No, I mean GPIO_NUM_15, because my interrupt is configured to GPIO_NUM_4. I am using GPIO_NUM_15 just to generate a test signal, so I can measure with my digital oscilloscope "easily" the latency of the interrupt raise time.
GPIO configuration:
External Interrupt on Pin: GPIO_NUM_4
Test Signal Output on Pin: GPIO_NUM_15
Program flow
- External Signal on GPIO_NUM_4 triggers the interrupt
- Program jumps to interrupt handler (xt_highint5)
- In xt_highint5: Program make GPIO_NUM_15 to HIGH
- In xt_highint5: Program clears the interrupt status of GPIO_NUM_4 (!!)
- Programm returns from interrupt but crashes with "Core 0 panic'ed (Unhandled Debug Exception")
