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
