Hi all,
I am testing External Interrupt function with TRK-KEA128 now, but there never trigger the isr so need help.
1) Using CW10.6, ProcessorExpert to generate ExInt
2) Could only choose PTI4 for input (why? datasheet says PTI0~PTI6 could be set)
3) Input waveform with 10KHz, 1us width, 5V amplitude.
Any help is appreciated.
Solved! Go to Solution.
Hello KuanYuen,
How are you configuring the IRQ module because I can use PTI0 ~ PTI6 as IRQ pin and it works well? Here is the Init_IRQ component configuration:
I created a simple project where i trigger the IRQ everytime a '0' logic is presented in PTI0. On the ISR, i toggle the blue LED. Attach is the project that I used for testing it.
I hope this helps.
Best Regards,
Isaac

Thanks isaacavila, your setup is worked.
Somehow I don't understand why the ExInt module that I used doesn't work.
