Exception in SoftPwmExample

[Olivier Le Diouris]

Using 1.2-SNAPSHOT, I am trying to run the sample at https://github.com/Pi4J/pi4j/blob/master/pi4j-example/src/main/java/SoftPwmExample.java.

If I understand correctly, the RaspiPin.GPIO_01 is the physical pin #12.

When I run the code, I have the following Exception:

Exception in thread "main" com.pi4j.io.gpio.exception.UnsupportedPinModeException: This GPIO pin [GPIO 1] does not support the pin mode specified [soft_pwm_output]
	at com.pi4j.io.gpio.GpioProviderBase.export(GpioProviderBase.java:115)
	at com.pi4j.io.gpio.WiringPiGpioProviderBase.export(WiringPiGpioProviderBase.java:90)

	at com.pi4j.io.gpio.impl.GpioControllerImpl.provisionSoftPwmOutputPin(GpioControllerImpl.java:876)

It runs OK from the shell:

#!/usr/bin/env bash
#
# pin GPIO_18 is #12
#
gpio -g mode 18 pwm
gpio pwm-ms
gpio pwmc 192
gpio pwmr 2000
gpio -g pwm 18 150
sleep 1
gpio -g pwm 18 200
echo Done.

Same in C, with wiringPi:

#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
#include <wiringPi.h>

int main (void) {
   fprintf(stdout, "Raspberry Pi PWM wiringPi test program\n");
   wiringPiSetupGpio();
   pinMode (18, PWM_OUTPUT); // Pin #12
   pwmSetMode (PWM_MODE_MS);
   pwmSetRange (2000);
   pwmSetClock (192);
   pwmWrite(18, 150);
   delay(1000);
   pwmWrite(18, 200);
   delay(1000);
   pwmWrite(18, 2000);
   delay(1000);
   pwmWrite(18, 200);
   fprintf(stdout, "Done\n");
   return 0;
}

Is there anything I missed to "enable" the pin GPIO_01 so it supports a soft_pwm_output ?

Any hint welcome, thank you!
