Example: GPIO
This test code shows how to configure gpio and how to use gpio interrupt.
GPIO functions:
- GPIO18: output
- GPIO19: output
- GPIO4: input, pulled up, interrupt from rising edge and falling edge
- GPIO5: input, pulled up, interrupt from rising edge.
Test:
- Connect GPIO18 with GPIO4
- Connect GPIO19 with GPIO5
- Generate pulses on GPIO18/19, that triggers interrupt on GPIO4/5
