Joule.md: Added Interrupt Pin assignment information

[swfFrg]

Verified that they worked with UBUNTU 16.04 LTS, Joule 570X, Tuchuck, BIOS #174, MRAA V1.5.1-24-g2ea6810

Setup: use "#define CHECK_ALL_80_PINS_CONFIGURATION_STATUS 1" if you want to check which pins are interrupt "configurable" If not defined, one "specified pin" can be tested with the interrupt handler 3 pin switch connected: to 1.8v J13.12 and GND J12.39, switch center pin connected to "Pin55" J13.15 in example below

Qt pseudo code: init mraa() call initIsrPins()

void myISR { static uint32_t myCnt = 0; qDebug("Interrupt GPIO!!!! %d\n", myCnt++); }

void initIsrPins(void) { mraa_result_t myStatus; uint8_t myPinNum = 1;

#ifdef CHECK_ALL_80_PINS_CONFIGURATION_STATUS for(myPinNum = 1; myPinNum <=80; myPinNum++) { mraa_gpio_context myIsr = mraa_gpio_init(myPinNum); #else mraa_gpio_context myIsr = mraa_gpio_init(55); // Manually enter Pin to test #endif

   if(myIsr == 0)
       qDebug("FAILED mraa_gpio_context");
   else
   {
       myStatus = mraa_gpio_dir(myIsr, MRAA_GPIO_IN);
       if(myStatus != MRAA_SUCCESS)
           qDebug("FAILED mraa_gpio_dir");
       else
       {
           myStatus = mraa_gpio_isr(myIsr, MRAA_GPIO_EDGE_BOTH, (void (*)(void*)) myISR, NULL);
           if(myStatus != MRAA_SUCCESS)
               qDebug("FAILED mraa_gpio_isr");
           else
               qDebug("Passed:%d", myPinNum);
       }
   }

#ifdef CHECK_ALL_80_PINS_CONFIGURATION_STATUS } }

for(;;) { }; }

Unfortunately changing the github issue title in the GUI is not enough, you need to actually amend to change the title, sign it off and push --force it.

If you get a change to fix this it would be great to merge it! Thanks

Sorry, I have been extremely busy. Shall attempt to do this next week.
