hi all iam using LPC1788 M3 cortex ARM 7 controller iam trying to execute the timer and serial interrupt program. in both the cases iam unable to return from the interrupt handler routine.
iam also working on LPC2378 ARM 7 controller where i have executed both the programs mentioned above. there iam using VICVECTADDR=0 to return from interrupt to main. what is the case in LPC1788? please help. Thanks in advance
Which port pin are you using as interrupt? Are you configuring the interrupt enable registers? (ENR/ENF) Have you enable the interrupt in NVIC? NVIC_EnableIRQ(GPIO_IRQn);
In case if you have the firmware library, there is an example code. refer to it.
