i hope i post in the right place but if not, please inform me to post it in a more suitable place…
Let me describe my problem…
For my project, i use starterware (version 2.00.01.01) and build my files via code composer studio (version 6.1.0.00104) with compiler version:GNU v4.8.4 (Linaro).
My goal is to learn using interrupts. Thus i started with a simple project in mind: by pressing a switch i expect to create an interrupt in an input pin of my beaglebone and via the isr i created, i want to turn off a led that was already on and turn on an other, previously off, led.
The problem seems to be that i can not get an interrupt…
I give you the piece of code responsible for achieving my goal:
GPIODirModeSet(SOC_GPIO_1_REGS, GPIO_INTER_INP, GPIO_DIR_INPUT);
IntPrioritySet(SYS_INT_GPIOINT1A, 0, AINTC_HOSTINT_ROUTE_IRQ);
HWREG(SOC_GPIO_1_REGS + 0x34) = 0x10;
HWREG(SOC_GPIO_1_REGS + 0x38) = 0x10;
HWREG(SOC_GPIO_1_REGS + 0x44) = 0x10;
//``` //------isr function```
/* Clear interrupt */
HWREG(SOC_GPIO_1_REGS + 0x2C) = 0x10;` HWREG(SOC_GPIO_1_REGS + 0x30) = 0x10;
```//turn off led that is already on``` ```GPIOPinWrite(SOC_GPIO_1_REGS, GPIO_LED_ON, GPIO_PIN_LOW);
//turn on an other led
GPIOPinWrite(SOC_GPIO_1_REGS, GPIO_LED_2, GPIO_PIN_HIGH);` //again enable IRQ
//GPIO_IRQSTATUS_SET_0``` ```HWREG(SOC_GPIO_1_REGS + 0x38) = 0x10;//GPIO_IRQSTATUS_SET_1
Unfortunately, nothing happens when i push the switch…can somebody point out to me a possible solution or what is wrong with the above?
Moreover, how can i test if an interrupt is actually triggered or not when i push the switch?
Thanks in advance for any help
