Hey,
this error comes from the initialisation of the gpio pins [0].
You can find that the default params of the srf04 [1] pins are set to
GPIO_PIN(0,13) and GPIO_PIN(0,14). Those are kind of logical pins - NOT
pins 13 and 14 on your hardware - and it seems RIOT does not provide
these logical pins on the arduino-atmega boards as given in the boards
config [2] (these are definitions for a family of arduino boards, one of
them is the uno).
You will have to set up your own params, to change the GPIO Pins to some
available pins from [2].

Hello,
I am currently trying the srf04 test and i constantly have the same
error "Error initializing".I did some digging but i can't find any
solution to this problem.I am using an arduino-uno for this task.
Thank you in advance!
