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
#ifdef CHECK_ALL_80_PINS_CONFIGURATION_STATUS
}
}
for(;;) { };
}
