8Mhz?

Projects Programming

Hi,

When using PS2X Library with 5V Arduino Nano, it works fine. I try to convert it into wireless standalone controller, so I would like to go for Arduino 3.3V Mini Pro with 8 Mhz. Since I/O is 3.3V I should be able to skip the pullup resistors which i needed with 5V I/O.

The LED on PSX Controller is on, but I always get following message:
"Unknown Controller type found No controller found, check wiring, see readme.txt to enable debug. visit www.billporter.info for troubleshooting tips"

I assume some timings needs to be reconfigured, but I don't know which one and in which direction.
Does anyone managed to get it run on 8Mhz and can provide values for CTRL_CLK, CTRL_CLK_HIGH, CTRL_BYTE_DELAY?

Any need for additional resistors?

Thanks, Butch

I made some progress.

Without using any resistors the gamepad is found with following settings:

#define CTRL_CLK 10
#define CTRL_BYTE_DELAY 6

sometimes the pad is not recognized at first trial, so I made a loop around the gamepad configuration and try it until it works:

        int error = -1;
	while (error != 0)
	{
		error = ps2x.config_gamepad(PS2_CLK, PS2_CMD, PS2_SEL, PS2_DAT, pressures, rumble);


		if (error == 0)
		{
			Serial.print("Found Controller, configured successful ");
			Serial.print("pressures = ");
			if (pressures)
				Serial.println("true ");
			else
				Serial.println("false");
			Serial.print("rumble = ");
			if (rumble)
				Serial.println("true)");
			else {
				Serial.println("false");
				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(
						"Note: Go to www.billporter.info for updates and to report bugs.");
			}
		}
		else if (error == 1)
		{
			Serial.println(
					"No controller found, check wiring, see readme.txt to enable debug. visit www.billporter.info for troubleshooting tips");
		}
		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. ");
		}

		delay(300);
      }
