-####GPIO functions:
+## 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:
+
+## Test:
  * Connect GPIO18 with GPIO4
  * Connect GPIO19 with GPIO5
  * Generate pulses on GPIO18/19, that triggers interrupt on GPIO4/5
